St. John's Wort

Scientific Name: Hypericum perforatum

St. John's Wort Information

St. John's wort (Hypericum perforatum), once thought to rid the body of evil spirits, has a history of medicinal use dating back to ancient Greece, where it was used to treat a range of illnesses, including various 'nervous conditions.' St. John's wort also has antibacterial and antiviral properties and, because of its anti-inflammatory properties, has been used to help heal wounds and burns. In recent years, there has been renewed interest in St. John's wort as a treatment for depression and there has been a great deal of scientific research on this topic. St. John's wort is one of the most commonly purchased herbal products in the United States. Because St. John's wort interacts with a wide variety of medications, it is important to take it only under the guidance of a healthcare provider who is knowledgeable about herbal medicines.

St. John's Wort Benefits

  • Effective in reducing depressive symptoms in those with mild to moderate but not severe (called major) depression
  • Equally effective as tricyclic anti-depressants (medication frequently prescribed for this condition) such as imipramine, amitriptyline, doxepin, desipramine, and nortriptyline, but has fewer side effects
  • Helps substantially reduce the craving for and intake of alcohol
  • Has demonstrated the ability to fight certain infections, including some bacteria that are resistant to the effects of antibiotics
  • May be useful in relieving both physical and emotional symptoms of PMS including cramps, irritability, food cravings, and breast tenderness
  • May help improve mood in those suffering from SAD (a form of depression that occurs during the winter months because of lack of sunlight)

St. John's Wort Nutrient Content

The best-studied active components are hypericin and pseudohypericin, found in both the leaves and flowers. There has been recent research to suggest, though, that these best-studied components may not be the most active in the plant, which also contains essential oils and flavonoids.

St. John's Wort Notes

The Dietary Supplement Information Bureau recommends a daily dosage of approximately 300mg (standardized extract), 3 times a day for optimal health. Many people take St. John's wort for depression. It is important to bear in mind that depression can be a serious condition and may be accompanied by thoughts of suicide or homicide, both of which warrant immediate medical attention. Evaluation by a healthcare professional should always be sought before using St. John's wort.
