St. John's Wort

Hypericum perforatum

St. John's wort (SJW)(Hypericum perforatum) is a medicinal herb which contains hypericin, the major neuroactive component of the plant. It
has been used as a herbal remedy for a number of conditions since the ancient Greeks. H. perforatum is a freely branched, flowering herb which produces 5-petaled yellow flowers which thrives in poor soils, and is commonly found in meadows, fields, waste areas, roadsides, and abandoned mines and quarries. LI-160 refers to a standardized extract of hypericum perforatum which contains precisely 0.3% hypericin (250µg per 300mg).

Antiviral: H. perforatum extract (HPE) has demonstrated significant therapeutic efficacy and improvement of immunologic functions for chickens infected experimentally with infectious bursal disease virus.

Wound healing: H. perforatum extract exhibited a wound-healing activity whose mechanism of action is similar to that of Centella asiatica (TECA).
