Cordyceps • Stimulate ATP production (Yang) • Enhance immune response (Yin)
Yang vs. Yin • Yang but not Yin herbs stimulate ATP production • Pharmacological basis of Yang-invigoration in Chinese medicine Trends in Pharmacological Sciences (2004)
Yang-Invigorating Herbs Yang - oxidation Yin - antioxidation Why Yang herbs contain high antioxidant activity?
