The American College of Physicians (ACP) reports major depressive disorder (MDD) is the most prevalent depressive disorder in the United States, with an estimated lifetime prevalence of 16 percent.
St John's wort is today most widely known as a herbal treatment for depression. In some countries, such as Germany, it is commonly prescribed for mild depression, especially in children, adolescents, and where cost is a concern. Standardized extracts are generally available over the counter — however, in some countries (such as Ireland) a prescription is required. Extracts are usually in tablet or capsule form, and also in teabags and tinctures.
