The work
Zakhireh-ye Khwārazmshāhī — Treasure of the Khwarazmshah
ذخیرهٔ خوارزمشاهی
1042–1137 CE
The first major medical encyclopedia written in Persian rather than Arabic — the book that brought Avicenna's tradition into Persian homes.
Jurjani served the Khwarazmshah dynasty and wrote his ten-book Zakhireh in Persian so that physicians and educated readers of Khorasan could study medicine in their own language. Until then, the great medical literature circulated in Arabic; Jurjani made the tradition domestic.
The Zakhireh follows the structure of the Canon but with a distinctively Persian voice — closer to daily practice, richer in local herbs and foods, and organized to be usable by a working physician rather than only by scholars.
We cite Jurjani when a Persian remedy or a Persian name for an herb has an earlier written record in the Zakhireh than in the Arabic Qanun, and to preserve the specifically Persian (rather than pan-Islamic) line of the tradition.
What this text is known for
- First comprehensive medical encyclopedia in Persian prose.
- Preserved Persian-language herbal names, dosages, and regional remedies.
- Bridged Avicennan theory with Khorasani everyday practice.
Jurjani anchors guides where we want the specifically Persian (not pan-Islamic) tradition of a food or herb — regional pairings, home preparations, and Persian herbal vocabulary.
Traditional Persian sources describe how a herb, food, or ritual was understood — never on their own a claim about modern outcomes. Where modern trials agree or disagree, the Living Library labels the difference clearly.
