This Osha root is ethically wildcrafted and superb quality. We tincture it at a 1:5 ratio in organic cane alcohol and reverse osmosis maple tree water. According to Dr. Sharon Marie Tilgner: Osha is Antiviral, Carminative, Diaphoretic, Diuretic, and Immune Stimulating. We find this highly aromatic plant to be ideal for respiratory congestion and digestive disturbance.
