Anti-Aging Natural Products
Aging is an unavoidable process, leading to cell senescence due to physiochemical changes in an organism. The purpose of anti-aging activities is to increase the life span and the quality of life. Anti-aging activities are primarily involved in the therapies of age-related disorders such as Parkinson's Disease (PD), Alzheimer's Disease (AD), cardiovascular diseases, cancer, and chronic obstructive pulmonary diseases. Natural products are known as effective molecules to delay the aging process through influencing metabolic pathways and thus ensure an extended lifespan.
