Herb-drug interactions ginger

At least a dozen different herbs are used to ease the symptoms of rheumatoid arthritis most are considered to be anti-inflammatories. Herbs that have been tried include powdered ginger, borage seed oil, or devil s claw to reduce pain and swelling. Stinging nettles or turmeric also may lessen pain, stiffness, and inflammation. Because these herbs can interact with each other or with prescription comedications, lack of careful studies means that little is known about long-term effects and drug interactions.
