China officinalis
Cinchona officinalis · Peruvian bark, cinchona bark, Jesuit’s bark, china bark, calisaya bark, loxa bark, red bark, yellow cinchona. · Plant · Rubiaceae
China is thought to work best for idealistic, artistic people. Despite problems articulating their feelings, they prefer meaningful talk to trivial chat, but their own intensity often tires them, causing irritability, laziness, depression, violence, or intolerance. Easily offended, they may feel paranoid and mistreated, or that they have been born unfortunate, as if the world is hostile to them. A highly active imagination can lead to a preoccupation with future plans and to egocentric, heroic fantasies that later cause embarrassment.
Physical symptoms may be linked to weaknesses in the liver and digestive system and generally include a dislike of butter and other fatty foods, and cravings for alcohol and foods that are sweet or spicy.
The remedy is used for exhaustion following illness or extreme fluid loss. It is also given for fever, insomnia, gastric upsets, and headaches.

Now we shall take up the study of Cinchona, or China. Persons who have suffered much from neuralgias due to malarial influences, who have become anaemic and sickly from repeated haemorrhages, are likely to develop symptoms calling for China.
China produces a gradually increasing anaemia, with great pallor and weakness. It is sometimes- indicated in plethoric individuals, but this is the exception, and even in this class we find that the symptoms are tending towards the cachectic state, which is avoided by the prompt action of the remedy.
Throughout the body there is a gradually increasing sensitivity, a gradually increasing irritability of the nerves; the nerves are always in a fret, so that these people will say:
