Black-Tail Snake — Classic Formulas
Wu Shao She · Zaocys
Primary Actions
- Dispels Wind-Damp and unblocks the collaterals - used for stubborn wind-damp arthralgia, numbness, spasms, and chronic weakness of the limbs when the channels need a penetrating animal medicinal.
- Extinguishes wind and stops convulsions - applied for childhood convulsions, tetanus, tremor, and post-stroke spasticity when internal wind lodges in the channels.
- Searches out wind to relieve itching - valued for rubella, pruritic skin disorders, and chronic itchy dermatoses that resist gentler wind-relieving herbs.
- Offers a milder snake-medicine option than toxic viper drugs - Wu Shao She is traditionally chosen when the practitioner wants the collateral-unblocking action of snake medicines without the stronger toxicity of Bai Hua She.
Classic Formulas
- Da Huoluo Dan (大活络丹) - major wind-damp and stroke-sequelae formula in which Wu Shao She joins other animal and plant medicinals to dredge collaterals, alleviate pain, and calm internal wind.
- Classical snake-pair prescriptions combining Wu Shao She with Bai Hua She or Wu Gong - used when deeper channel wind, spasms, or resistant skin disease require stronger search-out action than plant medicinals alone.
