Herbal medicine, also known as herbalism or botanical medicine, is a medical system based on the use of plants or plant extracts that may be eaten or applied to the skin. Since ancient times, herbal medicine has been used by many different cultures throughout the world to treat illness and to assist bodily functions. Herbal remedies in the form of extracts, tinctures, capsules and tablets as well as teas may be recommended by healthcare practitioners of many different disciplines as a practical way to address a wide variety of medical conditions.
Herbal medicine blurs the line between foods and medicines — a line that, in many cultures, was never drawn in the first place. Using herbs and spices that have a disease-preventive effect in foods is one of the best ways to take advantage of their healing power. For example, it appears that the daily use of the spice turmeric in curry dishes is one reason elderly people in India have one of the lowest rates of Alzheimer’s disease in the world.
