Medicinal uses

Because of its wound-healing properties, St John's wort has traditionally been used to treat burns and skin irritations. However, it has also been shown to have a positive effect on less serious cases of depression and today is now widely prescribed in Europe as a mild antidepressant.

Recently, the plant's mood-lifting properties have attracted considerable attention, and extensive clinical trials have been carried out to enable this use to be officially recognised. The mechanism by which the plant exerts its antidepressant action, however, remains unclear.

In vitro studies conducted in 1984 suggested that hypericin acted in a similar way to monoamine oxidase inhibitor antidepressants (more commonly known as MOAls). And German research published in 1998 documents the antidepressant activity of a substance in the plant, hyperforin, which appears to have a beneficial effect on serotonin activity in the brain.

St John's wort is also prescribed for depressive symptoms including nervous fatigue, negativity and sleeping difficulties.

Externally, St John's wort is recommended for minor burns and scalds and to ease neuralgia, sciatica and other painful inflammations.
