Turkey Tail, also sometimes referred to as Coriolus, is an adaptogen, a unique class of herbs that help support the body's ability to deal with physical and emotional stress. Turkey is a rich source of the polysaccharides known as Beta Glucans; studies have shown that Turkey Tail may provide deep immune system support by promoting healthy levels of T-helper immune cells. Turkey Tail contains two specific Beta Glucans, known as PSP and PSK, that has been the subject of extensive immune support human clinical research. In 2011 the National Institute of Health (NIH) completed a 7-year study on the immune health benefits of Turkey Tail given to women with breast cancer; the research showed that Turkey Tail supported healthy immune function with no side effects. Studies suggest that Turkey Tail may also support healthy lung function and respiratory wellness.
