Organon §240

Persistent intermittent fevers may be due to psora.

If during an epidemic of intermittent fever, one or another patient is not perfectly cured by the homeopathic remedy found to be specific to that epidemic, this is always due to the hindrance of the psoric miasm (assuming the cure has not been hindered by the patient’s living in a marshy region). Such a case must be treated with antipsoric medicines until complete aid has been afforded.
