Last Tuesday morning, I began to feel the burning and tingling on my upper lip that signaled I was going to get a cold sore. I immediately started reading and searching through my herbal resources, eager to find a way to use herbs to help me heal more quickly. While I'm not sure what aspects of treatment were most effective, I was able to make what is typically a 10-14 day ordeal last only 7 days with the following:
1) Perhaps the best known natural treatment for cold sores is L-Lysine. L-Lysine is an amino acid found in fish, turkey, chicken, and legumes that interferes with the virus' ability to multiply. In addition to dietary sources, you can buy L-Lysine as a supplement from your local drug store. The dose I use during an outbreak is 1000 mg (1 gm) 3 times a day, as this seems to be the most common recommendation. People with frequent outbreaks can take 1000 mg a day to reduce or prevent future outbreaks.
2) Vitamin C. To help support my immune system, I took 1000 mg of vitamin C twice a day for 3-5 days. Similar options would include Airborne or Emergen-C twice a day.
3) Dietary Changes. Avoid foods high in the amino acid Arginine, which is found in chocolate, peanuts, and most nuts. (Yes, I successfully avoided chocolate during an outbreak. It can be done.) Arginine stimulates virus to multiply and basically counteracts the L-Lysine. Also avoid citrus fruit and juices while the virus is active.
4) Aloe. I have an aloe plant on my coffee table that provides me with healing juice for a multitude of injuries and ailments. In this case, once blisters formed, I cut a leaf and applied aloe juice directly to the blisters as often as necessary. This reduced the pain and swelling and also helped dry up the blisters.
5) Tea. I drank a soothing herbal tea containing camomile, lavender, and other soothing herbs. An outbreak is usually a reaction to stress, so relax, de-stress, and let your body heal. Traditional Medicinals makes a tea called "Easy Now" that I enjoy.
6) Lavender. Once my cold sore got to the scabbed and healing stage, I applied lavender essential oil directly to the sore 2-3 times a day. This helps it heal faster and prevent infection. Other essential oils such as Tea Tree may be equally effective; however, Lavender is the only oil that can be applied directly to the skin as is. Other essential oils should be diluted in a carrier oil as they may cause skin irritation and/or other adverse effects.
