Tamarind is a hardwood tree known scientifically as Tamarindus indica. Its partially dried fruit is used to make medicine. In foods and beverages, tamarind is used as flavoring. It is also widely used in Asian cooking for chutneys and curries.Tamarind contains ingredients that might have laxative effects and some activity against certain fungi and bacteria.
Researchers are studying tamarind as a possible treatment for dry eyes because it contains a chemical that is similar to mucin found in the eye. Mucin helps protect and wet the surface of the cornea.
