Patients over age 50 typically present with one chronic disease per decade. Each chronic disease usually requires long-term drug therapy, meaning most older patients require several drugs to control their conditions and/or maintain their health. Simultaneously, the use of complementary and alternative medications (CAM) has increased in the United States over the last 20 years, reaching 36% in 2002; herbal medicine use accounts for approximately 22% of all CAM use. Older adults often add herbal medicines to medications prescribed by their physicians, yet do not always inform the physician.
