This book which consists of nine books (plants, elements, trees, stones, fish, birds, animals, reptiles and metals) can be considered the foundation of Hildegard's medicine. Hildegard explains the nature and benefits/dangers of each creature and element to human beings. Physica is very easy to read unlike her books on theology which require background knowledge of Christianity. As a naturopath ho practices Hildegard's medicine, I refer to this book quite from time to time.
