St John's Wort Herb Profile

Also known as- Hypericum perforatum, Perforated bush, Hypericum, and Klamath weed.

Introduction

Who doesn't know all about St. John's wort? This lanky herbaceous plant with yellow flowers filled with 50 to 60 stamens is the best selling medicinal herb in the United States and much of the rest of the world. The original uses of this versatile plant, however, were treating bedwetting, rheumatism, and gout. A St. John's wort oil made with the blossoms and olive, sunflower, or, preferably, wheat germ oil has been used for centuries for treating wounds and burns.

Constituents

Hypericin and related compounds, rutin, bitters, and tannins.

Parts Used

The dried flowering tops and leaf.

Typical Preparations

Traditionally used as a tea, sometimes available in tea bags; also used to make a red St. John's oil for use in liniments and lotions, but only from fresh material. May also be administered as a capsule or extract for convenience.

Summary

A large volume of scientific research suggests that only a standardized extract delivering a rather high dose of the hypericin found in St. John's wort treats depression"so how can the successful use of the much milder traditional teas of St. John's wort to treat depression be explained?
St. John's wort as a whole herb gives the body "just enough medicine" to overcome the physical aches and pains and mild viral infections that keep the brain from recovering from depression. Nineteenth century Eclectic physicians in the United States used St. John's wort to relieve pain caused by injuries to the spine and puncture wounds in the hands and feet. The herb was noted for its ability to slow frequent urination, and treat "throbbing pains" of any origin.

Precautions

St. John's wort extracts may increase sensitivity to sunlight and risk of sunburn, but this is extremely rare when the whole herb is used. Not to be used with a MAO or Protease inhibitor.
