This writing exhibits that he had lack of certainty and development in the art of medicine because physicians were unaware of facts that druggist was making the same drug or giving substitutions of prescription or giving them inaccurate compound as prescribed by doctors.
He was against the laws of the time that physicians were forbidding the preparation or dispensing the medicine. He said that preparation of medicine should not be trusted to the apothecary (who prepared and sold the drugs). Physician should understand how to prepare his own medicines so that he may know exactly what he is giving to his patient and be certain that there is no substitution or mistake in giving medicine.
Hahnemann said in this article "I repeat," he says, "from the very nature of the thing, I repeat, the physician should be prohibited, under the severest penalties, from allowing any other person to prepare the medicines required for his patients ; he should be required, under the severest penalties, to prepare them himself, so that he may be able to vouch for the result.
But that it should be forbidden to the physician to prepare his own instruments for the saving of life-no human being could have fallen on such an idea a priori."
It must be remembered that the man who opposes the art of apothecary compiled a very important book which gives principles and practice of pharmacy in detail.
And yet Hahnemann was forbidden to prepare or dispense his own medicines, and was driven from place to place because he attempted to do so. It is to be presumed that he really knew more about the business than most of the members of the Worshipful Company of the Apothecaries, who persecuted him.
He continues in this treatise as follows :
"It would have been much more sensible to prohibit authoritatively, Titian, Guido Reni, Michael Angelo, Raphael, Correggio or Mengs from preparing their own instruments (their expressive, beautiful and durable colors), and have ordered them to purchase them in some shop indicated.
By the purchased colors not prepared by themselves, their paintings, far from being the inimitable masterpieces they are, would have been ordinary daubs and mere market goods.
And even had they all become mere common market goods, the damage would not have been so great as if the life of even the meanest slave (for he too is a man) should be endangered by untrustworthy health instruments (medicines) purchased from and prepared by strangers.
