St. John’s wort is a shrub that is native to Europe and has been used for centuries to treat mental health conditions. Both the leaves and the yellow flowers of the plant contain active ingredients, such as hypericin and hyperforin, which are credited with giving it its medicinal qualities. Science is still exploring the potential benefits of St. John’s wort.
1. Treats depression
Perhaps its most common use, St. John’s wort is used as a natural antidepressant. Several studies have shown the plant to be as effective as certain prescription medications in treating mild to moderate depression. However, more research is still needed to support the use of St. John’s wort in treating severe depression.
Be sure to consult your doctor before taking St. John’s wort, and remember that, since there is no standard dose of St. John’s wort, strength and purity can vary between brands.
