Traditional Uses of Shu Di Huang in Chinese Medicine
In Traditional Chinese Medicine, Shu Di Huang is classified as a Blood and Yin Tonifying Herb. Traditionally, it is used to:
• Nourish blood
• Tonify yin
• Support Liver and Kidney systems
• Replenish essence (jing)
• Support balance in deficiency patterns
In classical herbal theory, Shu Di Huang enters the Liver and Kidney channels, where it helps restore balance when blood deficiency, yin deficiency, or depletion disrupt normal physiological function.
Because of these properties, Shu Di Huang is a foundational herb in many classical formulas.
