Active Ingredient TCVM Actions
Rehmannia 6 is built on a classic three-tonic, three-draining structure. Each herb contributes targeted actions that work together to nourish Kidney Yin while preventing Stagnation:

- Shan Zhu Yu (Cornus) - Asiatic Cornelian Cherry: Tonifies Liver and Kidney Yin and Yang; stabilizes and binds to prevent leakage of Essence and supports reproductive health.
- Shan Yao (Dioscorea) - Chinese Yam: Tonifies Spleen, Lung, and Kidney Qi; stabilizes Jing and supports digestive and metabolic function alongside the tonic herbs.
- Ze Xie (Alisma) - Water Plantain Rhizome: Drains Damp and clears Heat through gentle diuresis; prevents Shu Di Huang from becoming too cloying and supports kidney and bladder function.
- Fu Ling (Poria) - Poria Mushroom: Drains Damp and strengthens the Spleen; counterbalances Shan Yao and supports fluid metabolism and Shen calm.
- Mu Dan Pi (Moutan) - Tree Peony Root Bark: Clears Heat and cools Blood; clears deficiency Heat arising from Yin deficiency and counterbalances the warming nature of Shan Zhu Yu.
