Herbs and Supplements

Manufacturers of herbal remedies and dietary supplements do not need Food and Drug Administration approval to sell their products. Just like a drug, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been several reported cases of serious and even lethal side effects from herbal products. Patients should always check with their doctors before using any herbal remedies or dietary supplements.

Riboflavin (Vitamin B2). Some studies have found that people who take vitamin B2 experience a reduction in the frequency of migraine attacks (although not on duration or severity). Vitamin B2 is generally safe, although some people taking high doses develop diarrhea.

Magnesium Supplements. Some studies have reported a higher rate of magnesium deficiencies in some patients with migraine, such as those with menstrual migraines. Magnesium helps relax blood vessels. Some patients report that magnesium supplements help provide relief.

Feverfew. Feverfew is the most studied herbal remedy for headaches and may help in some cases. However, like all effective headache remedies, overuse can cause a rebound effect.

Fish Oil. Some studies suggest that omega-3 fatty acids, which are found in fish oil, have anti-inflammatory and nerve protecting actions. These fatty acids can be found in oily fish, such as salmon, mackerel, or sardines. They can also be obtained in supplements of specific omega-3 compounds (DHA-EPA).

Ginger. In general, herbal medicines should never be used by children or pregnant or nursing women without medical counsel. One exception may be ginger, which has no side effects and can be eaten or taken as a tea in powder or fresh form, as long as quantities are not excessive. Some people have reported less pain and frequency of migraines while taking ginger, and children can take it without danger. Ginger is also a popular home remedy for relieving nausea.
