Lachnanthes is a herb, growing in sandy swamps near the coast. The root is red and fibrous; leaves sword-shaped; stem hairy; flowers yellow, woolly. It belongs to the same order as Aletris, and is allied to the Irises.
There are headaches of great intensity; right-sided, as if split open with a wedge; with icy coldness of body; crying spells; after going to bed. Cannot get warm under a feather bed. A hot flat-iron > icy coldness of body. Lachn. has been largely used in cases of phthisis, often empirically, but sometimes on its indications.
Arthur Dalzell reports these cases (H. W., xxv. 158):
(1) Mrs. B., 43, fibroid phthisis of both lungs, collapse of right lower lobe. Great prostration; night-sweats; bowels alternately relaxed and confined; pain and stiffness in back; bruised all over; dry cough; roughness of throat, heart-sounds weak. Sleep bad owing to cough. Lachn. Ø, three drops every four hours. In three days the prostration was diminished, and the cough was much better, night-sweats and bruised feeling gone. From this time an emulsion containing cod-liver oil, liquor pancreaticus, eggs, cream and hypophosphites, and oil of Eucalyptus were given in addition. The case went on to recovery.
(2) Mrs. R., 45, in last stage of consumption. Right lung consolidated; left in cavities. Remittent fever. This patient had circumscribed flush on face; brilliant eyes; throat rough; felt bruised all over. Skin dry, except at night, when she had profuse perspiration. Constant dry cough. Muco-purulent expectoration. Lachn. Ø, five drops every three hours, relieved all the symptoms and procured euthanasia, the patient dying quite easily twelve days later.─Toothache is
