The stomach is treated with drinking medicines, medicinal bandages, pouring water in which medicines were boiled, ointments, rubbing in oils and plasters made from wax boiled in water in which medicines were boiled. Ointments and medicinal dressings work better than pouring: pouring has a weak effect. Know that it is easier to treat a disorder of nature that has arisen in the stomach in relation to both of its effective qualities, for it is easy for us to obtain medicines that resist these qualities and are very strong, but to treat a disorder of nature that has arisen in it in relation to two of its ineffective qualities is more difficult, especially a dry nature, for each of these qualities is opposed by a weakly acting force. The time required to warm a cold stomach is equal to the time required to cool a hot stomach, but the danger in cooling is greater, especially if any organ adjacent to the stomach suffers from a cold disposition or weakness. The danger from moisturizing and drying is the same, but the time required for moisturizing is longer.
Know that when diseases of the stomach arise due to matter and matter gives the doctor difficulty, then there is nothing more useful than iyarajas: they are better than all medicines in helping to correct the stomach and make its inherent actions perfect. One should not rely on Iyaraj when the disorder of nature takes place without matter: it is harmful to a hot and dry nature, and stronger medicines can be found for a cold nature.
When you empty your stomach of the juice that has poured there from another organ, then after that strengthen it so that it no longer accepts such juice; Bandaging and warming the extremities helps to retain substances pouring into the stomach. Drinking from the soporific poppy also brings great benefits when the juices are hot, and if the juice is cold, then the adhesives needed after this are mastic, small rose cakes, dried mint, raw aloe, cloves and the like. If the juice is hot, then they treat with thickly brewed fruit juices, cold cakes made from roses and bamboo nodules, and similar means. If in the area between the stomach and liver there is hardening and thinning, which we mentioned above, then barley water is prescribed for nutrition and as a medicine, which is drunk gradually, day after day, increasing its amount from ten to twenty and even up to one hundred dirhams and even up to one rittl during the day, until the patient is strong enough to drink this amount in one or two times. You should never bring any emptying equipment near such patients or open their blood.
Lozenges prescribed for this disease. They take mastic and cakes of rose for three dirhams each, amber, dry mint, marmahur and raw aloe for two dirhams each, and give it to drink with old wine or maybih.
To cleanse the stomach and remove juices that have accumulated, stuck or been absorbed into the stomach cavity, you should use medicines that pass no further than the stomach and the ducts close to it and do not reach the vessels distant from it. If they do not work immediately, then give them a second time; this is better than emptying when there is no need for emptying. In case of stomach diseases, one should take into account the quality of stool and urine. If you see that they are becoming good and improving, it means that the stomach is heading towards correction. When treating the stomach, even if it is hot, you should not administer very cold substances, for example, very cold water, especially if the patient is not used to it. When using dissolving medicines, which generate a lot of excess, you cannot do without, as you know, astringent and strength-preserving substances.
