Tamarind

Tamarind contains ingredients that might have laxative effects and fight against certain fungi and bacteria. It also contains a chemical that is similar to mucin found in the eye. Mucin helps protect and wet the surface of the cornea.

People use tamarind for dry eye, constipation, parasite infections, early orgasm (premature ejaculation), and many other conditions, but there is no good scientific evidence to support most of these uses.
