Many fungal and plant derived bio active polysaccharides with a broad range of immunomodulatory activities are found in TCM. Some
such polysaccharides have been developed into drugs and showed clinical efficacy in controlled trials while the majority of such compounds remain as nutraceuticals with only preliminary research. Such polysaccharides are generally non-toxic and also possess other bio activities such as inducing differentiation, stimulating hematopoiesis, anti-metastasis, and antiangiogenesis, which make them ideal adjuvants in modern cancer therapy.
