This remedy is an antipsoric, a deep-acting remedy. It runs very close to Calcarea, but is milder in its action. It has the same exhaustion from exertion, dyspnoea, sweating and coldness that we find in Calcarea. What will forcibly call your attention to a remedy will be the curing of a bad and typical case. I remember the first time my attention was decidedly called to Cistus. I had put it on my list to study from time to time and had come to the conclusion that it was only a side issue, until a young lady of nineteen years of age fell under my observation.
