Ibn Zuhr
Herbalism flourished in the Islamic world, particularly in Baghdad and in Al-Andalus. Among many works on medicinal plants, Abulcasis (936–1013) of Cordoba wrote "The Book of Simples", and Ibn al-Baitar (1197–1248) recorded hundreds of medicinal herbs such as "Aconitum", nux vomica, and tamarind in his "Corpus of Simples". Avicenna included many plants in his 1025 "The Canon of Medicine". Abu-Rayhan Biruni, Ibn Zuhr, Peter of Spain, and John of St Amand wrote further pharmacopoeias.
