Please don't think just a handful of Cashews each day will prevent you from getting caries or cure your tuberculosis (which is by the way one of THE hardest bacterial infections to cure). It won't. The cashews wouldn't even get into your lungs for the tuberculosis. And don't even try to inhale them... you'll just start coughing a lot.

Feel free to add it to a real therapy or to eat them just because you think Cashews are tasty... but Cashews on their own won't cure you. If you really have tb go see a doctor, otherwise you're not only posing a thread to yourself but also to everyone else you meet.
