Products made from botanicals, or plants, that are used to treat diseases or to maintain health are called herbal products, botanical products, or phytomedicines. Herbal supplements are products made from plants for internal use. According to the 1994 Dietary Supplement Health and Education Act, a dietary supplement is "intended to supplement the diet; contains one or more dietary ingredients or their constituents; is intended to be taken by mouth as a pill, capsule, tablet, or liquid; and is labeled as being a dietary supplement."
Many prescription drugs and over-the-counter medications also are made from plant derivatives, but these products contain only purified ingredients and are regulated by the FDA. Herbal supplements may contain entire plants or plant parts.
Herbal supplements come in all forms: dried, chopped, powdered, capsule, or liquid, and can be used in various ways, including:
Swallowed as pills
Brewed as tea
Applied to the skin as gels
Added to bath water
The practice of using herbal supplements dates back thousands of years. Today, there is a resurgence in the use of herbal supplements among American consumers. However, herbal supplements are not for everyone. Because they are not subject to close scrutiny by the FDA, or other governing agencies, the use of herbal supplements remains controversial. It is best to consult your doctor about any symptoms or conditions you are experiencing and to discuss the use of herbal supplements.
Herbal supplements are considered foods, not drugs, by the FDA and, therefore, are not subject to the same testing, manufacturing, and labeling standards and regulations as drugs.
Until 1994, the FDA had disallowed health claims of any kind on herbal supplements. The passage of the federal Dietary Supplement and Health Education Act (DSHEA) in late 1994 started to reverse this trend.
In January 2000, the FDA updated the laws governing the labeling of herbal supplements, so consumers now can see labels that explain how herbs can influence different actions in the body. However, herbal supplement labels still cannot say anything about treating specific medical conditions, because herbal supplements are not subject to clinical trials or to the same manufacturing standards as prescription or traditional over-the-counter drugs.
For example, St. John's wort is a popular herbal supplement thought to be useful for treating depression in some cases. A product label on St. John's wort might say, "enhances mood," but it cannot, according to FDA regulations, lay claim to treating a specific condition, because the product has not been subject to the extensive clinical testing of FDA-approved medications.
Dietary supplements, unlike medications, are not required to be standardized to ensure batch-to-batch consistency. Some manufacturers may use the word standardized on a supplement label, but it does not necessarily mean the same thing from one manufacturer to the next because there is no legal definition of the term.
Herbal medications can interact with conventional medicines or have strong effects. Do not self-diagnose. Consult your doctor before taking herbal supplements.
Educate yourself. Learn as much as you can about the herbs you are taking by consulting your doctor and contacting herbal supplement manufacturers for information.
If you use herbal supplements, follow label instructions carefully and use the prescribed dosage only. Never exceed the recommended dosage, and seek out information about contraindications.
Watch for side effects. If symptoms, such as nausea, dizziness, headache, or upset stomach, occur, reduce the dosage or stop taking the herbal supplement.
Be alert for allergic reactions. A severe allergic reaction can cause difficulty breathing. If such a problem occurs, call 911 or the emergency number in your area for help.
Research the company whose herbs you are taking. All herbal supplements are not created equal, and it is best to choose a reputable manufacturer's brand. Ask yourself:
Is the manufacturer involved in researching its own herbal products or simply relying on the research efforts of others?
Does the product make outlandish or hard-to-prove claims?
Does the product label give information about the standardized formula, side effects, ingredients, directions, and precautions?
Is label information clear and easy to read?
Is there a toll-free telephone number, an address, or a website address listed so consumers can find out more information about the product?
The following list of common herbal supplements is for informational purposes only. Consult your doctor to discuss specific medical conditions or symptoms that you might be experiencing. Do not self-diagnose, and consult your doctor before taking any herbal supplements.

Consult your doctor about symptoms you are experiencing and discuss herbal supplements before beginning use.
