The dried ripe seed kernel of Pinus koraiensis (Pinaceae). Enters the Lung, Liver, and Large Intestine channels. Sweet and warm with a rich, oily quality, Song Zi Ren moistens the lungs and stops cough, lubricates the intestines to free the stool, and nourishes fluids to extinguish internal wind. Commonly used for dry cough in elderly or post-febrile patients and for constipation due to fluid insufficiency.
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.
