Hempleaf Negundo Chastetree Leaf

Traditional Use

Primary Actions

• Releases the exterior and transforms dampness - Mu Jing Ye is used for wind-cold or damp-type early illness with headache, heaviness, body discomfort, and lingering exterior obstruction.
• Transforms phlegm and calms wheezing - traditional indications include cough, abundant phlegm, and asthma-like breathing difficulty.
• Regulates the middle and relieves pain - older use extends to abdominal pain, damp summer disorders, and dysenteric or gastroenteritic patterns.
• Resolves toxicity and relieves itching - external use includes rashes, foot fungal conditions, swollen breasts, and bites or minor toxic swellings.

Secondary Actions

• This leaf record should stay distinct from the far better-known fruit medicines in the Vitex group; the plant part materially changes the traditional profile.
• Mu Jing Ye sits closer to an aromatic leaf medicine with respiratory and dampness applications than to a simple flavor variant of Mu Jing Zi.

Classic Formulas

• Leaf-decoction exterior and cough treatments - traditional use for wind-cold with phlegm or wheezing.
• Mu Jing Ye washes and poultices - local-use strategy for itching, damp skin problems, and toxic swelling.
• Respiratory combinations with qi-descending or phlegm-transforming herbs - the practical pattern when cough and wheeze dominate.

Classical References

• The official Chinese reference platform describes Mu Jing Ye as pungent, bitter, and neutral, with actions of releasing the exterior, transforming dampness, relieving wheezing, and resolving toxicity.
• Broader Chinese materia medica summaries place the leaf in a Lung-Liver-Stomach style pattern space, reflecting its use for respiratory, damp, and pain presentations.
