Mucous membranes: Catarrhal condition of all mucous membranes. Gastro-duodenal catarrh, ending in jaundice. Old liver subjects with jaundice. They have lived for a long time under the influence of the malarial miasm. Feeble, sensitive, anemic. We see such cases in the South and Southwest, and long the Mississippi Valley.

Periodicity: is regarded as the most important indication for China, but it is a mistake. Periodicity is the symptom upon which Quinine is given. China has periodicity, but in no greater degree than many other remedies and is not so frequently indicated as routine prescribers suppose. Allopaths give Quinine whenever there is any periodicity in complaints. Still periodicity is a strong feature in this remedy. Pains come on with regularity at a given time each day. Intermittent fevers appear with regularity and run a regular course.

A part of this periodicity is an aggravation at night, and sometimes sharply at midnight. In colic that comes on regularly every night at 12 o’clock, and it may be, perhaps, a week before you, suspect it to be a China colic. A lady had colic and bloating of the abdomen every night at 12 o’clock.

After suffering many nights a single dose of China, prevented any further trouble. Haemorrhage from the nose coming on with regularity. Diarrhoea at night. Several gushing, black, watery stool; during the night; in the daytime, only after eating.

There is a general aggravation after eating. Remember that this is a chilly patient, sensitive to draft, sensitive to cold, whose complaints are brought on by being exposed to cold air; sensitive to touch, sensitive to motion. Extreme irritability of the tissues.

China is indicated in conditions following the loss of blood and other animal fluids; as, for instance, in those who are suffering from sexual excesses, from secret vice. They have become feeble, sleepless and irritable.

There is weakness and general coldness of the skin; twitching and jerking of the limbs; drawing and cramping in the muscles; chronic jerking; epileptiform convulsion; paralytic weakness; rush of blood to the head; ringing in the ears; darkness before the eyes; fainting on the slightest provocation.

Mind: Such is the China cachexia, and with this in view, the mental state will scarcely be a surprise to you. It is just such as you would expect in this nervous, sensitive patient. Weakness of mind. Inability to think or remember. Full of fear at night. Fear of animals, dogs, of creeping things. Wants to commit suicide, but lacks courage. Gradually the mind grows weaker, he uses wrong expressions or misplaces words.

Lies awake at night making plans, theorizing, building air castles, thinking of the wonderful things he is going to do some day. In the morning he wonders how he could have thought such foolish things.

After sleep his mind is clear and he looks more philosophically on the affairs of life. Unable to entertain any mental proposition that, means work. He dreads work. He is apathetic, indifferent, low spirited, silent, disinclined to think. He is unable to control the mind, to make it do what he wants it to do. You see it is not as yet a real insanity.

This state of mind comes on after haemorrhage. Insomnia after haemorrhage. A woman, after having suffered great loss of blood, will be sleepless night after night.

After hemorrhage we may have dizziness. it is a natural consequence; dizziness and fainting. But ordinarily, after the proper diet for a few days, these symptoms will have disappeared. With the China patient they go from bad to worse. The woman after severe haemorrhage does not make blood. There is mal-assimilation, and the vertigo persists for days and weeks. China will restore order.

James Tyler Kent
James Tyler Kent (1849–1916) was an American physician. Prior to his involvement with homeopathy, Kent had practiced conventional medicine in St. Louis, Missouri. He discovered and "converted" to homeopathy as a result of his wife's recovery from a serious ailment using homeopathic methods.
In 1881, Kent accepted a position as professor of anatomy at the Homeopathic College of Missouri, an institution with which he remained affiliated until 1888. In 1890, Kent moved to Pennsylvania to take a position as Dean of Professors at the Post-Graduate Homeopathic Medical School of Philadelphia. In 1897 Kent published his magnum opus, Repertory of the Homœopathic Materia Medica. Kent moved to Chicago in 1903, where he taught at Hahnemann Medical College.
