ABSTRACT
Extracts derived from herbs can be used in the manufacture of food sup-plements and fortied food. Food supplements are also known as dietary supplements or nutritional supplements. Some countries dene them as drugs, whereas others treat them as foods. According to the laws in force in the United States, Europe, Australia, and Japan, a food supplement cannot claim to prevent, treat, or cure any disease. Violation of these laws implies that the product in question is an unapproved or illegal drug. Despite this apparent constraint, wise physicians and the lay public in those countries make good use of these innocuous products. Food supplements are generally manufactured according to the principles of modern pharmaceutics, which uses various dosage forms to deliver the medicinal substances.
