Best
for Rheumatoid Arthritis
Cat’s claw (Uncaria
tomentosa)
What
it is: The bark and root of a South
American vine.
How it
works: Cat’s claw is an
anti-inflammatory that inhibits tumor necrosis factor (TNF), a target of
powerful RA drugs. It also contains
compounds that may benefit the immune system.
Studies: A small 2002 trial showed that it reduced
joint pain and swelling by more than 50 percent compared with placebo.
How
much: Capsule, tablet, tea extract: 60 mg daily in divided doses. Look for a brand that is free of tetracyclic
oxindole alkaloids.
Fish oil
What
it is: Oil from cold-water fish such as
herring and salmon – a rich source of the omega-3 fatty acids EPA and DHA.
How it
works: Omega-3s block inflammatory
cytokines and prostaglandins, and are converted by the body into powerful
anti-inflammatory chemicals called resolvins.
Studies: EPA and DHA have been extensively studied for
RA and dozens of other inflammatory conditions.
A 2010 meta-analysis found that fish oil significantly decreased joint
tenderness and stiffness in RA patients and reduced or eliminated NSAID use.
How
much: Softgel, liquid: 3.8 grams EPA and 2 grams DHA daily for
RA. (Look for 85 percent to 90 percent
concentrations of omega-3s).
NOTE: Studies show fish oil also can relieve
symptoms of Osteoarthritis (OA), depression and Sjögren’s syndrome.
GLA (gamma linolenic acid)
What
it is: An omega-6 fatty acid found in
some plant-seed oils, including black currant, borage and evening primrose.
How it
works: The body converts GLA into
anti-inflammatory chemicals.
Studies: In a 2005 trial, 56 patients with active RA
showed significant improvement in joint pain, stiffness and grip strength after
six months and progressive improvement in control of disease activity at one
year. A smaller study found that a combination of evening primrose oil and fish
oil significantly reduced the need for conventional pain relievers.
How
much: Capsule, oil, softgel: 30 mg to 3 grams daily in divided doses or
450 mg GLA and 240 mg EPA daily.
Ginger (Zingiber officinale)
What
it is: The dried or fresh root of the
ginger plant.
How it
works: Used in Asian medicine for
centuries, ginger has been showed to have
anti-inflammatory properties similar to ibuprofen and COX-2 inhibitors. Ginger also suppresses leukotrienes
(inflammatory molecules) and switches off certain inflammatory genes, making it
oitentially more effective than conventional pain relievers.
Studies: In a 2012 in vitro study, a specialized
ginger extract called Eurovita Extract 77
reduced inflammatory reactions in a RA synovial cells as effectively as steroid
did.
How
much: Capsules, extract, tea: In studies, 255 mg of Eurovita Extract 77 twice daily.
NOTE: Several trials show ginger may help reduce OA pain.
