Curcumin is a beloved molecule among middle easterners and others, including westerners who attribute all sorts of disease fighting ability to it.
It’s an interesting molecule but doesn’t make a very good drug and it’s effects are quite exaggerated beyond any solid data.
It would be great if all the things attributed to it were true.
As it is, I think it’s a fine supplement to take or to get in eating curry or other food with it.
But it’s not a wonder drug.
Curcumin supposedly relieves inflammation, other medical conditions.
Research also going on at Oregon State U. Quite a lot of info about it here:

Just to be on the side of the angels, I use as much turmeric in cooking as I can stand. It’s rather an acquired taste. Easier to acquire if I dump in red pepper in one form or another. Tabasco. Sriracha. Gringo Bandito sauce, etc.
