Book excerpt: When i had first read the second volume of Ibn Sina's study, "The Canon of Medicine", telling about which plant is recuperative and the applications of these plants internally and externally. Staying faithful to context of the book, submitting this book on behalf of the community was my biggest wish, during my 2 years. In order to bring simplicity, I worked meticulously to compile an index of plant names together with their latinized forms which are sorted in alphabetical order and also an alphabetical index of diseases, should be used. We can already see that the modern medicine finds out solutions to many diseases but nevertheless, there are still dozens of diseases which can not be healed. For instance, in this work, Ibn Sina explains the reason of why he has named a plant as "Swallow-Wort" as follows: Sometimes the newborn nestlings of a swallow suffer from blindness. It was observed that the mother squeezes the extract of this plant onto their babies' eyelids and then their eyes were healed..
