History of St John’s wort
St John’s wort has been used as a remedy for nerve disorders for more than 2,000 years. It was popular in ancient Greece and Rome as a healing remedy for wounds, as well as sores, burns, bruises and nerve pains. It was also thought to ward off evil spirits and the insane would often drink an infusion of St John’s wort in an attempt to ward off madness.
Current uses of St John’s wort
LOW MOOD
At least 30 studies on more than 1,700 patients show that St John’s wort can be an effective remedy for mild- to-moderate depression without the side effects of more conventional anti-depressants. It is not known exactly how it works but it is thought to help prolong the action of the brain neurotransmitter serotonin – a deficiency of which can result in depression.
SAD (Seasonal Affective Disorder)
St John’s wort is often prescribed to help banish SAD, often called the winter blues – a condition bought on by the lack of sunlight that occurs in autumn and winter. In one study comparing St John’s wort to light therapy, the researchers concluded that St John’s wort was as effective as light therapy. They wrote that the herb ‘…brings light into dark places.’
SLEEP
St John’s wort can help to increase the production of the hormone melatonin (the brain’s natural sedative) to help improve the quality of sleep.
PMS (Pre-Menstrual Syndrome)
Many women report that taking St John’s wort for depression can help to relieve PMS symptoms. Similarly older women have found that it can relieve menopausal symptoms.
