Nature's Pharmacy: Do You Have a Green Tongue?

Article excerpt

Herbal medicine is one of the most ancient forms of health care known to humankind. The use of plants for healing purposes has been prevalent in all cultures throughout history and continues to playa role in medicine today. With an estimated 250,000 to 500,000 plants on earth today, approximately 25% of all prescription drugs are derived from these plants. (1) Over the past decade, there has been a widespread use of natural herbal medicine in lieu of the use of synthetic, prescription drugs due to the growing concern of side effects from such pharmaceutical drugs. In the United States, the annual retail sales of herbal products have skyrocketed from $200 million in 1988 to more than $5.1 billion in 1997.

While herbal medicine has much to offer, adverse effects can result from lack of quality control and standardization, consuming an inadequate dose, using the wrong herb, and reactions with modern drugs. (3,4) To promote safe health care consumerism, a thorough examination of the herbs that are among the most widely used natural medications in America is suggested. Health educators have the opportunity to initiate discussions and implement lessons regarding herbal medicine. This teaching strategy invites students to access credible information related to herbal medicine needed for its safe implementation into daily lives.
