You should carefully study what is said about asthma and breathing and then move on to other diseases that have a common cause with asthma. The lungs are sometimes exercised by increasing the volume of the voice or by vigorously exhaling air in order to make the excess in them more rarefied. There is a special form for the administration of breast medicines: in most cases they should be used in the form of pills and lick medicines, which are kept in the mouth, swallowing little by little what dissolves, so as to prolong the time of their passage in the vicinity of the tube. This is repeated several times, and the medicine reaches the tube and the lungs, especially if the patient lies on his back and the muscles near the lungs and tube are relaxed. The closest direction to which excess can be diverted from the lungs is the side adjacent to the esophagus. Therefore, vomiting is often beneficial if there are no obstacles.
