Neem truly seems like miraculous natural drug. Neem has been shown to provide an antiviral treatment option for small-pox, chicken-pox, and warts. It is particularly useful for these conditions when applied directly to the skin. This is due in part to its ability to inhibit viruses from multiplying and spreading.

Chronic fatigue is considered to be caused by both viral and fungal infections. Neem, which can attack both, helps the body fight this debilitating syndrome.
Minor cuts, sprains and bruises are treated with neem lotion, cream or leaf extract applied locally. Its anti-inflammatory and antibacterial attributes are soothing to these conditions.

Hepatitis is another disease helped by neem. This often-deadly disease can be transmitted through blood or by ingesting contaminated food or water. Recent studies indicate that neem extracts can block infection by the virus that causes the disease.

Tests in Germany have shown that neem extracts are toxic to the herpes virus and can easily heal cold sores. Both a mild neem leaf tea and a tropical cream application are recommended. Once the eruption has peaked, discontinue the tea (taken after breakfast and after dinner0 and continue to apply cream until the sore has healed.

Chagas disease is a major health problem that infects some sixteen to eighteen million people, with another ninety million at risk in parts of South and Central America. It may be deadly. There is no vaccine and no safe and effective drug for its cure. The disease is caused by a parasite. Trypanosoma cruzi, which is spread by an insect, named the kissing bug.

Lab tests in Germany and Brazil have indicated that neem may be a solution. Neem leaf extracts have negative effects on these pernicious insects. Feeding neem or more specifically a single dose of Azadirachtin to the bugs not only eliminate the parasites, but the Azadirachtin prevents the young from molting and the adults from reproducing. Neem leaf or seed extracts may also be sprayed throughout the home where the kissing bug lives; this eliminates the parasites and prevents the bugs from laying eggs.

At the moment, scientists are researching the antibacterial and virus-reducing characteristics of the tree. The first studies confirm its effectiveness against selected fungi that occur, for example, on hair (trichophyton), skin and nails (epidermophyton), or in the vagina (candida).
