St. John’s wort

St. John’s wort is a plant that’s native to Europe, western Asia, and northern Africa. Europeans commonly take St. John’s wort as a way to treat depression, but the FDA hasn’t approved the herb to treat this condition.

Taking St. John’s wort has been linked with increasing the amount of serotonin in the body. Serotonin is a feel-good chemical in the brain that people with depression are often low in. Several antidepressants work by increasing the amount of serotonin in the brain.

According to the National Institutes of Health (NIH), St. John’s wort may help milder forms of depression, although its effects haven’t been conclusively proven either way. A 2008 review of 29 studies on St. John’s wort found that the plant was just as effective for treating mild to moderate depression as antidepressants, yet resulted in fewer side effects. On the other hand, the NIH’s National Center for Complementary and Integrative Health sponsored two separate studies that found it wasn’t better than a placebo for treating depression.

It’s important to note that St. John’s wort is known for interacting with lots of medications. This is especially true for blood thinners, birth control pills, and chemotherapy medications. Always check with your doctor before taking this herb.
