Tamarisk Tops … Classic Formulas
Cheng Liu · Cacumen Tamaricis
Primary Actions
- Dispels wind and gently induces diaphoresis ... Cheng Liu is used for early exterior presentations when a mild venting herb is preferred.
- Promotes eruption of measles and rash ... tamarisk tops are classically used when eruptions do not vent smoothly to the surface.
- Removes toxicity and relieves itching ... external or internal use is described for pruritic eruptions, superficial toxic lesions, and damp-wind irritation.
Classic Formulas
- Cheng Liu with Bo He, Niu Bang Zi, or Chan Tui ... classic eruption-guiding logic for measles or trapped wind-heat rash.
- Decoction-wash use for itching and superficial toxic lesions ... a practical route emphasized in later external-use notes.
- Mild exterior-release pairings for wind-cold with rash tendency ... older usage where sweating and eruption-promoting overlap.
Classical Text References
- Traditional summaries describe Cheng Liu or Xi He Liu as sweet, pungent, and neutral, entering the Lung, Stomach, and Heart to vent the exterior and bring rash outward.
- Its identity is more about opening the surface and helping expression than about strong direct heat-clearing.
