圣约翰草（Hypericum perforatum）

St. John's wort (Hypericum perforatum) is well known for its antidepressant effects.圣约翰草（Hypericum perforatum）以其抗抑郁作用而闻名。 In general, most studies have shown that St. John's wort may be an effective treatment for mild to moderate depression, and has fewer side effects than most other prescription antidepressants.总的来说，大多数研究表明，圣约翰草可能是轻度至中度抑郁症的有效治疗方法，且副作用比大多数其他处方抗抑郁药少。 But the herb interacts with a wide variety of medications, including birth control pills, so it is important to take it only under the guidance of a health care provider.但是这种草药会与多种药物（包括避孕药）发生相互作用，因此仅在医疗保健提供者的指导下服用该草药很重要。
