The dried root bark of Lycium chinense or L. barbarum (Solanaceae). Cold and sweet, entering the Lung, Liver, and Kidney channels. Excels at clearing vacuity heat and abating bone-steaming; also clears Lung fire. From the same plant as Gou Qi Zi (the berry) but with entirely different functions.
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.
（枸杞）味苦，寒。主五内邪气，热中消渴，周痹。久服坚筋骨，轻身不老。
