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).

Immune enhancement and 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 properties
H. perforatum extract exhibited a wound-healing activity whose mechanism of action is similar to that of Centella asiatica (TECA).
