Raynaud's phenomenon is a little understood condition in which the fingers and toes show an exaggerated sensitivity to cold. Classic cases show a characteristic white, blue, and red color sequence as the digits lose blood supply and then rewarm. Some people develop only one or two of these signs.
The cause of Raynaud's phenomenon is unknown. It can occur by itself, as primary Raynaudís (also called Raynaudís disease), or as a consequence of other illnesses, such as scleroderma . In the latter case, it is called secondary Raynaudís.
Conventional treatment consists mainly of reassurance and the recommendation to avoid exposure to cold and the use of tobacco (which can worsen Raynaud's). In severe cases, a variety of drugs can be tried.
Proposed Natural Treatments
Preliminary evidence supports the use of several natural supplements in the treatment of Raynaudís phenomenon. Most of the positive evidence regards primary Raynaudís.
In a 17-week, double-blind, placebo-controlled trial of 35 people with Raynaudís, fish oil (taken at a dose that provided a total of 3.96 g of EPA and 2.64 g of DHA daily) reduced reaction to cold among those with primary Raynaudís disease, but did not seem to help those with Raynaudís caused by other illnesses. 2
The herb Ginkgo biloba has been found to increase circulation in the fingertips 6 and thus has been proposed as a treatment for Raynaudís. A 10-week, double-blind, placebo-controlled trial of 22 people with primary Raynaudís found that use of ginkgo at the very high dose of 120 mg 3 times daily reduced the number of Raynaudís attacks. 8
