Ibn Sina’s Canon of Medicine organised medical learning into five books and became influential in Arabic and Latin medical traditions. Its discussion of testing drugs belongs to Book Two. The conditions he proposed should be read within medieval medicine, rather than called modern controlled clinical trials. The physician and philosopher wrote while moving among courts and serving rulers in several capacities. His life is partly recoverable through the autobiographical account continued by his pupil al-Juzjani.
“Medicine is a science by which we learn about the conditions of the human body in health and in the absence of health.”
c. 970–980 to 1037 CE
Born in Afshana, near Bukhara (in present-day Uzbekistan), at an uncertain date, conventionally given as around 980 but placed earlier by some scholars. Died in Hamadan, western Persia, in June 1037 CE. He lived through the collapse of the Samanid dynasty, the rise of the Ghaznavids, and the fragmentation of the Persian plateau into rival principalities — and somehow, through all of it, kept writing.
Hundreds
The Canon of Medicine catalogued hundreds of medicinal substances, describing their properties, preparation, and application. Each entry documented the drug's degree of heat, cold, moisture, and dryness — following Galenic humoral theory — alongside empirical observations of its effects. The drug index alone made the Canon a standard pharmaceutical reference for centuries.
5
The <em>Qānūn fī al-Ṭibb</em> was organised into five books: general principles of medicine; simple drugs; diseases organised by organ system from head to toe; conditions affecting the whole body; and compound medications. This systematic structure — from theory to practice to pharmacology — became the template for how medicine was taught and organised in both the Islamic world and medieval Europe.
Several
Translated into Latin in the twelfth century, the Canon became an important text in European medical teaching into the seventeenth century. Its influence varied across institutions and periods; the long history includes abridgments, commentaries and challenges to its authority.

Defining Events
The Canon of Medicine
The Qānūn fī al-Ṭibb brought a large medical tradition into a carefully organized synthesis. Where al-Razi had compiled empirical observations in the encyclopedic but unsystematic Hawi, Ibn Sina created a logical architecture: a framework in which every disease, every drug, every treatment had its place. Book One laid out the principles of medicine — the elements, the humours, the temperaments, the anatomy of organs. Books Two through Five moved systematically from simple drugs to compound remedies, from diseases of the head to diseases of the body as a whole. The Canon did not merely compile — it organised, argued, and synthesised. When it reached Latin Europe in the twelfth century, it joined other medical syntheses in a developing teaching tradition. Its organization helped make it an influential reference.
The Prodigy of Bukhara
Ibn Sina presents his early education as a rapid advance through the sciences, while admitting a memorable difficulty with Aristotle’s Metaphysics. Al-Farabi’s account helped him understand the purpose of a text he says he had read forty times. His service treating Nuh ibn Mansur brought access to the royal library. These episodes come from an autobiography that also expresses his philosophical ideal of independent inquiry; they are not an independent examination of mastery of every science.
The Book of Healing
Alongside the Canon of Medicine, Ibn Sina composed the Kitāb al-Shifāʾ — the Book of Healing. Despite its title, it was not a medical work but a philosophical encyclopedia covering logic, the natural sciences, mathematics, and metaphysics. In scope it was the most ambitious work of systematic philosophy since Aristotle, and in some respects surpassed it: Ibn Sina's treatment of the soul, of emanation, and of the relationship between essence and existence would define Islamic philosophy for generations and reappear — transformed — in the Latin Scholasticism of Aquinas and Duns Scotus. The Shifa also contained, in its section on music, one of the most sophisticated discussions of musical theory in the medieval world. Composition extended across periods of court service and political disruption.
Timeline
Born near Bukhara
Abū ʿAlī al-Ḥusayn ibn ʿAbd Allāh ibn Sīnā is born in Afshana, a small village near Bukhara in the Samanid province of Transoxiana (present-day Uzbekistan). His father was an administrator for the Samanid court. Bukhara was then one of the great cities of the Islamic world — capital of the Samanid dynasty, a centre of Persian culture and learning. The young Ibn Sina grows up in an environment of books, scholars, and Persian literary culture.
Prodigy in Bukhara
By his own account, Ibn Sina had memorised the Quran and a great deal of Arabic poetry by the age of ten. His father brought teachers to the house — a grocer who taught arithmetic, a philosopher named al-Natili who introduced him to logic. Ibn Sina quickly outpaced both. He began studying medicine at sixteen, finding it 'not difficult' — distinguishing himself by treating patients while still a teenager. He studied Aristotle's Metaphysics forty times before understanding it, and credits al-Farabi's commentary with finally unlocking its meaning.
Treats the Samanid Emir
Nuh ibn Mansur, the Samanid emir of Bukhara, falls ill with a condition that defeats his court physicians. Ibn Sina is summoned to assist in his treatment. His reward is access to the royal library of Bukhara — a collection of exceptional depth that contains texts Ibn Sina will later say he never saw again anywhere. He reads through it systematically. Later accounts attach a library-fire accusation to this episode; it should not be treated as an established act by Ibn Sina.
Fall of the Samanids
Bukhara falls to the Qarakhanids in 999. Ibn Sina’s later autobiographical sequence places his father’s death after he was twenty-one; the events should not be compressed into a single immediate flight in 999. His subsequent career took him through several courts.
Flight from Mahmud of Ghazni
Ibn Sina moves through several courts and towns as political conditions change. His autobiographical account records travel and patronage; later tales of Mahmud pursuing him through distributed portraits are less secure. Medicine and writing continue through these unsettled years.
The Book of Healing
Settled for a period under the patronage of the Buyid ruler in Hamadan, Ibn Sina begins composing the Kitāb al-Shifāʾ — the Book of Healing — a philosophical encyclopedia covering logic, mathematics, natural science, and metaphysics. Al-Juzjani records evening teaching and rapid composition amid court obligations. The scale of the work does not establish a fixed nightly production or daily clinical schedule.
Completion of the Canon
The Qānūn fī al-Ṭibb — the Canon of Medicine — is completed. Its five books organize medical principles, simple drugs, organ-specific diseases, other conditions, and compound remedies. It includes conditions for examining the action of drugs within a medieval medical framework. Composition began earlier in Gorgan and continued as Ibn Sina moved between courts; not every revision has a secure date.
Imprisonment and Escape
Political conflict leads to imprisonment at Fardajan. After about four months he is released in the aftermath of Ala al-Dawla’s campaign. His later departure from Hamadan in Sufi disguise is a separate episode; he travels with his brother, al-Juzjani and two enslaved attendants to Isfahan.
Isfahan and Final Years
Under ʿAlā al-Dawla in Isfahan, Ibn Sina enters his most productive late period — refining the Canon, working on music theory and astronomical observations, writing shorter philosophical treatises including the Ishārāt wa al-Tanbīhāt (Remarks and Admonitions), a late work using a compressed, suggestive style. He accompanies the ruler on military campaigns across Persia. On one campaign to Hamadan, he falls severely ill — possibly with colic — and dies in June 1037, at an age dependent on his disputed birth date. He is buried in Hamadan, where a twentieth-century mausoleum commemorates him.
Key Figures
Al-Razi (Rhazes)
Muhammad ibn Zakariyyā al-Rāzī (c. 854–925 CE) was the greatest empirical physician of the generation before Ibn Sina. His vast Kitāb al-Ḥāwī — The Comprehensive Book — compiled clinical observations on an unmatched scale and first distinguished smallpox from measles. Ibn Sina drew on earlier medical writing, including al-Razi, without accepting all its judgments. The unfinished Hawi and the deliberately organized Canon have different forms and histories. The two figures together — al-Razi's empirical richness, Ibn Sina's systematic framework — gave medieval medicine its foundation.
Mahmud of Ghazni
Mahmud of Ghazni (971–1030 CE) expanded his rule across eastern Iran and beyond. Ibn Sina avoided establishing his career at his court. Later narratives turn this into a pursuit involving portraits and agents; the autobiography is much terser about the necessities that drove departure and travel. Political pressure is plausible, but the pursuit story belongs to the later tradition.
ʿAlā al-Dawla
ʿAlā al-Dawla Muhammad ibn Rustam Dushmanziyar, the Kakuyid ruler of Isfahan, provided Ibn Sina with the most stable and supportive patronage of his career. Under his protection from around 1023 CE until his death in 1037, Ibn Sina refined the Canon, completed the Shifa, wrote astronomical observations, composed treatises on music and language, and accompanied the ruler on campaigns. ʿAlā al-Dawla held a philosophical discussion group that Ibn Sina attended weekly. He treated the scholar as a companion and intellectual equal rather than merely a court physician.
The Legacy of Ibn Sina
The Canon reached Latin readers through twelfth-century translation and became an important part of medical teaching. Its authority was sustained by readers who explained, abridged and disputed it. Earlier medical syntheses already existed, and later physicians did not all use the Canon in the same way. Its history is a changing tradition of study, rather than six centuries of uniform obedience.
The Book of Healing gave philosophical readers another substantial inheritance. Discussions of the soul, necessary existence and the relations among the sciences passed into Arabic and Latin debates. The floating-man exercise concerns self-awareness; calling it an early version of Descartes’s method obscures its own questions.
Ibn Sina’s work depended on libraries, teachers, pupils, scribes and patrons. The biography reveals how fragile those arrangements could be. The imagined first-person book follows that dependence from Bukhara through court service and captivity to Isfahan and the final illness at Hamadan.
