Organic Reishi TinctureWhat makes Bristol Fungarium's Reishi tincture unique? UK Native Strain Our Reishi was cloned from a species we found locally to our farm in Somerset, UK. As much as possible we utilise native strains, not only to help us get closer once again to the land where so much of the knowledge has been lost but most importantly to have as little effect as possible on local biodiversity and tread as lightly as possible on the earth.
