St. john's wort extract benefits：
Of the known usages for St. john's wort extract, depression is the most widely studied and the most commonly cited. “Patients with mild depression have been shown to benefit significantly more than placebo and [St. John’s wort is] as effective as standard antidepressants,” says Erin Nance, MD, a New York City–based orthopedic surgeon, citing the Cochrane Review’s systematic review on the subject, which is considered to be one of the most comprehensive. While the clinical trials for treating mild depression indicate positive results, when it comes to treating moderate depression, major depressive disorder, severe depression, or bipolar disorder, St. John’s wort is not a recommended treatment.
The hyperforin found in St. John’s wort acts on chemical messengers in the brain that can affect mood to treat mild depression, similar to the way selective serotonin reuptake inhibitors (SSRIs) work. “Hypericin used to be thought of as the active ingredient with regard to treating depression,” explains Dr. Weed. “Currently it is thought that hyperforin is the active ingredient through effects on neurotransmitters in the brain similar to the effects of prescription antidepressants.”
When it comes to treating menopausal symptoms, the herbal supplement has been demonstrated to be effective at treating psychological symptoms related to menopause, such as sadness, anxiety, and stress, as well as physical symptoms such as hot flashes and night sweats. While the findings are statistically significant when St. john's wort extract is taken alone, when taken alongside black cohosh, a flowering herb, the research is even more compelling.
St. John’s wort’s ability to treat psychological menopausal symptoms is thought to act similarly to its ability to treat mild depression and seasonal affective disorder, while its effects on physical symptoms such as hot flashes are less widely studied and understood. Because of the way St. John’s wort affects the brain’s serotonin levels, it may also be effective in treating premenstrual syndrome.
While this application of St. John’s wort is not as widely studied as others, the supplement has been shown to act as an anti-inflammatory agent in mice and rats by limiting the expression of inflammatory agents in the body.
A concert of extracts from St. John’s wort extract work together to decrease the activity of or decrease the production of certain inflammatory agents.
4.Minor cuts and burns
According to Dr. Nance, the herbal supplement is also sometimes used as an antibacterial treatment for minor cuts and burns. While there are plenty of topical St. John’s wort products on the market, studies indicate that oral formulations have a more positive impact on wound healing than topical treatments containing St. John’s wort.
St. john's wort extract is believed to be successful in treating small wounds due to hyperforin, the main antibacterial component in the herbal supplement. Hyperforin acts to slow the growth of certain types of microorganisms that are present within cuts and wounds. Further studies indicate that the hypericin in St. John’s wort could be effective in inactivating certain types of viruses.
