Dried node of the lotus rhizome (Nelumbo nucifera, Nelumbonaceae) — the joint of the underwater rhizome from the same plant yielding Lian Zi, He Ye, Lian Xu, and Lian Fang. Enters the Liver, Lung, and Stomach channels. Sweet, astringent, and neutral; constrains and stanches bleeding while also transforming stasis, valued for hemostasis without retaining pathogenic stasis.
Reference range for non-pregnant adults. Not a personalized prescription. Pregnancy, lactation, and pediatric use require specialist supervision.
Protective guidance only — when to avoid or use with caution. This block deliberately omits pregnancy, lactation, and pediatric dosing: any such use must be managed by a qualified TCM practitioner or appropriate specialist.
