Choosing Organic Skin Care Products

Today’s busy lifestyle means that our skin takes a battering from the elements and from all the chemical contaminants that we unavoidably come across at home and in the workplace. Recent research showed just how many unwanted chemicals we now have in our bodies. Some of these undoubtedly have been absorbed through the skin and most of these chemicals did not even exist 50 years ago. Unfortunately our quest for ever more cost effective cleaning, beauty and garden products has meant the introduction of new chemical concoctions, some of which are now being identified as potentially carcinogenic and dangerous and others as toxic. Our grandparents lived lives where natural skincare was the norm and undoubtedly skincare is more complicated today. But if we take time out to study the ingredients in our skincare products and chose them carefully we can chose the best natural skin care products.

Skin care is important, not only to keep you young looking, but also to assist in warding such dangers as skin cancer. With a major abundance of skin products on the market today, it is difficult to know which are most beneficial to your skin. All of them say they are good for your skin, but naturally that is part of the marketing strategy. One way to narrow down you choices for skin products is to choose organic natural skin care products.

The term “organic” refers to items that are not modified genetically, are not grown with the use of pesticides and involve no use of growth hormones. Many may wonder how organic can be used in terms of skin care. Simply put, the ingredients contained within the specific skin product are organic. This basically indicates that there are less chemicals and preservatives and more ingredients from nature. Something being natural refers to it as not being artificial. Therefore, when you combine the terms organic and natural you see that they both basically entail not using anything artificial. They are basically of the same meaning when placed in the context of organic skin care.

When you look at what makes a skin product organic and/or natural, you can see that often you can make your own home remedies for skin care. For example, a facial steam consisting of herbal tea such as green tea or chamomile opens pores and cleanses them of impurities. A mix of the same type of herbal tea combined with olive oil slathered on the face and body soothes and not only moisturizes, nourishes, but also cleanses and restores the skin. This is just a very small example of organic items that can be utilized to create your own skin care regime at home.

Another organic item of nature that you can use to treat your skin is raw honey. Raw honey has a natural antibiotic contained within that is useful for ridding the skin of some types of acne. Even if you don’t want to do a lot of research to find out how to create your own homemade skincare items, there are ways to ensure when buying products already made and marketed at stores are truly organic and truly appropriate.

First of all an item cannot be labeled as organic unless 95% of the ingredients contained in the product are organically grown. You must be careful when reading labels; however, because there are those that state that the product is made with organic ingredients. With this only 70% of the ingredients contained within the product are organically grown.

Skin care is important, not only to keep you young looking, but consider also that your skin is the largest organ of your body. Most people do not think of their skin that manner, but considering that it helps protect, detoxify, enables entrance of important nutrients into the body to keep you healthy and protects the body from environmental changes it is a vital part of one’s body that should be well taken care of.

Ayurveda Skincare for Acne and Aging

Being the mirror, the barometer of an individual’s health, skin is the clue to one’s Ayurvedic constitution. This can be understood by the types of skin that one has. Example: If vata is predominant the skin of a person is dry, rough, cold, thin with fine pores and wrinkled. In case of pitta constitution, the skin is delicate, fair and red toned with freckles, moles or acne and burns easily. If the constitution is of kapha dosha the skin of a person is oily, smooth, moist and thick with a tendency towards large pores.

If the skin is not cared properly and neglected it suffers from premature aging, becomes dull and blemished. Regular consumption of milk, honey and yogurt are good nourishment for skin and prevents premature aging.

Following are some common skin problems and ayurvedic remedy for preventing and curing the same.

Acne and Pimples

The aggravation of tridosha or the three energies of the body results in the occurrence of acne, pimples and blackheads. In all pitta dosha is effected the most and it happens so due to the excessive intake of alcohol, tea, coffee, spicy, oily and fried foods. Stress, tension, pollution and chemicals are also among the major causes that aggravates Pitta dosha and result in acne, boils, pimples and rashes.

Remedies

* A paste made from one teaspoon each of sandalwood powder and turmeric mixed with milk, is very good. A paste of nutmeg and water is also beneficial.
* Half a cup of Aloe Vera pulp can be taken internally (Do not take internally if pregnant) or applied externally to the skin. Dosage: Twice a day.
* Before going to bed, was the face thoroughly and then apply a paste of 1 Tsp. coriander juice mixed with a pinch of turmeric powder.
* For pimples, apply a paste made from one teaspoon of cumin seeds. Remove after one hour.
* A paste of fresh fenugreek leaves, applied and washed off with warm water before going to bed prevents pimples.

Pigmentation

Imbalance of Bhrajaka Pitta that colors the skin and can be compared to melanin causes blackening, pigmentation and discoloration of skin. Excessive exposure to the sun, irregular eating, sleeping habits and consumption of foods and drinks that aggravate pitta are responsible for the aggravation of bhrajka pitta also.

Remedies

* Grind five almonds and mix with 1 teaspoon of fresh cream and a few drops of lemon juice. Apply this paste to the face and neck. Leave on for
about fifteen minutes.
* Apply papaya juice, or mashed papaya, to the affected areas.
* Grind equal amounts of sesame seeds and turmeric in a small quantity of
* Water Apply to the face or discolored skin.
* Make a paste from basil (tulsi) leaves and water to use on the affected skin.

Premature Aging

This is due to the aggravation of vata dosha, which naturally increases with age. Thus aging is something that can be prevented to come to early but can’t be cured as such. It’s a natural ongoing process and beyond human limit to control it.

Aging causes dryness and wrinkling of the skin. Factors like excessive thinking, stress, tension, over work, strain, irregular sleeping and eating habits and cold or dry foods enhance aging. Foods containing artificial flavors, colors, preservatives and chemicals also aggravate the Vata dosha and fasten aging.

Remedies
* Massage the face with ghee, almond oil or coconut oil before going to bed.
* Use grated cucumber in a face pack.
* Apply fresh aloe Vera gel to the skin.

Complementary and Alternative Health Practices

By: Van Le |

Complementary and Alternative Practices towards a Healthy Lifestyle. Over the last century, doctors and researchers in the Western world have made several medical breakthroughs and significant discoveries in the fight against terminal diseases.  Such discoveries are key milestones towards finding the cure for diseases such as cancer and other illnesses, however, the idea of using complementary and alternative medicines, remedies, and holistic therapy to help manage a natural, healthier lifestyle is gaining popularity in the Western world.

Complementary and alternative medicine consists of practices that do not follow the norm of conventional medicine; complementary medicine is used in conjunction with conventional medicine, while alternative medicine is used in place of conventional treatment.  Some examples of complementary and alternative medicine include acupuncture, meditation/visualization, and the use of natural products.

Acupuncture
Acupuncture, a complementary medicine technique, is the practice of inserting tiny needles into very specific parts of the body to relieve pain and discomforts associated with conventional treatments.  According to the National Center for Complementary and Alternative Medicine (NCCAM), it is the oldest healing practice in the world, and works by restoring the body’s balance (ying and yang.)  Acupuncture is most popular for its ability to relieve pain and aches, but the idea of “cosmetic acupuncture” is also gaining attention as a less-drastic alternative to cosmetic surgeries.

It has been reported that those who undergo cosmetic acupuncture experience vibrant skin tone, reduced and finer wrinkles, and firmer skin.  A study in The Journal of Clinical Acupuncture states that 90% of cosmetic acupuncture patients experience notable improvement in their skin quality.  As with any medical procedure, acupuncture carries risks, and when considering an acupuncture treatment, it is important to examine the creditability and equipment of the practitioner.

Meditation/Visualization
Meditation is a complementary technique used to escape from the stress of our hectic lifestyles and reach a profound state of relaxation and calmness.

There are several types of meditation, including yoga and tai-chi.  Yoga consists of molding the body into postures, using controlled breathing, and focusing on the moment to escape from the day’s stress.  Tai-chi started as a form of martial arts but has transformed into a healing practice.  Those who practice tai-chi move their bodies slowly and mindfully while focusing on their breathing.  According to the Associated Press, tai-chi helps build a stronger immune system, which can help the body fight against shingles, a skin condition that cause rashes.  Visualization, also known as mental imagery, is a technique in which the mind focuses on a specific image.  Cancer patients sometimes use this technique to envision their bodies fighting off the disease.  Visualization can be used by anyone to relieve stress from a busy day.

Use of natural products
The popularity of natural products has increased exponentially in the last few years due to its ability to generate healthy skin from the inside out.  Products that contain natural ingredients as opposed to harsh chemicals are logically better for the body and skin.  From a diet filled with healthy choices to using natural skincare products, there are several ways to generate a healthy, more fulfilling lifestyle.  By choosing blueberries over Botox, you can achieve longer-lasting and healthier results.  Switch to an all-natural line of skin care products to give your skin a break from the preservatives and lab-generated chemicals that can wreak havoc years down the road.

Facial Care for Men

By Ravi Thiagarajan

When it comes to skincare, there is always a tendency among men to think, “Who cares, I’m a guy.” Lack of motivation to take care of their faces will give most men dull skin.. Sometimes a guy might think “Well, I lift weights, that’s enough,” or “Facial care is for girls.” That could not be any further from the truth. Good facial care helps in retaining proper skin texture in the long run.

Gentlemen, if you care what the ladies think, your facial care is extremely important. It is never good for a guy’s self confidence if your date cringes when you lean in to kiss her. That is why it is totally necessary to incorporate some kind of male facial care routine to help keep your skin looking clear and healthy. Here we focus on some basic yet important things that can make a big difference.

Shaving
For guys who aspire to keep a cleanly shaved face, we are forced to deal with the monotonous task of shaving each and every morning. Too many guys rush through it or give a poor effort, which results in redness, bumps and irritation. Shaving is something that should be done carefully in its entirety.

Experts claim having is best done after your shower because it makes your skin soft and removes the dirt and dead cells. Many guys should use a shaving cream and razor that will give them a very close shave but also protect their skin at the same time. With so many shaving creams on the market shelves, it is sometimes tough to decide which one is better than the other. By not continuing with one, we may spoil the benefits of using the same product.

Experimenting is good thing but long term effects are negative as your skin tries to adjust to ever-changing ingredients. I find many new herbal creams that are made by smaller, organic companies to be better than then the usual chemical-laden choices when it comes to men’s skin care on the market. Their products contain the vitamin E and Aloe to help protect and smooth skin as well as hydrate and moisturize. Use of an effective razor is equally important. Again selecting a proper blade is essential. Gillette sells its Mach3 line of new blades in different sizes and numbers now, which makes me even more confused. They started with twin, then came the ‘3 slot super shave’ and now it’s the ‘4 cutter fine shine!’ Any of these variations of razors will do the job, really well or if you prefer electric that’s fine too. Just make sure the blades are clean and sharp – very few women are attracted to werewolves.

Acne
Acne is the mother of all skin problems and it is just a horror if you are trying to impress the ladies. If you are a college guy, you most likely have past your worst acne stage but you never know what Mother Nature has in store for you. Acne becomes the prime concern when men are in their 20s and 30s - just about the time you are dating or looking for that first big job - where appearances are the key. Busy lifestyles have added stress that according to some reports, has created acne issues rising from 20% to 60% last two years. So, “why me?” you might ask.

The short version of the complicated answer is this. Acne can be caused by a number of things – hormones, diet, poor hygiene, lack of cleansing – or none of these things. It all depends on your body chemistry. But once you have it, you just want it to go away. Before choosing an acne product, familiarize yourself with the ingredients. Some brands use harsh chemicals to kill acne bacteria. The down side to this is these chemicals can also negatively affect your skin in the long run.

There are hundreds of various adult skin care products for acne on the market today. Most of these products require at least a month of steady usage to get results. Be sure that you are giving whatever product you choose at least 4-6 weeks before you discontinue use. If you stop using a product sooner than this then you could risk wasting time and money on a product that otherwise would’ve cleared your skin.

Dry Skin
Among other skin problems, dry skin is definitely one to be aware of. Normally healthy skin is coated with a layer of lipids and some fatty substances, which keep the skin supple and soft. Dry skin has a low level of sebum and can be prone to sensitivity. The skin has a parched look caused by its inability to retain moisture. It usually feels “tight” and uncomfortable after washing unless some type of moisturizer or skin cream is applied. Chapping and cracking are signs of extremely dry, dehydrated skin. Dryness is exacerbated by wind, extremes of temperature and air-conditioning, all of which cause the skin to flake, chap and feel tight. This type of skin is tightly drawn over the bones. It looks dull, especially on the cheeks and around the eyes. There may be tiny expression lines in these spots and at the comers of the mouth.

Apply Moisturizer Frequently
Both genders are capable of getting dry skin and the best way to prevent dry skin from rearing its ugly head is to consistently use a facial moisturizing lotion on an everyday basis. There are many tips and advice on how to take care of your face. However, the most common and consistent advice is to avoid the sun and moisturize your face.

Ok, my skincare lesson is over.   Here’s a little joke on a lighter note:

Every man believes every woman’s ultimate fantasy is to have two men at once.-
While a recent sociological study verified this, what men don’t realize is that, in women’s fantasies, one man cooks while the other cleans!

Using Yantra in Ayurvedic Herbalism

Yantra simply means ‘device’ in Sanskrit, and similar to devices like radios that tune into certain frequencies, yantras both tune into and amplify very specific vibrations that are salubrious to our herbal intentions. How does this spell healing to the Ayurvedic practitioner and their client? There are many reasons but here are some to ponder.

Yantra - Good for the Herbs
The Yantra is considered to be a geometrical equivalent of a mantra, and so it is about generating or modulating vibrational energy. Since the Yantra is more static, the vibration is steady, like a standing wave ‘trapped’ or ‘channeled’ by boundaries and filters. It also tends to be precise more often than a mantra. This particular vibration enhances the power of the herbs; it is like having a Gyoto monk or a Kashi pujari personally attending the herbs and continuously chanting empowering mantras. In fact, when using mantras to empower herbs, I have found that first directing the mantra through a yantra seems to focus the power of my sankalpa (intention). As Vamadeva points out, it creates a pattern in the herbs that will more effectively hold mantras.

Because a properly made Yantra invokes a pure, non-vitiated vibration, it activates the pure activities of an herb. For instance, Ashwagandha will create more Ojas than Kapha when used with a Yantra because Ojas can be seen to be the pure form of Kapha. The same goes for Prana and Tejas. The right yantra can also make herbs more Sattvic, while another yantra, say of a Goddess like Kranti, can make the herbs Rajasic. The choices of the herbalist are not “good or bad”, but rather about which energies are preferable: sometimes it is Rajas or Tamas.

Yantra - Enhances Practitioner Herb Wisdom
The Yantra is an archetypal symbol that can trigger the ability to innately know what an herb is good for and if it is good for you. It has this power because by looking at it, certain energetic structures in our subtle bodies are activated that allow a direct link to an intuitive knowledge of the herb. In other words, when you look at a jar of herbs on which a yantra is placed, your eyes read the text under the label or visually inspect the herbs, but your third eye reads the yantra, and gets to the codes to open up a part of you that can hear what the medicine is saying. Of course, only a great Vaidya Yogi can fully do this, but I am sure it happens subtley for some and subliminally for others. Tradition is that the same exact yantra actually exists inside of us, in the patterns of certain inter-chakra nadi networks within the within.

If we are lucky and skillful, a Yantra can be programmed, or requested, to gather and hold our accumulated collective efforts, thereby building the Prana of the remedy, the clinic, or the vaidya. Of course, any logo can do this, but to the extent that the yantra carries and promotes a special Shakti, it enhances above any other logos of our enterprises.

Utilizing Yantra
Respect is the key to correct use of a yantra as it is the mansion of a particular goddess embodying a cosmic principle. Since the moon significantly helps to govern the Soma in the herbs, I often will place a large Sri Yantra engraved on a Silver, Copper or Gold plate on top of the herbs and place this overnight out in the light of the full moon or during some other auspicious muhurta (moment). The Yantra can also be placed on the herb jar label. Yantras are more powerful when engraved in metal, so in India I once commissioned an artist to engrave the Sri Yantra in the metal tops of my herb jars. They were beautiful and I feel the Goddesses who empower herbs appreciate beauty and are more likely to take up residence in herbal practices and apothecaries that embrace and radiate beauty. Well made and skillfully used Yantras can promote this beauty.

It is best to practice Yantras within the whole of the tradition to fully utilize its synergy; it will not thrive when torn from its Vedic roots. Good results can be generated with the judicial use of these mystic diagrams, but like any Vedic science, the use of Yantras is best learned directly from the Yantra and from an experienced expert, and not from mere written words. In fact, to be assured that I have a great expert on my side who will rectify my mistakes and lack of skill, I almost always use Yantras that I have personally immersed into the Ganga to invoke her Divine blessings. As Ayur, the continuity aspect of consciousness, is a hologram, Yantra helps us reflect That.

Skincare Regimes to Prevent Acne

Acne affects all types of skin types, and at one time or another, chances are you too have experienced an outbreak. The best way to control acne and prevent further breakouts from occurring is to practice a regular skin regimen.

The basis of the skin care process for acne conditions is to adopt the habit of taking a gentle wash every morning and every evening and even after a round of heavy exercise. This will not only make you feel cool on the face but also unclog the pores on the skin surface. Also, it is necessary to make a close study of your hair. Specially, in the case when your hair have a tendency to become oily. You must adopt the habit of daily shampooing to prevent the oil from coming on the forehead and causing acne to attack the facial skin.

In the same way, when on a holiday or when working in the outdoors, you must avoid the risk of sunburn or the luxury of suntan. Only recently have medical analysts realized that not only do such practices cause acne conditions, they also processes the conditions that cause skin cancer. Thus a safe way out is to avoid the tanning sunburn routine altogether and take effective skin protective gear and lotions and applications to prevent the harsh effects of the sun from falling on the skin and causing acne.

When going out for a special date in the evenings or even when you are getting dressed for a day at work, you must scrupulously avoid make-up that is oil-based. Also, make-up on the face while at work is going to remain for quite a few hours. So, it is very necessary to take proper skin care daily and prevent acne occurrence. The best bet for acne skin care is to choose products that are noncomedogenic as such products do not promote the formation of closed pores and thus eliminate the danger of clogged pores, the most common problem leading to acne conditions.

For menfolks, who have to look presentable and smart at the workplace and who need to take a close shave prior to going under the shower, it is necessary to soften the beard before putting the razor to the face. This will help the skin remain smooth and not break into acne. Also, the acne-hit skin can be smoothly shaven over if the surface is soft and the razor can glide freely and gently over the surface.

Thus acne skin care is a matter of closely watching for signs of danger surfacing on the face and also preventing such signs from attacking the skin. This dual advantage can be gained by taking proper skin care precautions to avoid acne conditions.

What is the Best Skin Care?

Everyone wants their skin to look its best. Here are some simple tips you can follow to help avoid skin problems:

• Acne or Rosacea Skin:
  Plan ahead: if you have a skin condition like acne or rosacea, see a dermatologist at least 3-4 months ahead of the big day (and sooner, if possible), so that your condition can be brought under control and so that your skin can heal up in time for the occasion. Check out www.AcneGuide.ca or www.RosaceaGuide.ca for treatment information.
• Wrinkles, Unwanted Hair or Sweating:
  Are you thinking of having treatments like Botox® (for frown lines, or to control excessive sweating), fillers like Restylane™, Juvederm™ and Artecoll™ for wrinkles, creases and scars, or laser treatments for unwanted hair or to remove broken blood vessels from the face? You should aim to have these treatments completed about 3 weeks before the event, so that the benefits of treatment will have fully developed, and so that any side effects of treatment like redness or small bruises will have resolved. Discuss the plans and timing with your dermatologist so that these things can be taken into account when scheduling your treatments. (Read more about Botox®)
• New Cosmetics:
  If you want to experiment with cosmetics, you should do so well in advance, to reduce the risk that an allergic or irritant reaction will interfere with your enjoyment of the event.
• Sun Tanning:
  Sun protection is important in the weeks leading up to an important event, to reduce the risk that you will have sunburn or peeling on the big day. It is also important to avoid experimenting with tanning beds in the weeks leading up to a major event, in case you have an undesired reaction to the UV light.
• Self-Tanning:
  Self-tanning creams and spray-on tans should not be used for the first time within three weeks of a major event, in case there is an allergic reaction or an unusual or uneven color is created. If you want to use such products, start to experiment with them several months ahead so that you can learn how to obtain safe, reliable results. Remember that the pigment created by many self-tanning products can discolor fine clothing, so it might be best not to apply them within a week of a public event.

What if there is a dermatological emergency like a flare-up of acne or an allergic reaction on the face in the days before a wedding, graduation or other important day? Fortunately, many of these problems can be helped by modern medical treatments. Your doctor may be able to arrange a high priority appointment with a dermatologist if they explain that there is an important event coming up – most of us, and most of our staff have been through these things ourselves and we are very sympathetic.

Don’t Diet - Eat Well

Healthy Foods for a Healthy Lifestyle

There are several fad diets that will lead to successful weight loss if you follow them exactly as they are designed. That doesn’t mean every food that fits into a diet is a healthy food, but it does mean you have to change your eating patterns to fit the diet’s rules.

Rather than worry about following a fad diet, think about your health and your lifestyle instead. Start by learning which foods are good for you.

Healthy Foods to Eat

The closer a food is to its natural state, the better it is for you. Fresh fruits and berries are great and will satisfy a craving for sweets. Whole vegetables have lots of vitamins and minerals, so eat more green, orange and yellow vegetables. Steam them to retain the most nutritional value and be careful with sauces, they may be high in calories and fats that aren’t good for you.

Any pasta or baked goods should be made from whole grains. Avoid sugary snacks and pastries as well. An apple is good for you, an apple pie really isn’t.

Shop for lean meats and don’t forget the fish. The omega-3 polyunsaturated fatty acids in ocean fish are often deficient in our diets, so serve seafood two or three times per week. Baked fish and chicken are healthier than fried, and lean meats like bison or venison may be healthier than higher fat beef.

Processed lunch meats, hot dogs, bacon, and sausages have a lot of saturated fat and nitrates in them you don’t want in your body. If you love these meats, you can find healthier versions sold at health food stores.

Remember to eat a variety of foods to get all of the vitamins and minerals you need to be healthy.

Stick to water, milk and 100% fruit and vegetable juices as your main beverages and limit sugary soft drinks. If you get tired of plain water, add a slice of lemon or lime to add a touch of flavor. For kids, try some fruit juice jazzed up with carbonated water.

Unhealthy Foods

• Battered and deep fried foods
• Sugary sodas
• Processed lunch meats
• Greasy snack chips
• White bread and refined pasta
• Most canned spaghetti and ravioli
• Sugary breakfast cereals
• Frozen fried chicken, fish sticks and corn dogs

Healthy Foods

• Green and brightly colored vegetables
• Dark leafy greens and lettuce
• Fresh fruits and berries
• Lean turkey and chicken
• Nuts, dried fruits and healthy snacks
• Whole grain breads and pasta
• Healthy cooking oils like canola and olive oils
• Grass fed beef and bison
• Cold water oily ocean fish
• Low fat milk or soy beverages
• Nuts, seeds, and legumes

Assess Your Lifestyle

Once you learn which foods are good for you, you need to look at your eating habits. If the foods you eat are not healthy, you might want to work within your habits and current lifestyle conditions, since they are usually tough to change. Consider these questions, then read on for tips to help you add healthy foods:

• Do you eat because you are bored, sad, or happy?
• Do you snack in front of the TV without even giving it much thought?
• Are most of your meals eaten at home or in restaurants?
• How often do you eat fast food?
• Do you like to cook?
• How often do you grocery shop?
• Do you skip breakfast or lunch, then overeat later in the day?
• How big are the portions you consume?
• Do you crave sweets?
• Are there foods you won’t give up?

Healthy Foods for Snackers

If you are an emotional eater, keep the junk food like potato chips, tortilla chips, ice cream, and candy out of the house. Keep healthy snacks like fruits, crunchy vegetables with dips, or nuts handy. If you absolutely feel the need for a treat, then purchase a small piece of high quality chocolate or your favorite treat and enjoy it, just don’t buy any to bring home. The same tips are helpful for those who enjoy TV snacking at home. If you don’t want to give up nibbling while watching your shows, keep low calorie foods close by, because it is very easy to eat too much when you are entranced by your favorite drama, football game or cooking show. Eat crisp raw vegetables with your dip instead of greasy chips.

Understanding UVA and UVB

From the Skin Cancer Foundation: For a six billion-year-old star, the sun is certainly in the news a lot lately, mainly because it is still a source of uncertainty and confusion to many of us. The center of this confusion is the sun’s ultraviolet A (long-wave) and ultraviolet B (shortwave) rays. Our understanding of exactly what kinds of damage each causes to the skin, and how best to protect ourselves, seems to shift every year as new research comes out. For example, it was once thought that only UVB was of concern, but we keep learning more and more about the damage caused by UVA. And new, improved forms of protection against UVA keep emerging. Keeping up with these new developments is a worthwhile challenge that can help all of us prevent sun damage. What is Ultraviolet Radiation? UV radiation is part of the electromagnetic (light) spectrum that reaches the earth from the sun. It has wavelengths shorter than visible light, making it invisible to the naked eye. These wavelengths are classified as UVA, UVB, or UVC, with UVA the longest of the three at 320–400 nanometers (nm, or billionths of a meter). UVA is further divided into two wave ranges, UVA I, which measures 340-400 nanometers (nm, or billionths of a meter), and UVA II which extends from 320–400 nanometers. UVB ranges from 290 to 320 nm. With even shorter rays, most UVC is absorbed by the ozone layer and does not reach the earth. Both UVA and UVB, however, penetrate the atmosphere and play an important role in conditions such as premature skin aging, eye damage (including cataracts), and skin cancers. They also suppress the immune system, reducing your ability to fight off these and other maladies. UV Radiation and Skin Cancer By damaging the skin’s cellular DNA, excessive UV radiation produces genetic mutations that can lead to skin cancer. Both the U.S. Department of Health and Human Services and the World Health Organization have identified UV as a proven human carcinogen. UV radiation is considered the main cause of nonmelanoma skin cancers (NMSC), including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). These cancers strike more than a million and more than 250,000 Americans, respectively, each year. Many experts believe that, especially for fair-skinned people, UV radiation also frequently plays a key role in melanoma, the deadliest form of skin cancer, which kills more than 8,000 Americans each year. UVA Most of us are exposed to large amounts of UVA throughout our lifetime. UVA rays account for up to 95 percent of the UV radiation reaching the Earth’s surface. Although they are less intense than UVB, UVA rays are 30 to 50 times more prevalent. They are present with relatively equal intensity during all daylight hours throughout the year, and can penetrate clouds and glass. UVA, which penetrates the skin more deeply than UVB, has long been known to play a major part in skin aging and wrinkling (photoaging), but until recently scientists believed it did not cause significant damage in areas of the epidermis (outermost skin layer) where most skin cancers occur. Studies over the past two decades, however, show that UVA damages skin cells called keratinocytes in the basal layer of the epidermis, where most skin cancers occur. (Basal and squamous cells are types of keratinocytes.) UVA contributes to and may even initiate the development of skin cancers. UVA is the dominant tanning ray, and we now know that tanning, whether outdoors or in a salon, causes cumulative damage over time. A tan results from injury to the skin’s DNA; the skin darkens in an imperfect attempt to prevent further DNA damage. These imperfections, or mutations, can lead to skin cancer. Tanning booths primarily emit UVA. The high-pressure sunlamps used in tanning salons emit doses of UVA as much as 12 times that of the sun. Not surprisingly, people who use tanning salons are 2.5 times more likely to develop squamous cell carcinoma, and 1.5 times more likely to develop basal cell carcinoma. According to recent research, first exposure to tanning beds in youth increases melanoma risk by 75 percent. UVB UVB, the chief cause of skin reddening and sunburn, tends to damage the skin’s more superficial epidermal layers. It plays a key role in the development of skin cancer and a contributory role in tanning and photoaging. Its intensity varies by season, location, and time of day. The most significant amount of UVB hits the U.S. between 10 AM and 4 PM from April to October. However, UVB rays can burn and damage your skin year-round, especially at high altitudes and on reflective surfaces such as snow or ice, which bounce back up to 80 percent of the rays so that they hit the skin twice. UVB rays do not significantly penetrate glass.

Herbal Remedy Could Halt Peanut Allergy

FRIDAY, Feb. 13 (HealthDay News) — A new herbal formula based in ancient Chinese medicine may be able to control allergic reactions to peanuts and other foods, researchers from New York City’s Mount Sinai School of Medicine report.

Food allergies are potentially life-threatening for children and adults. Food allergies among children have increased 18 percent since 1997, and in 2007, some 3 million U.S. children had food allergies, according to the National Center for Health Statistics. Currently, there is no treatment for the allergies, so avoidance is the only protection.

“We can reverse the peanut allergic reaction,” said lead researcher Dr. Xiu-Min Li, director of the Center for Chinese Herbal Therapy for Allergy and Asthma at Mount Sinai.

In addition, protection from allergic reactions to peanuts persisted for almost nine months after treatment was stopped, Li said. “The herbal formula can stop peanut allergy and produce a prolonged protection,” she said. “This formula may be effective for human peanut allergy.”

The report was published in the February online edition of The Journal of Allergy and Clinical Immunology.

For the study, Li’s team tested their new herbal remedy, called Food Allergy Herbal Formula (FAHF-2), on mice allergic to peanuts. They found that the formula protected mice from allergic reactions from peanuts.

In fact, FAHF-2 protected the animals from anaphylaxis for more than 36 weeks after treatment was stopped. This is one-quarter of the mouse life span, Li noted.

Li’s team has also shown the formula protects mice against other food allergies including tree nut, fish and shellfish.

Based on these findings, FAHF-2 has been given investigational new drug approval by the U.S. Food and Drug Administration; a human trial started last year.

The trial is testing the safety and effectiveness of the remedy for a variety of food allergies including peanut, tree nut, fish and shellfish, Li said. “The results of the trial have shown that FAHF-2 is safe and well-tolerated,” she noted.

In addition to FAHF-2, Li’s team has developed an herbal formula to treat asthma. That formula is also being tested in human trials, she said.

Dr. David L. Katz, director of the Prevention Research Center at Yale University School of Medicine, said that no matter where it comes from, a cure for peanut allergy would be an important breakthrough.

“This paper suggests that traditional Chinese medicine may offer promising therapy for peanut allergy,” Katz said. “This is less surprising than it may seem.”

First, it is probable that the use of herbs as medical therapy over a span of many centuries would distinguish the helpful from the useless and harmful by a process of trial-and-error, Katz said. Second, most drugs are derived from plants. “So, the actual differences between pharmacotherapy and herbal therapy are differences of degree, not kind,” he said.

When traditional Chinese medicine works, doctors want to know the science of how it works, Katz said. “But for the sake of their patients, conventional practitioners should look past terminology that may make them wince to see the promise of new and potentially effective treatments.”

Allergic reactions to food can range from mild hives to vomiting to difficulty breathing to anaphylaxis, the most severe reaction. Anaphylaxis causes muscles to contract, blood vessels to dilate and fluid to leak from the bloodstream into the tissues. This can result in narrowing of the upper or lower airways, low blood pressure, shock or a combination of these symptoms, and also can lead to a loss of consciousness and even death.
