The FDA reviewed Halfhill Farm's website, www.halfhillfarm.com, in August 2020 and determined that products including Reuma-Art X-Strength, Turkey Tail Mushroom Dual Extract, Cordyceps Mushroom Dual Extract, Lion’s Mane Mushroom Dual Extract, Chaga Mushroom Dual Extract, Red Reishi Mushroom Dual Extract, and Propolis Extract are marketed with claims establishing them as drugs under section 201(g)(1)(B) of the FD&C Act [21 U.S.C. § 321(g)(1)(B)]. These claims, such as "anti-inflammatory" properties for Reuma-Art X-Strength ingredients and scientific citations for Turkey Tail Mushroom Dual Extract, indicate intended use for disease cure, mitigation, treatment, or prevention.
