For thousands of years Aryuvedic medicine has promoted Neem as the herb of choice to treat skin diseases. Neem moisturizes and protects the skin while helping to heal lesions, scaling, and rashes. Neem reduces inflammation, discomfort and itching, and can help prevent infections. Add several tablespoons of Neem oil or Neem leaf powder to a warm bath and soak for 20 minutes. Bathe or shower with Neem soap, apply a Neem lotion, cream, or salve several times a day to effected areas.
