Throughout Southeast Asia neem has been used successfully by herbalists for hundreds of years to reduce tumors. Researchers are now supporting these uses.

Neem has been tested on many types of cancers, such as skin cancers, using neem-based creams and lymphocytic cancer, using the herb internally. In India, Europe and Japan scientists have found that polysaccharides and liminoids in neem bark, leaves and seed oil reduced tumors and cancers and were effective against lymphocytic leukemia.

In Japan, several issued patents included hot water neem bark extracts; these were effective against several types of cancer. Several extracts were tested at different doses and were compared to standard anticancer agents. Many extracts were equal or better than the standard treatments against solid tumors. Results of tests performed with a more purified extract of the bark produced even better results. Further studies using pure active compounds are hoped to produce even more impressive results.

In another study, one researcher used an extract of neem leaves to prevent the adhesion of cancer cells to other body cells. If cancers can’t stick to other cells, the cancer can’t spread throughout the body and is more easily destroyed.

Neem’s success has been noticeably remarkable with skin cancers. A number of reports have been made by patients that their skin cancers have disappeared after several months of using a neem-based cream on a daily basis. Injections of neem extract around various tumors have shown sizable reduction in a few weeks’ time.
