Why should I use herbal products?

The decision to use herbs to improve your health is, as with all health decisions, a personal one. There are, however, many good reasons to consider herbal products to  complement your own health care methods. One of the best reason, however, may be the fact that herbs and herbal products, continue to provide real health benefits while maintaining a remarkable safety profile. Readily available natural substances were the first medicines used by humans. Primitive and ancient civilizations as well as contemporary cultures throughout the world have always relied on herbs to provide the benefits that have been observed with their use. In fact, the World Health Organization has estimated that 80 percent of the world's population continues to use traditional therapies, a major part of which are derived from plants, as their primary health care tools. In our own time and culture, most herbs are available in the form of "herbal supplements." These products are found in the form of teas, tablets, capsules, liquid extracts, and others. We now have ready access to products that bring the herbal traditions from all over the world in a variety of convenient forms. In addition, scientific inquiries continue to develop our knowledge of the benefits of plants, and often validate the observations made over the past centuries.
