What healing power is in St. John's wort?

The St. John's wort (Hypericum perforatum) has a mild antidepressant effect. Its use in mild to moderate depressive episodes is therefore medically recognized. However, St. John's wort must be taken in high doses, so that it can work, so in the form of appropriately dosed finished medicinal products.

Based on many years of experience, the medicinal plant can also be used internally for temporary mental fatigue and mild gastrointestinal complaints as well as externally (for example in the form of St. John's Wort oil) in case of mild skin inflammation (such as sunburn) and light wounds.

The antidepressant effect of the medicinal plant is mainly attributed to the hyperforin ingredient. Other ingredients (such as hyperoside, etc.) may contribute to this effect, but this needs to be further explored.

Oily preparations of St. John's wort (such as St. John's wort oil) have an anti-inflammatory effect.

How is St. John's wort used?

The medicinal plant is available in various forms - as a cut herb for tea preparation, as a dry extract in St. John's wort capsules, pills, tablets, droplets, as an alcoholic extract (in the form of drops, etc.), as fresh plant juice and as St. John's wort -Oil. The latter is called red oil because of its color.

For the preparation of St. John's wort preparations, the dried flowering branch tips with flowers, leaves and stems (Hyperici herba) are used. Especially for use as a herbal antidepressant, standardized finished medicinal products should be used. The dosage, method and duration of use can be found in the respective package leaflets and by the doctor or pharmacist.

The use of a self-produced St. John's Wort tea is not recommended.

You can also make St. John's wort oil for external use by adding freshly flowered blossoms to a light screw-top jar and filling with a cold pressed olive oil of good quality until the flowers are about a fingerbreit covered with it. Then screw the glass and place it in a light or sunny place for four to five weeks. In between you should shake the glass every now and then. At the end, peel off the flowers and pour the oil into a dark bottle for storage. During use, you can moisten your palm with it and rub it on the affected skin area.

Like chemical antidepressants, St. John's Wort can cause side effects, but less frequently. Nevertheless, there are serious warnings that you should consider before taking:

Worth knowing about St. John's wort

St. John's wort (or St. John's wort, Hypericum perforatum) belongs to the family of St. John's wort plants (Hypericaceae). It is native to Europe, West Asia, the Canary Islands and North Africa and naturalized in many other regions.

The genus name is derived from the Greek ("hyper" and "ereikon" = growing on the heath) and probably describes the preferred locations of up to about 80 centimeters high St. John's wort plant - dry soils on heaths and dry grasslands, on embankments, trail and roadsides.

The plant received the Latin name "perforatum" and the German name "Spotted St. John's wort" because of its dotted (Latin: perforatum = pierced) leaves: If one - in pairs on the branches opposite (ie oppositely arranged) - elliptic, smooth-edged leaves holding against the light, you see bright spots on the leaf surface. These are oil glands that contain essential oil. The summer solstice also plays a role in the German naming because the plant starts to bloom around the so-called Johanni day on June 24th.

From June until late summer, the true St. John's wort bears a lot of yellow flowers in racemose globules at the end of the hard, branched stems. Striking are the many long stamens that protrude from the flowers. The petals are like the leaves glandular dotted: Due to the contained dark red hypericin the oil glands appear as black dots on the petals. If you rub the flowers of the real St. John's Wort between the fingers, they turn red.
