A liquid extract of six mushrooms harvested in the mycelial stage of growth, the stage in which the active constituents are most concentrated. The mushrooms contained in Mycocyclin are Ganoderma lucidum (Reishi), Lentinula edodes (Shiitake), Cordyceps sinensis (Cordyceps), Grifola frondosa (Maitake), Coriolus versicolor (Turkey tail), and Tremella fruciformis (Snow fungus), all of which have been used in Chinese medicine for centuries to support the immune system. All contain bioflavonoids, essential fatty acids, minerals, vitamins and other beneficial nutrients and each has its own individual action on the immune system. Collectively they contain the active constituent beta-1, 3-glucan, which has been shown to increase the white blood cell count. Mycocyclin has a somewhat stimulating effect on the immune system.
