Constrictions, contractions and congestions run through Cactus. Determination of blood to the head, and coldness of the extremities. Or determination of blood to an organ, the chest, or the heart. There is never an equal circulation of blood in the body; it is spasmodic and irregular. Disturbed by contractions of circular fibres everywhere. When this comes in places where it can be felt; and realized by the senses, it is felt as contractions, as if caged in wires, and this gives us the key to Cactus. Where contractions cannot be felt, where there is no sense of feeling, we know that it goes on as a spasmodic condition of circular fibres; but these contractions that are felt are more upon the surface of the body, and in organs having circular fibers tubes and canals. They constrict, and this constriction is felt like a spasm. It has a sensation of tightness and constriction about the head, about the chest, about the attachments of the diaphragm, all over the abdomen. Contractions about the heart that are tonic in character, like a tight clutching; constriction. "Constriction felt about the heart." Constrictions and congestions: These constrictions are felt about the throat, in the oesophagus, causing a spasm; in the vagina, causing vaginismus and preventing coition. In the uterus it produces the, most violent cramps. Clutching, and constrictions, as it the uterus were grasped and held tightly, like a spasm. But at these times, when these constrictions take place, there are congestions. "Rush of blood to the part, with constriction." "Violent congestion of the uterus with constrictions. Rush of blood to the chest, as if the chest was filled with hot gushes of blood, with constrictions, and constriction of the heart." These peculiarities run through Cactus more markedly than any other remedy. Many remedies have similar things now and then, but in Cactus it is common; it is the nature of Cactus to constrict, to cause constriction in places where it has never been felt, and never been thought of. Constrictions of the whole body, as if the body was held in a wire cage. Constrictions of the scalp, of the skin, growing tighter and tighter. Violent congestions that come on suddenly. Congestion of the brain, with hot head, flushed face. At the beginning of complaints, at the beginning of pneumonia; congestive chill with hot head and cold body (like Arn.) with violent constrictions and tightness, as if the head were pressed, as if the membrane of the brain were too tight, as if the brain were covered with a tight cloth, and were being screwed tighter and tighter. Uniform tightness of an organ, as if it were being bound tighter and tighter, but in tubes and canals it is a constriction of a particular part. Many times like as if tied with a string. Constriction, like hour-glass contraction, in the uterus. It has inflammations, congestions, rush of blood to the part, gradually progressing to inflammation, and infiltration. Inflammation of various parts. It has rheumatism. It is a remedy very useful in gouty constitutions; very useful in acute inflammatory rheumatism; and in this instance the congestion is in the joints that happen to be affected. And then again the constriction, as if tied with a tape, or as if bandaged. Tightness, tension, pressure, are involved in that thought. It has such a prolonged determination of blood to the heart that the heart finally becomes disturbed in its function, disturbed in its tissues; and it has a profound curative action upon the heart and even cures organic heart diseases, such as are produced from this cause, conditions coming on from congestion, or coming on through congestion in rheumatic constrictions, where the rheumatism has left the joints partially and the heart has become involved, and there is constriction of the heart. Various efforts have been made by provers, and by patients, to describe the constriction of the heart. It is sometimes described "as if grasped with an iron hand." It is only to illustrate the tenacity of the constriction. In these rheumatic troubles when the joints have ceased to be affected and the heart becomes affected with this chronic congestion and enlargement, we have enlargement of the valves so that there are murmurs, the head is hot, and the patient gradually emaciates. Kidney troubles will come on; the heart grows weaker, and then dropsical conditions set in that is, the course of Cactus. Towards the last, cardiac affections, along with kidney affections, with emaciation, and then swelling of the hands, and feet. That is the very nature of Cactus, and you will not find any medicine in the whole Materia Medica that reads like it. There is nothing to compare with it in the intensity of these symptoms. All these things that I have described seem to turn upon these words, congestion, constriction and contraction. The pains in Cactus are violent, no matter where they occur. They compel the patient to cry out, and the pains are clutching pains, constricting pains; they often feel like tearing pains; but there is always that idea of clutching. Suppose you should tie a tape round a violently congested organ, and tie it tighter and tighter. It seems to me that is about the kind of suffering the patient has with that constriction of a congested organ. Pains and spasms: Pains in congested parts; pains in sore parts. Tearing; constricting, cramping, when pains occur in the intestines they are constricting, but when the pains are in the long muscles they are not the constricting pains, for it is not the circular fibres then but the long fibres that contract, and we call them cramps. Cactus produces some spasmodic conditions in long muscles, but not to any great extent. In Bell. especially, and also in many of those medicines that have this nature of cramping, and constricting and contracting of circular fibres, there is convulsive tendency. The violent congestion of the brain in Bell. will commonly be attended with cramps in the extremities and convulsions of the muscles all over or in parts. Not so with Cactus. Violent congestion, and he grows stupid under it. Congestion of the brain, first with very red face, then darker from the venous stasis, and then stupor. He grows sluggish under the cerebral congestion. The mental state is that of fear and distress, because of the intensity of the suffering. The patient has never felt such suffering, and he does not see what it can all mean. So much suffering, such violent suffering, such sudden suffering, such cramps, such tearing, such constriction. When this constriction comes in the heart, and about the chest, it makes the patient think he is going to die, and he is at once, struck with fear, and it is depicted upon the face. He fears death, and it seems he is going to die, his pain is so intense. But with this intense pain he has nothing of the anxiety we find in, Aconite, which has a similar constriction of the chest and constriction of the neck. The violent choking in Aconite makes him fear he is going to choke, to death, and the anxiety is awful. It is not so intense in Cactus. Screaming with pains is a common thing in Cactus.
