My doctor told me they investigate these natural herbs, and they almost always turn out to be of little or no value. But Turmeric is an exception. He said they found it far outperforms the claims made by its proponents.
You have to take other vitamins with Turmeric to avoid any allergic reactions
I am not sure what, exactly, but I take a lot of zinc magnesium vitamin B complex LOTS of vitamin D and some other things
I haven’ figured out what stops the allergic reaction but I can eat turmeric again.
The best turmeric, according to ConsumerLab.com, was Doctor’s Best C3 Complex Curcumin.
