Because Raynaud's phenomenon is hard to treat, many people try alternative medicine. We found one summary of the research into alternative treatments for Raynaud's. The study looked at acupuncture, antioxidant supplements, biofeedback, essential fatty acid supplements, Ginkgo biloba, L-arginine supplements, laser treatment, glucosaminoglycans supplements, and therapeutic gloves.
The summary said most of the studies looking at these treatments were old, small, and of poor quality. The authors said it is hard to draw conclusions from the studies, except to say that the research shows that biofeedback does not work. 
If you have acupuncture, an acupuncturist puts thin, sterile needles into your skin. People who perform traditional acupuncture believe that it removes blockages along energy channels in your body. Other acupuncturists say that the needles help your body release natural chemicals that block pain.
When you have biofeedback, your doctor helps you use a device that measures how fast your heart beats, how fast you're breathing or how tense your muscles are. The information you get from the device is called 'biofeedback'. Biofeedback lets you see how your heartbeat, breathing or muscle tension change when you do things like stand or sit differently, or slow down your breathing. The idea is that you can learn to sense the messages from your body without the device and learn how to control the way you respond to stress.
