Clinical commentary 臨床

**This must not be prepared.** Both aconites raw, together with realgar, which is arsenic sulphide. The second name — Snatch Back Life Pill — is honest about the circumstances: a patient in opisthotonos was going to die, and a prescription of this kind was a last throw. The inclusion of gastrodia and angelica dahurica alongside the poisons is the only part that follows the section's own logic. Recorded here as history. — Eui Young (Justin) Chung, L.Ac., Dipl. O.M.
