Hello,
Yes, I did try it BEFORE diagnosis in an effort to find some relief from the terrible pain I had. It was mildly effective but in reality I had to take the higher doses which made it pretty expensive.
Even if it is herbal, I would still check with your doctor that you can take it. The only warning I could find was for people with duodenal ulcers but even so, it is best to check as some of the herbal remedies can have a "draining" action (aimed at detoxifying our system) which can give extra work to kidneys and therefore not recommended.
It is also called Harpagophytum (for those not in an English speaking country).
