Make room for the mushrooms...

Here at Therapy Organics, we LOVE medicinal mushrooms. Our Nutritional Therapist, Jackie, has a particular passion for them following her Mycology training at the Hifas da Terra headquarters in Galicia. An amazing place blending the power of nature with the latest science and research, their labs nestled in amongst the forest where the organic chestnut trees are adorned in the growing mushrooms. Medicinal mushrooms have been used for centuries for their healing properties... now finally science is catching up and providing evidence of their health giving qualities.
