In medicine, the most outstanding work was done by Ibn Sina (Avicenna) whose encyclopedic writings 'Al-Shifa' and 'Al-Qanun fil Tibb' (The Canon of Medicine) were used as textbooks in Europe till the 18th century.
His most famous works are The Book of Healing, a philosophical and scientific encyclopedia, and The Canon of Medicine, a medical encyclopedia that became a standard medical text at many medieval universities and remained in use as late as 1650.
According to Huangdi Neijing (Yellow Emperor's Canon of Medicine) (Li, 2005), a TCM classic, the four seasons are featured by spring-birth, summer-growth, autumn-reaping, and winter-storing, which means the energy begins to grow in Spring, enhances fast in Summer, reaches its peak in Autumn, and decreases in Winter.
Ibn Sina's al-Qanun fi al-Tibb (The Canon of Medicine) was used well into the 17th century, and his Kitab al-Shifa, regarded as his magnum opus, remains an important work of philosophy and science to this date.
Included in the 14 manuscripts was the Canon of Medicine, by Ibn Sina; the third chapter of Sahih al-Bukhari; and a manuscript by the scholar Mohammed bin Ibrahim Al-Murtada, dating back to the year 1414.
