In the Early Middle Ages, Benedictine monasteries preserved medical knowledge in Europe, translating and copying classical texts and maintaining herb gardens.[20][21] Hildegard of Bingen wrote Causae et Curae ("Causes and Cures") on medicine.[22] In the Islamic Golden Age, scholars translated many classical Greek texts including Dioscorides into Arabic, adding their own commentaries.[23] 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.[24] Avicenna included many plants in his 1025 The Canon of Medicine.[25] Abu-Rayhan Biruni,[26] Ibn Zuhr,[27] Peter of Spain, and John of St Amand wrote further pharmacopoeias.[28]
