7. St. John’s Wort
St. John’s wort has been used as a medicinal herb for its antidepressant and anti-inflammatory properties for over 2,000 years. It produces dozens of biologically active substances, but hypericin and hyperforin have the greatest medical activity. St. John’s wort uses come from its antidepressant activity, ability to relieve PMS symptoms, improve mood during menopause, fight inflammation, relieve skin irritations and improve symptoms of obsessive compulsive disorder.
A study done at the Institute of Psychological Sciences in the United Kingdom included 36 women aged 18–45 who experienced regular menstrual cycles and were diagnosed with mild PMS. The women were randomly assigned to receive either St. John’s wort tablets at 900 milligrams a day or identical placebo tablets for two menstrual cycles; then the groups switched doses for the next two cycles. Symptoms were rated daily throughout the study, and the women reported on feelings of depression, aggression, hormone balance and hormonal stimulation. The trials showed that St. John’s wort was superior to a placebo in improving physical and behavioral symptoms of PMS. (12)
8. Ginkgo Biloba
Ginkgo biloba, which is also known as maidenhair, is an ancient plant extract that has been used in Traditional Chinese Medicine to heal various health ailments for thousands of years. Current research shows that it’s linked to improvements in cognitive function. When researchers from Beijing University of Chinese Medicine reviewed evidence from 14 randomized controlled trials involving brain injury patients, it reported that ginkgo biloba extract had positive effects on patients’ neurological impairment and quality of life in nine of the trials.
