Effects and Efficacy of Lycii Cortex

Hello, Lycii Cortex (the root bark of *Lycium chinense* or *Lycium barbarum*) is a traditional Chinese medicinal herb with cold and dry properties. It enters the Lung, Liver, and Kidney meridians and functions to cool the blood, eliminate deficient-heat (i.e., “steaming” heat), clear Lung heat, and subdue fire. Clinically, it is commonly used to treat conditions such as tidal fever, night sweats, and internal heat-induced thirst and polydipsia—symptoms often arising from Yin deficiency. However, please note that Lycii Cortex is not suitable for everyone; individuals with a constitutionally cold or deficient-cold pattern should generally avoid its use. I hope this information is helpful. Wishing you good health!
