I have joint pain, and hypertension, and high cholesterol. I was given a suggestion to try a supplement called Devils Claw. It seems to be a hopeful option. However, I also have occasional PVC s and was wondering if this could worsen them? The WebMD site suggests that some heart disorders can be affected. Also, in combo with my BP meds could my BP go too low? If you are unsure do you know of a resource I could find that might help me find an answer. I m not sure my primary Dr. is well versed with supplements or alternative therapies. Thank you in advance, Tom
