St John's Wort

What is St John's wort?

St John's wort, or hypericum, has been used for centuries to treat problems such as anxiety, tension, insomnia and depression. The medicinal herb, extracted from bright golden-yellow, star-shaped flowers, is often recommended for menopausal problems, stomach ulcers, chronic pain conditions and viral infections.

How can it help me?

While the research into St John's wort is mixed, it appears that it is as effective as modern synthetic antidepressant drugs, and it seems to have fewer side-effects.  (See St John’s Wort, Background Research on this website for more information) . In some European countries, it's the most popular treatment for depression.

What are the potential risks?

Always consult your GP before taking St John’s Wort.  It can cause light sensitivity, and you should not take it if you are taking warfarin, cyclosporin, oral contraceptives, anticonvulsants, digoxin, theophylline or certain anti-HIV drugs, as it may reduce the effect of these medicines.  It is important
to keep to the recommended dosage.
You should not take it at the same time as taking an SSRI antidepressant or triptan medicines, or if you are pregnant or breastfeeding.

Where can I get it?

St John’s Wort is widely available from chemists, health food stores and supermarkets. Look for a reputable brand containing a standardised extract and a recommended daily dosage of 300mg
