I'll go along with Turmeric, although I'm not so sure you have to be quite so specific in what you buy.
Also good for liver, kidney, gall bladder, are Reishi Mushroom and Milk Thistle capsules.
I also like an antiinflammatory tea, made up of equal parts Meadowsweet, Chamomile, and Agrimony.
Make this up one heaping tablespoon of each to a quart of boiling water and steep at least 15 minutes, then refrigerate. (you can steep overnight in the fridge if you like.)
Drink throughout the day.
None of these will interfere w/ bp meds.
