Nature's Drugs
Feverfew for migraines, garlic for heart disease, St. John's wort for depression. These are just a few of the many "natural" substances ingested by millions of Americans to treat a variety of health conditions. The use of so-called alternative medicines is widespread, but you may be surprised to learn that researchers do not know in most cases how herbs work - or if they work at all - inside the human body.
Herbs are not regulated by the Food and Drug Administration, and scientists have not performed careful studies to evaluate their safety and effectiveness. Unlike many prescription (or even over-the-counter) medicines, herbs contain many - sometimes thousands - of ingredients. While some small studies have confirmed the usefulness of certain herbs, like feverfew, other herbal products have proved ineffective or harmful. For example, recent studies suggest that St. John's wort is of no benefit in treating major depression. What's more, because herbs are complicated concoctions containing many active components, they can interfere with the body's metabolism of other drugs, such as certain HIV treatments and birth control pills.

Before taking an herb or a botanical preparation, consult a doctor or other health care provider, especially if you have a disease or medical condition, take any medications, are pregnant or nursing, or are planning to have an operation. Statements made about dietary supplements have not been evaluated by the Food and Drug Administration (FDA). Dietary supplements do not require FDA approval to be sold in the United States.
