If you notice that a person is becoming rancid inside, then arsenic is a good remedy for the fats that he has inside that he is not processing. Arsenic fights against fattening and strengthens the astral body. And the result is that the person can fight this rancidity. These are things that are extremely important. If a person shows an inclination within themselves to be unable to overcome their putrid protein through the etheric body, then some compound with copper usually has an extremely strong effect on the person as a remedy. Copper is effective when the lower abdominal diseases, intestinal diseases, are directly caused by the protein. But if you notice that something is making itself felt through the mouth, through the sense of taste, it does not help to give the person copper, but arsenic is needed because you first have to strengthen the astral body. So it is not enough to simply state that this or that disease lies in this or that part of the human being; instead, one must know where they come from. Whether they come from rotten protein in the intestines or from fats that have gone rancid, which in turn affect the intestines and stomach through the taste of the mouth.
