Rating (out of 5): 2

Trametes species, most notably Trametes versicolor (also known as Turkey Tail), have a long history of use in traditional medicine systems, especially in East Asia. These mushrooms have been used to support immune function and as adjunct therapies for various illnesses, including respiratory infections like colds. Historically, preparations made from Trametes are believed to bolster the body’s resilience to infections, and some traditional herbalists recommend their use during cold and flu season.

Scientific investigations have identified polysaccharide compounds such as PSK (polysaccharide K) and PSP (polysaccharide peptide) in Trametes versicolor, which demonstrate immunomodulatory effects in vitro and in animal studies. Some research suggests these compounds enhance immune cell activity, potentially increasing the body’s ability to combat viral infections. However, robust clinical studies specifically assessing the efficacy of Trametes for treating or preventing the common cold in humans are lacking. Most clinical research focuses on its use as an adjunct therapy in cancer, not on antiviral effects against cold viruses.

In summary, while the traditional use of Trametes mushrooms for immune support and colds is well-established, scientific evidence supporting their direct antiviral effect against cold viruses in humans is limited and indirect. The overall evidence level for this specific use is therefore moderate and primarily based on tradition rather than rigorous clinical validation.
