Bamboo Juice (Bamboo Sap) Classic Formulas

Primary Actions

Clears Heat and powerfully resolves phlegm - used for thick, sticky yellow sputum, chest oppression, wheezing, and severe phlegm-heat cough when milder bamboo medicinals such as Zhu Ru are not strong enough.
Opens the orifices in phlegm-heat obstruction - classically selected for sudden unconsciousness, aphasia, locked jaw, or collapse patterns in which hot phlegm mists the Heart and blocks clear sensory function.
Settles fright and stops convulsions - employed in pediatric febrile convulsions, epilepsy, or internal wind presentations where Heat and phlegm combine to agitate the spirit and channels.
Penetrates the channels and collaterals - used for post-stroke paralysis, limb spasms, and stubborn phlegm lodged beyond the chest because its slippery sap is understood to travel where ordinary phlegm herbs do not.

Ding Xian Wan (定痫丸) - a classical antiepileptic formula in which Zhu Li may be taken with ginger juice to address phlegm-heat, convulsions, and obstruction of the orifices.
Qing Gong Tang (清宫汤) - warm-disease formula traditions add Zhu Li and pear juice when heat-phlegm clouds the Pericardium with agitation, delirium, or blocked consciousness.
Qing Fei Tang (清肺汤) - respiratory heat-phlegm formula traditions use Zhu Li to dissolve stubborn phlegm, open the chest, and help descend constrained Lung Qi.

Ming Yi Bie Lu records Zhu Li as sweet, greatly cold, and non-toxic, indicating it for sudden wind-stroke, vexation, great Heat in the chest, and disorders of phlegm obstruction.
Ben Cao Yan Yi praised Zhu Li as a substance able to treat phlegm lodged anywhere in the body, including the chest, limbs, organs, channels, and membranes, which underlies its channel-penetrating reputation.
Danxi lineage teaching emphasized that Zhu Li should be taken with ginger juice because without ginger it does not effectively travel through the channels to reach lodged phlegm.
