Vein de Medina is a disease when a pimple appears on some part of the body, which swells and forms a blister; then the pimple breaks out and something red comes out of it, with a blackish tint, and it grows longer and longer. Sometimes it moves under the skin like a worm, and it seems that these are the movements of an animal and that this red vein is really a worm, so that some think that it is an animal emerging under the skin, and others believe that it is a branch of rotten and thickened nerve fiber. Most often, such a pimple forms on the legs, but I have also seen it on the arms and side; in children it often pops up on the side. If you pull this thread and break it, the danger and pain increase; however, the pimple hurts for some time, even if the thread does not break.
Galen says that he has not established anything clear and thorough regarding this disease, since he has never seen it. He also says that its cause is hot, bad, black-billed blood or burnt mucus, which becomes pungent due to the strong dryness of the nature.
Sometimes this disease is caused by water and vegetables due to their inherent special properties, and most often it originates from dry, parched foods. The sharper the matter from which it originates in the body, the stronger the pain.
Often, one person develops forty or fifty of these threads in different parts of the body, although they can be eliminated through treatment. This rarely happens in people with a moist body, who use a bath and consume moisturizing foods, as well as wine in moderation. Most often, such a disease occurs in Medina and is therefore classified as Medina, but sometimes it originates in the country of Khuzistan and in other countries. Many such cases sometimes happen in Egypt, as well as in other places.
To protect yourself from this disease in places where it occurs, and when eating foods that cause it, you should fight its cause. This is done by removing bad blood through bloodletting from the basil or from the jugular vein, depending on where the sore has formed; they cleanse the blood, for example, by drinking from both myrobalans, a decoction of bitter wormwood and especially kukai pills, as well as taking atriful prepared with senna and smoke, and moisturize the body with the help of moisturizing dishes, baths and other known methods of hydration.
At the first appearance of signs of illness, it would be correct to resort to cooling the organ through cooling and moisturizing medicines, for example, the well-known cold astringent juices along with sandalwood of both types and camphor after preliminary cleansing the body of matter. The vein is also pulled outward, allowing leeches to approach the sore spot. Of the ointments, a good ointment is made from sabur, sandalwood and camphor or from myrrh, flea plantain and fresh milk. If the vein does not return under the skin, but, on the contrary, begins to swell, then sometimes they delay its development, direct it back and reduce the danger by allowing the patient to drink daily, for three days in a row, at the dirham of sabur, or it is drunk on the first day of half a dirham, on the second day - dirham, and on the third one and a half dirham. The sore is lubricated with sabur or its hole is lubricated with sticky liquid from fresh sabur. The same is done when the vein begins to emerge. And if the vein, despite this, comes out further and further, then it is reasonable to prepare a stick for it, to which it can be tied, and then carefully, little by little, wrap the vein on this stick until it comes out all the way without breaking. It is best to take a piece of lead and wrap a vein around it, relying only on its weight when pulling; then the vein will gradually stretch out and not break. They try to facilitate its release by gradually warming and loosening the organ by pouring hot water, cooling mucus and emollient oils - cold or slightly warm, or from substances having the same properties.
Sometimes the vein comes out easily, but sometimes this does not make it easier to come out and you have to resort, for example, to mud cakes with wallflower or even jasmine or bana oil, or apply a Zift plaster. If the assumption suggests that the cut will allow you to remove the entire vein and nothing prevents this, you make a cut and remove it. If it is not easy to extract the vein by the method of pulling out mentioned above, and it is impossible to cut it out, then make it rot with the help of melted butter; it will completely rot and come out. But beware of taking sharp medicines; this sometimes leads to corrosive gangrene.
If you constantly lightly rub the edges of the sore with salt or gently rub it from behind, gently and carefully pulling the thread out of the hole, it will come out entirely, especially if you make a cut as far back as possible, insert a knitting needle under the vein and push out the vein, all the time lightly rubbing the sore with salt, while the vein comes out; if you act this way, it sometimes comes out entirely. If the vein breaks and hides, then in order to catch it again, a cut cannot be avoided; then it is carefully removed and the sore spot is treated with wound medicine.
