Raynaud's syndrome, also referred to as Raynaud's disease, is a circulatory condition affecting the small blood vessels in the fingers, toes, ears and nose. These tiny vessels over-react to cold and stress by going into spasm, reducing blood flow. As a result, the affected areas feel cold and numb. At first, the toes and fingers appear pale, but they turn a dusky blue color and then redden as blood flow returns. There are a variety of prescription medications used for Raynaud's, but there are some herbal remedies available as well. Talk to your doctor about which is best for you.
Evening Primrose Oil
Evening primrose oil has been studied for use in the treatment of Raynaud's syndrome. In August 1985, "Thrombosis and Haemostasis" reported that while taking evening primrose oil reduced the occurrence and severity of symptoms, there was no noticeable improvement in blood flow. Evening primrose oil is extracted from the plant's seeds and is high in the essential fatty acids linoleic acid and gamma-linoleic acid, or GLA. Evening primrose oil can be taken as a capsule or oil. Side effects include headache, nausea and stomach upset. You should not take evening primrose oil if you have a bleeding disorder or seizure disorder, are taking nonsteroidal anti-inflammatory drugs or if you are pregnant. Check with your doctor to determine whether you would benefit from taking evening primrose oil.
Ginkgo Biloba
Ginkgo biloba is an herb that has been used as an herbal remedy for a variety of ailments for thousands of years. It is well-known for its use in memory enhancement and as a treatment for Alzheimer's disease. More studies are needed, but it may be effective in reducing the frequency of Raynaud's syndrome attacks. You should never take ginkgo biloba seeds, as they can be toxic. Allergic reactions are possible, particularly if you are sensitive to poison oak, poison ivy or cashews. Side effects include headache and nausea. Consult with your doctor first, especially if you have diabetes or a bleeding disorder.
Dong Quai
Dong quai root, or Angelica sinensis, is sometimes used to treat Raynaud's syndrome. In traditional Chinese medicine, it is used to improve circulation. Dong quai is related to celery, and its roots are used for medicinal purposes. Few human studies have been performed, but lab results show it is effective in dilating blood vessels. Do not take dong quai if you have chronic diarrhea or gas. Side effects include sensitivity to sunlight and skin rash. Consult your doctor before taking dong quai, especially if you are at risk for hormone-sensitive cancers, such as uterine, ovarian or breast cancer.
Cayenne
Cayenne is derived from red pepper and is used as both a spice and herbal remedy. Its active ingredient capsaicin has pain-relieving abilities and is also being studied for its ability to improve circulation. The fruit is dried and taken in capsule form for Raynaud's. Side effects include stomach upset and pain. Taking large doses can cause stomach ulcers and kidney and liver damage. If you are allergic to latex, kiwi, avocados or bananas, you may not be able to take cayenne. It interacts with some medications, including NSAIDs, blood thinners and stomach acid reducers. Get your doctor's OK before taking cayenne to treat your condition.
