Trembling is a disease of the organs-implements, arising as a result of the inability of the driving force to continuously move the muscles and resist a certain gravity, which, moving the organ, prevents voluntary movement and interferes with it; thus, voluntary movements alternate with involuntary movements, or voluntary stops alternate with involuntary movements. Just as numbness is a damage to the sensory force, trembling is a damage to the driving force. The reason for this is rooted either in strength, or in the instrument, or in both at the same time.
When the driving force weakens from fear or from something very terrible, for example, from looking down from a height, from walking along the ridge of a wall, from talking with a noble and powerful person, or from other impressions that bind the mental forces, as well as from sadness, grief or joy, which upset the order of movement of the force, then trembling occurs. Anger often does the same, since it produces unevenness in the movement of the pneuma. Among the causes of trembling, which act by weakening the force, is frequent copulation on a full and full stomach.
As for the trembling, which depends on the instrument organ, it arises as a result of some relaxation of the nerve, not reaching the point of paralysis, and the organ cannot restrain itself from moving, as happens, for example, with copious consumption of wine, frequent intoxication, or excessive drinking of cold water. water or from drinking it at the wrong time. Trembling may also occur due to the formation of blockages in the organs due to significant congestion due to known causes, such as indigestion or neglect of exercise; then the driving force cannot completely penetrate the organ. The blocking matter sometimes breaks away from the walls of the passages and moves into them; in this case it sometimes allows the driving force to pass, and sometimes hinders it; It also happens that it doesn’t come off at all. Trembling can also arise from some drying out of the organ, which prevents it from freely bending.
And general damage is expressed in the fact that the organ receives some kind of damage, which then leads to damage to the driving force. This happens, for example, when an organ is struck from the outside by intense cold, or an animal bite, or an outpouring of juice, or intense heat, as happens with a burn, or something else, and then the driving force is damaged. Sometimes the driving force suffers a particularly intrinsic injury, and the organ also suffers a particularly intrinsic injury, and then the two injuries are combined.
Trembling sometimes occurs in all the limbs, sometimes in the arms, sometimes in the head alone, depending on the damage to one or another muscle.
The reason why trembling affects the arms and not the legs is this: either the cause is not rooted in the base of the spinal cord, but in the branches of the nerves going to the arms, or it is rooted in the base of the spinal cord, but the brain expels it to the nearest place and to the nearest side. Nature protects the spinal cord from penetration of this cause into it and prevents it from reaching distant places. Or the moving pneuma in the lower parts of the body turns out to be stronger and stronger, since these organs are more in need of a surge of pneuma and do not experience any significant influence of causes that are not very strong, and if the organ is affected, the pneuma turns out to be quite strong to suppress it. But this is not the case with hands.
The predominant cause of constant trembling is cold, for it weakens both the nerves and the pneuma, or moisture in the instrumental organ, which relaxes, but less than the moisture that produces paralysis. Hippocrates said: If a patient has trembling during a burning fever, then the clouding of reason eliminates it. Galen does not agree with this statement, but it is not one of those that has no basis.
Know that the most severe tremors are those that begin in winter on the left side of the body. Trembling in old people does not go away with treatment.
Signs. The signs of trembling are the above reasons, and they are obvious. Treatment. The same thing is done that is said in other paragraphs about paralysis, namely: opening blockages, eliminating relaxation, emptying, strengthening the nerves and moisturizing them, if necessary, strengthening the patient’s strength if the trembling is caused by weakening due to some illness, warm if it occurs from sudden cooling or cold drink; knead, rub, shake when necessary. According to what is set out in the general rules of treatment, patients should be bathed in hot spring water, for example, soda, arsenic, bitumen or sulfur; sea water is also useful.
If the trembling comes from cold water, then make a poultice with soda and mustard and rub the patient with bush oil, and if the cause was drinking too much wine, then perform a bowel movement and use mad cucumber oil and the like and constantly rub the patient with bush oil; Clover oil has remarkable properties in this regard. It is also useful to apply a medicinal bandage made from one fresh alfalfa. If the disease is caused by absorbed or thick juices or if it has become stronger, then cups are placed on the patient’s first vertebra and he is placed in a bath of heated oil or in a decoction of the animals mentioned in the paragraphs on paralysis, spasm and cusaz. At the end of the treatment, they give you to drink beaver stream with honey wine or with strong iyarajas; They also give pills prepared from rue and scolopendra. The hare's brains help a lot; they should be eaten fried. Those suffering from tremors can be helped by drinking honey wine with water in which marshmallow seeds and damuyun leaves have been boiled. They also give them squeezed juice of hemp-like saplings with water and apply the same treatment measures as for relaxation. If the trembling is characteristic only of the head, then a proven remedy is the use of Greek lavender in the amount of one or two dirhams, alone or with bitter iyaraj, in the form of pills or in honey wine. They also tried to give the sick kuqiya pills from one to two and a half dirhams to drink once every ten days.
Food must be digested quickly for them, and wine is harmful to them, just like cold water. Rainwater is better and less harmful for them, as is the case with any nerve diseases. Frequent bloodletting also harms them.
