Mitochondria is one of the most important organelles in eukaryotic cells,which is also the only organelle containing genetic material other than the nucleus.In the process of aerobic respiration,mitochondria produces more or less reactive oxygen species,however,excessive accumulation of reactive oxygen species will lead to mitochondrial dysfunction and participation of occurance and acceleration of numbers of diseases.With China's support and exploration of traditional Chinese medicine,many studies show that the mechanism of a large number of Chinese medicines is related to mitochondria.Therefore,this paper focuses on research progress of Chinese medicine on mitochondria under oxidative stress in cardiovascular diseases.
