Shiavault - a Vault of Shia Islamic Books Hadith of Halila Supplement 5 What you say, said he, was already known to me but we physicians hold the opinion, that the person who invented the science, performed postmortem examinations, when the patient was not cured of his disease, and thus examined the blood vessels passages and places and located the traces of the medicines.
Do you not know, I asked, that the medicines taken internally circulate with the blood throughout the body, and become mixed up with it? "Yes I know it, he replied. "Don't you know, I asked again, that when a person dies, his blood thickness? Yes it does, he replied. Then, I asked, "How did the physician examine the medicine, when it was clotted in the blood, for all trace was surely lost, and in such a state could not be analyzed properly?" I am at my wit's end now," he said.
Again tell me, how the people were able to now the beneficial effects of the roots and plants they had investigated and their locations? How did they learn to analyze and mix them together, ascertain their respective weights, and discover the need of gall bladders and stones in certain medicines? You have discussed the subject with such perfection, said he, that I have neither the imagination nor thought nor wit to find a way of properly answering your question.
As these prescriptions have not invented themselves, they must have been invented by some one else and that same one else must have acquired a thorough knowledge of the natures and qualities of the items he had laced in such order. Will you kindly explain to me how the people were able to know those medicines that were beneficial to health, and how they could investigate these things in every part of the world?
Since you wish me to explain it to you, said I, I shall give you an illustration, and discuss it in such a wax that you will easily learn who the inventor of medicine was, who created the various kinds of plants and fruit? And who made the body and blood vessels, which carry the medicine through it to its affected parts. If you will do so, he said, I shall be very glad indeed. Supposing, said I, a certain man had planted a garden surrounded by a wall to protect it from outside harm.
Do you not think the owner would know every tree planted therein and its position?
