A dangerous disease, hepatitis can be transmitted through blood or by ingesting contaminated food or water. Studies have indicated that neem extracts can block infection by the virus that causes it (Unander, 1992).
Prevention is recommended by drinking neem leaf tea after eating shellfish and after swimming in or drinking water potentially contaminated with sewage.
Viral hepatitis is a deadly disease with no effective remedy. Indian tests indicate that as much as 80% of the test cases showed significant improvement when treated with neem. (Wagh, 1988)
