St. John's Wort Gold
St. John's wort is a medicinal herb with a long history of use in Europe as an herbal remedy to support mental health and emotional wellness. The aerial parts of the herb that are used medicinally are harvested during the flowering season and then dried to make the extract. St. John's wort contains many beneficial compounds, including hypericin and hyperforin, which are believed to be the source of its medicinal potency. The most important quality concern with St. John's wort is the residual amount of cadmium in the extract. The herb is a known cadmium collector and has a tendency to absorb large amounts of cadmium from the soil. To ensure a pure extract, it is extremely important that St. John's wort is grown in soil that is free of this heavy metal, and care is taken during extraction to ensure removal of any residual trace amounts.
