What can i do for a cold sore?

Several things: Lysine. Use tea tree oil on it with a qtip...Stings but helps it resolve faster. Use homeopathic rhus tox...Can sped healing by several days. Acupuncture and chinese medicine can help as well. Call or see your doctor and ask bout anti-herpes medication like valtrex (valacyclovir). Eat cooling foods like cucumbers and pears and avocado.

Agree w Dr. Franz: Your doctor can prescribe valtrex (valacyclovir). Melissa officinalis or lemon balm (cream) has been shown in european studies to help expedite healing of cold sores. It can reduce healing time by half. Studies also show that regular use can help v recurrences. Brief supplementation w lysine 1, 000mg orally 3x a day at the onset, can also hasten healing. Your dermatologist can also provide laser treatments.
