42:83 · A sign for camphor in early chemistry. Camphor was used as a medicament. One of its uses during the nineteenth century was to cause convulsions and unconsciousness in schizophrenics or severely depressed patients. Later the psychiatrists started to induce convulsions and unconsciousness by means of heavy doses of insulin, or very strong electric shocks to the brain. As with the camphor- induced convulsions this treated the symptoms but not the disorder itself.
