Neem

1. May Promote Hair Health

  Neem seed extract contains azadirachtin, an active compound that may fight parasites that affect hair and skin, such as lice. Azadirachtin works by disrupting parasite growth and interfering with reproduction and other cellular processes. In a study that tested the efficacy of a neem-based shampoo on head lice in children, leaving shampoo in the hair for 10 minutes killed the lice while being gentle on the skin. Neem extract and nimbidin, a compound found in neem oil, may also treat dandruff due to its anti-inflammatory and antimicrobial properties. Dandruff and scalp irritation may result from fungal buildup on the scalp.  

2. May Boost Dental and Oral Health

  Chewing neem bark to promote oral hygiene is a common practice in India. Neem’s antiseptic, anti-inflammatory, antioxidant, and immune-boosting properties may promote oral health. Although more research is needed, studies indicate that neem may relieve pain and help treat gingivitis, periodontitis, and tooth decay. Furthermore, test-tube studies suggest that neem may minimize bacteria’s ability to colonize the surface of your teeth, thus reducing plaque formation. Plus, in a 21-day study including 45 people with gingivitis, neem mouthwash was found to be as effective as chlorhexidine mouthwash — a heavy-duty prescription mouthwash — at reducing gum bleeding and plaque.  

3. May Aid Liver and Kidney Health

  Neem’s antioxidant and anti-inflammatory properties may help fight oxidative stress, which may in turn promote liver and kidney health. Oxidative stress is caused by a buildup of unstable molecules called free radicals. Although your body naturally produces free radicals as a byproduct of metabolism, external sources increase their presence. Some drugs, including cancer medication, painkillers, and antipsychotics, may contribute to oxidative stress, leading to tissue damage in your liver and kidneys. Interestingly, one study on rats found that neem leaf extract reduced liver damage induced by high-dose acetaminophen. Another rat study showed similar effects, suggesting that neem extract improved kidney tissue damage caused by chemotherapy medication. However, studies in humans are needed.  

4. May Improve Skin Health

  Neem seed oil is rich in fatty acids, including oleic, stearic, palmitic, and linoleic acids. Collectively, these fatty acids have been shown to have anti-inflammatory, antioxidant, and antimicrobial properties that promote healthy skin. Keep in mind that while Ayurvedic medicine — an Indian traditional healing system — uses neem to treat psoriasis and eczema.  

5. Acne

  Historically, neem has been used to treat acne, reduce blemishes, and improve skin elasticity. Indeed, studies suggest that neem oil’s antibacterial properties combat acne. A test-tube study showed that neem oil may aid long-term acne treatment when added to solid lipid nanoparticles (SLNs), a new type of drug formulation that offers a stable release of active ingredients. All the same, research in humans is necessary.  

6. Ulcer and Wound Healing

  Animal studies suggest that neem leaf extract accelerates wound healing through an increased inflammatory response and the formation of new blood vessels. In a 2013, 34-day case study, applying 100 mg of neem oil topically twice daily completely healed chronic skin ulcers. In another study, 6 people with intestinal ulcers took 30 mg of neem extract orally twice daily. After 10 days, acid secretion had declined significantly, and after 10 weeks, the ulcers were almost completely healed. Yet, this was a fairly small study. More human research is needed.
