Phyllostachys nigra (Lodd.) Munro var. henonis (Mitf.) Stapf ex Rendle; Bambusa tuldoides Munro (Bambusae Succus)
Nature and flavour. Sweet and cold; Heart, Lung and Stomach systems.
Traditionally classed as clearing heat and sweeping phlegm, settling fright and opening the orifices. The drug is not a plant part but a liquid: the sap that runs from the culm of certain bamboos when the green stem is heated, collected and used as a juice, usually fresh or as a dried soluble preparation. Recorded for hot, thick phlegm with cough and congested breathing, for phlegm-heat misting the orifices with clouded consciousness, and for fright and convulsions in febrile illness attributed to phlegm-heat. It is grouped with the phlegm-resolving drugs and is the cold counterpart to the warm phlegm-transforming drugs on this page.
性味归经。甘，寒；归心、肺、胃经。
传统归类为清热豁痰、定惊开窍。本品并非植物器官，而是竹类鲜茎加热后沥出的汁液，收集后作液体制剂使用，多为鲜用或制成干膏。古籍用于痰热咳喘、痰稠难咯，痰热蒙蔽清窍之神昏，以及热病痰热所致惊风、抽搐。本品归在化痰药中，是本页温化寒痰药的寒凉对应者。
由加热竹茎收集的液汁并非标准化制剂，市售品的浓度与制法差异很大。古籍所载主治包含神昏与抽搐，二者均属须立即就医评估的急症，本品对任何一种的结局均无确立证据。性寒，脾胃虚寒者传统上忌用；古籍亦不用于痰液清稀或属寒之证。注意勿与竹茹混淆 —— 同出一物而入药部位不同，传统用途亦不同；亦不同于天竺黄。孕期与哺乳期安全性未确立。
