Turkey Tail Double Extract Tincture made with 100% Wild Foraged Alaskan Turkey Tail. Our Turkey Tail tincture is a potent healer for many organs including liver, gut and blood. Turkey tail is supportive as an immune system toner and in lowering insulin resistance. Turkey tail is also known for its anti-cancer properties. Due to the unique and durable texture of turkey tail mushroom we prefer tincture form. Double extract is both an organic grain alcohol and hot water extract, in a vaccuum for maximum bioavailability.
