Feb. 10, 2000 (Atlanta) -- The FDA on Thursday warned physicians that St. John's wort, a commonly used herbal remedy, dangerously interferes with a long list of prescription drugs. The action comes after two reports in the British medical journal The Lancet linking the herb to heart-transplant rejection and to HIV drug failure. The FDA warning goes far beyond these two drugs. Because the herb appears to interfere with the way the body processes many drugs, the FDA advises physicians against using St. John's wort (also known as Hypericum perforatum) with a long list of medications. These include a wide range of drugs used to treat conditions such as HIV infection, heart disease, seizure, high blood pressure, and cancer. levitra and cialis viagra websites selling viagra cialis overnight express mail best way to use viagra gran via viagra
