Eating ginger/turmeric/cinnamon can interfere with prescription medication

I would take this study with a pinch of salt, no pun intended. Ginger, turmeric, cinnamon and other such spices and herbs may interfere or not.

But these studies swing based upon who is sponsoring those studies.

At one time, there were studies that cigarettes are good for health, then wine is good for health, moderate amounts of alcohol is good for health, coffee is good for health, eggs are good for health - and then all of those are bad for health in later / other studies.
