Sharp-Nosed Pit Viper

Traditional Use

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.

Secondary Actions

• Bai Hua She is usually processed, powdered, or prepared with wine rather than simmered casually in long decoctions; the goal is to preserve its channel-penetrating action while controlling toxicity.
• This record follows the classical Bai Hua She lineage centered on Qi She and the sharp-nosed pit viper; the separate 'Jin Qian Bai Hua She' stub remains available for the juvenile krait trade concept imported elsewhere in the spreadsheet.

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 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.
