Sharp-Nosed Pit Viper — Classic Formulas

Bai Hua She · Deinagkistrodon acutus

Primary Actions

  • Dispels Wind-Damp and unblocks the collaterals - used for stubborn Bi syndrome, numbness, joint pain, and chronic channel obstruction that ordinary wind-damp herbs do not reach deeply enough.
  • Extinguishes wind and stops spasms - applied to tetany, convulsions, tremor, facial paralysis, and post-stroke hemiplegia when internal wind has lodged in the channels and sinews.
  • Searches out wind to relieve itching and chronic toxic skin disease - classically used for persistent pruritic eruptions, scaly skin disorders, and wind-toxin conditions with numbness or deformity.
  • Acts as the stronger, more toxic counterpart to Wu Shao She - traditionally chosen when a penetrating snake medicinal is needed for severe, long-standing obstruction rather than milder patterns.

Classic Formulas

  • Da Huo Luo Dan (大活络丹) - major wind-damp and stroke-sequelae formula in which Bai Hua She helps search out deep channel wind, relieve pain, and restore movement.
  • Classical Bai Hua She powders and medicated-wine preparations - the processed snake is used alone or with other wind-extinguishing substances when chronic Bi, paralysis, or spasms have become fixed and stubborn.
  • Bai Hua She with Wu Shao She or Quan Xie - traditional pairings used when severe wind-damp numbness, convulsions, or difficult skin disorders require stronger animal medicinals than plant herbs alone.

Classical Text References

  • Me & Qi describes Bai Hua She as sweet, salty, warm, entering the Liver channel, and specifically stronger and more toxic than Wu Shao She for stubborn Wind-Damp, spasms, itching, and windstroke sequelae.
  • Sacred Lotus preserves the older cross-referencing of Bai Hua She with Agkistrodon and Bungarus naming traditions, showing why the modern trade and older texts can look taxonomically inconsistent.
  • DATA QUALITY NOTE: the source XLSX imported this file with the Latin 'Bungarus Parvus' while also creating a later stub for Jin Qian Bai Hua She under the same Latin. Modern primary references identify the mainstream Bai Hua She drug more closely with Qi She / Deinagkistrodon acutus, so this record corrects the herb identity while leaving the duplicate krait-style record for separate cleanup.
