These are found as independent elements of medical encyclopedias, as, e.g., in “The Canon of Medicine” by Ibn Sina (Books Two and Five) or as independent works on simple drugs (Materia Medica) and pharmacopeias. Works on simple drugs (adwiyat al-mufrada) include a description, properties and uses of simple drugs of mineral, plant and animal origin. Usually the information is arranged in abjad order of the Arabic alphabet letters. The collection of the al-Biruni Institute of Oriental Studies of the Academy of Sciences of the Republic of Uzbekistan keeps works by the above-mentioned authors, Ibn Jazla (Inventory No. 3761), Najib al-din Samarqandi and Yusufi (19 copies).
You can learn more about this topic in the book-album “The Collection of the Al-Biruni Institute of Oriental studies, the Academy of Sciences of the Republic of Uzbekistan” (part two, “Miniature and Calligraphy”) (Volume XXII) from the series "Cultural Legacy of Uzbekistan in the World Collections".
The main sponsor of the project is the oilfield services company Eriell-Group.
