The dried ripe fruit of Gardenia jasminoides (Rubiaceae). Enters the Heart, Lung, and Triple Burner channels. Bitter and cold, it is the key herb for draining fire from all three burners and eliminating vexation. Used raw it courses the qi level and drains fire; when scorched it enters the blood level and stops bleeding. Featured in Zhi Zi Chi Tang for heat-induced vexation and restlessness.

栀子主含栀子苷、藏红花素（crocin）等环烯醚萜及类胡萝卜素成分，具有保肝利胆、解热、抗炎、镇静及降压作用，为清热泻火除烦的药理依据。
Gardenia fruit contains iridoid glycosides (geniposide) and carotenoids (crocin, crocetin) with hepatoprotective, choleretic, antipyretic, anti-inflammatory, sedative and hypotensive effects, providing the basis for its heat-clearing, fire-draining and restlessness-resolving actions.
《中国药典》以栀子苷为含量测定指标。
The Chinese Pharmacopoeia uses geniposide as the assay marker.
Chen & Chen 引述栀子苷在动物模型中显著降低 ALT 并改善胆汁淤积。
Chen & Chen cite geniposide markedly lowering ALT and improving cholestasis in animal models.
