Clinical commentary 臨床

The most elaborate preparation in the chapter and one of the tradition's famous medicines. Gold and two minerals are boiled first, the botanicals added after, and mirabilite stirred in with a willow branch until it crystallizes — the crystals are what give the name. 狂易呌走 — mania with shouting and running about — is the presentation, and it is delirium in severe fever. 野道熱毒, heat toxin of the wayside, means heat stroke in a traveller. Modern Ziхue San is still made and still used in hospitals in East Asia for high fever with convulsion, though without the gold, rhinoceros horn or cinnabar. **Contains rhinoceros horn, antelope horn and musk, all CITES Appendix I and prohibited in trade; and cinnabar, which is mercury sulfide. This cannot be prepared or taken. High fever with delirium or convulsion is a medical emergency.** — Eui Young (Justin) Chung, L.Ac., Dipl. O.M.
