Devilís claw extract was found in one trial to reduce pain associated
with osteoarthritis as effectively as the slow-acting
analgesic/cartilage-protective drug diacerhein.

extract three times daily
Devilís claw has anti-inflammatory and analgesic actions and is a
traditional herbal remedy for people with rheumatoid arthritis.
How It Works
The devilís claw tuber contains three important constituents belonging
to the iridoid glycoside family: harpagoside, harpagide, and
procumbide. The secondary tubers of the herb contain twice as much
harpagoside as the primary tubers and are the chief source of devilís
claw used medicinally. Harpagoside and other iridoid glycosides found in
the plant may be responsible for the herbís anti-inflammatory and
analgesic actions. However, research has not entirely supported the use
of devilís claw in alleviating arthritic pain symptoms. In one trial it
was found to reduce pain associated with osteoarthritis as effectively
as the slow-acting analgesic/cartilage-protective drug diacerhein. One
double-blind study reported that devilís claw (600 or 1,200 mg per day)
was helpful in reducing low back pain.
Devilís claw is also considered by herbalists to be a potent bitter.
Bitter principles, like the iridoid glycosides found in devilís claw,
can be used in combination with carminative (gas-relieving) herbs by
people with indigestion, but not heartburn.
How to Use It
As a digestive stimulant, 1.5 to 2 grams per day of the powdered
secondary tuber are used. For tincture, the recommended amount is 1 to 2
ml three times daily. For osteoarthritis and rheumatoid arthritis, 4.5
to 10 grams of powder are used per day. Alternatively, standardized
extracts, 1,200 to 2,500 mg per day, may be taken.
Since devilís claw promotes the secretion of stomach acid, anyone with
gastric or duodenal ulcers, heartburn, gastritis, or excessive stomach
acid should not use the herb. Additionally, people with gallstones
should consult a physician before taking devilís claw.
