Premium Quality Medicinal
Coriolus Versicolor Mushrooms and Mushroom Extracts

Known as PSK in Japan and PSP in China, the immune supporting beta glucans extracted from the medicinal mushroom Coriolus versicolor are one of the first herbs from Traditional Chinese Medicine to be fully backed by modern scientific research. *

Using science to enhance the knowledge and benefit these ancient herbal traditions have to offer is the focus of what we do at JHS Natural Products.

Our Coriolus extract is a full spectrum extract formulated with two goals in mind:

  • Delivering the complete essence of what made these mushrooms valuable in traditional herbalism.
  • Delivering guaranteed levels of all the primary active compounds identified and studied in the supporting scientific research.

From the selection of the genetics to the cultivation techniques, from the temperature of the final extraction to the most informative label on the market, we control each and every step. Every Mushroom Science extract is carefully crafted to deliver the maximum benefit each medicinal mushroom has to offer.
