Thousands of Years of Use
Devil’s claw (Harpagophytum procumbens), also known as “grapple plant” because of its claw-like dried seed pods, is an herb from the Kalahari desert region of southwestern Africa.
The tubers from the plant have been used in traditional African medicine for thousands of years for a wide variety of disorders. Modern research in Europe has shown it reduces inflammation and pain in rheumatic conditions, alleviating pain in joints, helps digestive disorders and can stimulate appetite.
An Approved Pain Killer. Devil’s claw is approved as a
non-prescription medicine by the German Commission E,
an expert panel of physicians and pharmacists who advise
Germany’s counterpart of the U.S. Food and Drug
Administration. Approved uses of devil’s claw include loss
of appetite, digestive disorders, and degenerative disorders
of the locomotor system (i.e., to treat pain and inflammation
in the joints).
One clinical study (2000) showed that this traditional
African medicinal herb, devil’s claw, may reduce pain
associated with osteoarthritis as effectively as some conventional drugs. In a randomized, double-blind, parallel
group study conducted in France, the patients who suffered
from osteoarthritis of the knee and hip received either devil’s
claw capsules or a pharmaceutical drug (diacerhein) for
pain.
Pain relief parameters of all patients indicated that those
who took devil’s claw or the drug experienced similar
benefits for pain relief. However, the study also showed
that patients taking devil’s claw experienced significantly
fewer adverse side effects than those taking the drug. The
clinical study was published in Phytomedicine, a leading
European journal dealing with scientific research on herbs
and phytomedicinal products. |
According to Mark Blumenthal, director of the American
Botanical Council, “At least two previous clinical trials on
devil’s claw have supported its use as an aid in treating
lower back pain and rheumatic conditions. This study is
significant in that it is the first to show the potential benefits
of devil’s claw for osteoarthritis.”
He added, “Although
more research is warranted, this may be good news to people who suffer from osteoarthritis, as well as their physicians,
whose therapeutic choices have been fairly limited.”
Research Summary
• In a randomized, double-blind study, devil’s claw was
shown to be as effective in eliminating pain from osteoporosis as a conventional medical drug for pain
(with no adverse side effects).
• Devil’s claw helped relieve arthritis-related symptoms in
630 people with degenerative joint disease. These
people took devil’s claw daily (3 to 9 g) for 6 months.
Depending on the location of the arthritis, from 42% to
85% of the people showed improvements in their
symptoms. No side effects other than mild stomach upset
were reported.1
• Researchers gave people with joint pain either devil’s
claw (2.3 g) or an inactive placebo daily for 3 to 9 weeks.
People taking the devil’s claw reported a significant
decrease in pain and positive results compared to those
taking the placebo.1
• Researchers gave devil’s claw or a placebo to 89 people
with joint pain and inflammation. After 2 months, those
who took devil’s claw each day (2 g) reported less pain
and greater mobility than those who took the placebo.1
