A schematic diagram of the common mechanisms by which natural products reduce chemotherapy and radiotherapy-induced side effects. Natural products including crude extracts, bioactive components-enriched fractions, and pure compounds derived from herbs as well as herbal formulas can effectively reduce chemotherapy and radiotherapy-induced side effects mainly due to their anti-oxidative and anti-inflammatory activities. Moreover, some natural products can attenuate chemotherapy and radiotherapy-induced oral mucositis by anti-infection, mitigate gastrointestinal toxicity by regulating gut microbiota, hepatotoxicity by protecting mitochondria, nephrotoxicity by modulating immunity, hematopoietic system injury by improving hematopoietic microenvironment, cardiotoxicity by balancing energy metabolism, and neurotoxicity by protecting nervous system.
