Of the multiple herbal extracts with evidence to support the immune system, echinacea purpurea is possibly the best-known and most widely-used. Numerous research trials show that it can significantly reduce the recurrence of the common cold and reduce the duration of symptoms in an active infection.
Andrographis paniculata and panax quinquefolius have also demonstrated similar results with respect to the common cold due to their andrographolide and polysaccharide content, respectively. Interestingly, astragalus membranaceus has been found to upregulate the expression of CD4 and CD8 T cells, various cytokines, and macrophages even more effectively than echinacea purpurea.
Ganoderma lucidum, commonly known as reishi, is an effective immunomodulator with beneficial effects on natural killer cells and lymphocytes in individuals that are ill or exposed to highly stressful circumstances. Supplementation with reishi has also been shown to improve well-being, mood and energy in cancer patients and improve wellbeing in those with weakness and fatigue.
Equally important are the vitamins and minerals needed for healthy regulation of the immune system. Zinc is required for the normal development and function of natural killer cells, neutrophils, macrophages and various cytokines. Research has shown that it is capable of preventing viral replication in the upper respiratory tract, making it acutely indicated during the common cold and other infections. Much like zinc, vitamin C is commonly used today as a stand-alone treatment to reduce the severity and duration of the common cold.
Collectively, the carefully selected blend of standardized herbal extracts, a mushroom extract and immune-regulating nutrients in Immune Matrix make it a highly effective formula against infections of the upper respiratory tract such as the common cold. Immune Matrix is also effective for supporting the immune system in those with poor immunity or when used preventatively during times of stress.
