Anti-aging role of Chinese herbel medicine: an overview of scientific evidence from 2008 to 2018

The aging of the population has become a global health problem. It is an important risk factor for major diseases such as cardiovascular disease, Alzheimer's disease, Parkinson's disease, and cancer. Presently, there is no definite and effective anti-aging treatment. Chinese herbal medicine has a long history of application and is often used for aging-related diseases in China. A large number of clinical and preclinical studies on the anti-aging effect of Chinese herbal medicine has been performed. Through literature research, we reviewed the anti-aging clinical research of Chinese herbal medicine and preclinical research of Chinese herbal medicine monomers, components, extracts, and compounds, and their mechanisms. Results from preclinical studies have shown that Chinese herbal medicines have beneficial anti-aging effects. The mechanism mainly includes anti-oxidative stress, anti-inflammatory, neuroprotection, apoptosis and mitochondrial function regulation, etc. However, more detailed high-quality clinical trials are required for future investigation of the anti-aging effects of Chinese herbal medicines.
