Cornus officinalis
Also known as Shan Zhu Yu
Pronounced shahn joo yoo; Cornelian Cherry: kor-NEE-lee-un; Cornus officinalis: KOR-nus oh-fiss-ih-NAH-liss
Warm, sour, astringent tonic: the great securer that gathers scattering essence, qi, blood, and sweat back to the Kidney and Liver, holding a deficient, leaking terrain together without excessive drying.
NEEDS REVIEW: Not covered by the AHPA Botanical Safety Handbook and lacking formal safety studies. Traditionally used only within practitioner-prescribed Kidney-tonifying formulas, some of which are given for threatened miscarriage from Kidney deficiency, and it is not a documented abortifacient; but consumer sources conflict (some vendors flag avoidance). Given the absence of formal data, avoid self-prescription in pregnancy and use only under a qualified practitioner. (No AHPA/NCCIH monograph; vendor safety labels; Bensky et al. 2004.)
NEEDS REVIEW: No specific lactation data located and no traditional contraindication reported; not covered by AHPA or NCCIH. Given the absence of formal data, restrict to practitioner-guided use during breastfeeding. (No AHPA/NCCIH monograph.)
Traditionally used at reduced pediatric doses within TCM formulas for childhood enuresis and night sweats under practitioner supervision. The pitted fruit flesh is a low-toxicity, food-like fruit. Reserve concentrated extracts and any collapse-dose amounts for practitioner oversight.
Use the pitted flesh (Shan Yu Rou) only; the seed is not used. High collapse-rescue doses (30-60 g) are practitioner- or hospital-administered, not for self-dosing. Its sour-astringent, warming nature can lock in an unresolved infection or aggravate damp-heat, so it is held until any active exterior or damp-heat pathogen is cleared.
Damp-heat of the lower jiao, painful or difficult urination from heat, blazing ministerial fire with priapism or frequent erections, and unresolved exterior or excess (acute infectious) conditions. Not for self-treatment of shock or collapse, which is a medical emergency.
Commercially orchard-cultivated at scale in China (notably Henan and Zhejiang) and not listed as at-risk; not a United Plant Savers species (that registry covers North American natives). Prefer cultivated, pit-removed flesh from reputable suppliers and confirm it is sulfite-free and correctly identified as Cornus officinalis rather than adulterant Cornaceae fruit.
Not named in the canonical biblical texts. An East Asian materia medica herb, first recorded in the Chinese classic Shennong Ben Cao Jing (c. 200 CE) as Shan Zhu Yu; native to China, Korea, and Japan.
