An 18-year-old college student is taking herbal remedies for migraines. Which herbal remedy is commonly used for this purpose?

Feverfew is widely recognized for its effectiveness in the prevention and treatment of migraines. This herbal remedy contains active compounds that can help reduce the frequency and severity of migraine headaches. The use of feverfew is supported by various studies indicating its efficacy in migraine prevention, making it a popular choice among individuals seeking alternative therapies for this condition.

In contrast, while echinacea is primarily used to enhance the immune system, particularly in the prevention of colds and other upper respiratory infections, it is not associated with migraine treatment. St. John's Wort is mainly used for depression and mood disorders and does not have a strong connection to migraine management. Ginkgo biloba is often used to improve cognitive function and enhance circulation but lacks evidence for effectively treating migraines. Therefore, feverfew stands out as the herb that specifically targets migraine relief among the choices provided.
