CAM for Raynaud’s phenomenon?
The value of conventional treatment is limited, and so is CAM.
Let’s review.
Raynaud’s (say “ray-NOHZ”) phenomenon is a condition in which blood flow to the surface tissue of the hands and feet is temporarily decreased, usually as an overresponse to cold temperatures.
First, the details.
- Researchers from Canada searched the literature and found 20 studies.
- Acupuncture (2)
- Anti-oxidants (2)
- Biofeedback (5)
- Essential fatty acids (3)
- Ginkgo biloba (1)
- L-arginine (2)
- Laser (3)
- Glucosaminoglycans (1)
- Therapeutic gloves (1)
And, the results.
- Most studies were negative, of poor quality, and done prior to 1990.
- Biofeedback: negative for a change in frequency, duration, and severity of Raynoud’s attacks.
- The results actually favored sham biofeedback.
- The therapeutic glove: effective.
- Laser: an average of 1 less Raynaud’s attack over 2 weeks vs sham and a change in severity of attacks.
- Nutritional supplements: no change.
The bottom line?
There’s a need for well-designed studies of CAM in Raynaud’s phenomenon.
