Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog is intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    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.
