Clinical Bottom Line/Effectiveness

Brief Background:

  • Neem is thought to have originated in Assam in northeast India, and Myanmar, where it is common throughout the central dry zone.
  • Neem has been used to treat infections, skin conditions, and reduce swellings. It is also used as a pesticide to protect food and other products from being eaten by insects. The antimicrobial properties of neem leaves and seed oil have long been recognized for their benefits to the skin and hair.
  • The extracts from neem often have a pungent smell similar to garlic. This is because they contain sulfurous compounds. The sulfur smell of some extracts can be overpowering and has often limited the commercial development of products containing neem.
  • Neem has been reported to reduce plaque formation, act as a mosquito repellent, treat psoriasis vulgaris and aid in the healing of gastroduodenal ulcers. However, there is currently insufficient evidence to recommend for or against these uses.
