St Johns Wort

About St Johns Wort

One of the most extensively studied herbal medicines - over 40 clinical trials confirm it is effective for mild to moderate depression, comparable to standard antidepressants. It was named because it blooms around St Johns Day (June 24). The flowers produce a red oil when steeped, containing hypericin. It has serious drug interactions - it induces liver enzymes that can reduce the effectiveness of birth control pills, blood thinners, and HIV medications. It can cause photosensitivity in light-skinned individuals. It is considered an invasive weed in many countries. It has been used since ancient Greece for nerve pain and wound healing.
