Camphora officinalis
Cinnamomum camphora · Plant · Lauraceae
Camphora Officinalis is the supreme remedy for sudden collapse, shock, and states where the vital force has been overwhelmed, characterized by icy external coldness with paradoxical aversion to covering. Scrofulous children and weakly, irritable blondes are most affected. It corrects spoiled cases and antidotes most vegetable medicines. The digestive tract, cerebrospinal nerves, urinary organs, and nose are primary spheres of action.

Camphor
Hahnemann says: "The action of this substance is very puzzling and difficult of investigation, even in the healthy organism because its primary action, more frequently than with any other remedy, alternates and becomes intermixed with the vital reactions (after effects) of the organism. On this account it is often difficult to determine what belongs to the vital reactions of the body and what to the alternating effects due to the primary action of the camphor."
Pictures a state of collapse. Icy coldness of the whole body; sudden sinking of strength; pulse small and weak. After operations, if temperature is subnormal, low blood pressure, 3 doses camph. 1x, 15-minute intervals. This condition is met with in cholera, and here it is that Camphor has achieved classical fame. First stages of a cold, with chilliness and sneezing. Subsultus and extreme restlessness. Cracking of joints. Epileptiform convulsions. Camphor has a direct relationship to muscles and fascia. In local rheumatic affections in cold climates necessary. Distention of veins.

The camphor bottle is, a great mischief in the house, as camphor antidotes most of our remedies. Camphor in potentized form will cure many complaints.
It is suitable in some acute complaints attended with nervous excitement, even to frenzy, with spasms and convulsions and finally exhaustion. The Camphor state is one of convulsions or coldness.
In the most acute period of the Camphor excitement, the excitability and frenzy of the patient are extreme, or he goes into the other extreme, in which the irritability is lost and there is loss of sensation, unconsciousness and coldness.
The two extremes may be seen in one patient, one earlier and the other later. He may go from the extreme of mental excitement and violence to one of prostration and exhaustion, in which the body is blue and cold and yet must be uncovered.
