The ‘Yin–Yang' theory is an ancient Chinese philosophy that underlies the practice of traditional Chinese medicine. Although Yang-tonic herbs tend to boost body function possibly through enhancing the mitochondrial oxidative processes, the Yin property (i.e. antioxidant potential) of these herbs can also play a role in safeguarding mitochondrial ATP generation. The pharmacological basis of ‘Yang-invigoration' by Chinese tonic herbs might be due primarily to the enhancement of mitochondrial ATP generation.
