Tumors in the anus sometimes, but less often, begin on their own, and most often they are the result of cracks and itching or the result of blockage of the mouths of the vessels of the cones and the use of kidneys by cutting off the cones and sharp medications. If the tumors accumulate pus and begin to rupture, then there is a danger of fistula formation, so they are pierced until they are ripe. Bloodletting should be done at the onset of such tumors; sometimes it soothes the pain on its own. They are also covered with a plaster of white lead or smeared with egg white, which is ground with rose oil in a lead or tin mortar until it turns black. Or they take lead oxide - five dirhams, starch - eight dirhams, white lead - two dirhams, wax - three uqiyas, ghee - two uqiyas, duck fat - one uqiyah and sesame oil - a sufficient amount; to this add a little grape juice and wine boiled to a third. Duck fat is very useful in this case, just like well-baked bread and water, if you apply a medicinal dressing from it with egg yolk and rose oil. Or they take pure bread - rittl, saffron - one and a half ukiyya and use it with maybukhtaj. A bandage with bladder cherry is very good for tumors, as well as a bandage made from the yolk of baked eggs, which is kneaded with astringent wine and then mixed with wax and rose oil.
If the tumor has passed the initial stage and does not occur as a result of cutting off the cone, then a patch of diyahilun mixed with rose oil or a small basilikun patch with the yolk of a soft-boiled egg is applied to it. Onions and leeks boiled with medicinal chamomile, or a plaster of white lead with ammonium resin are also applied to the tumor. If the pain is very severe, then take fresh henbane leaves, squeeze the juice out of them, take a little henbane infusion and mix the juice with the infusion; then the bread is soaked in this liquid and a not very thick egg yolk or rose oil is added, and a plaster is prepared. Mild poultices and sitting in water in which painkillers such as flaxseed, marshmallow, marshmallow seed or mallow have been boiled also sometimes help. Shredded wheat mucus is added to the water. You should return to the paragraph on zahir, for there is indicated a good method of treatment for this case. If tumors located close to the anus are among those that collect pus, then you should quickly puncture them before they are ripe, so that the matter does not go deeper. This method is described from the words of Hippocrates.
