Hyoscyamus is the best remedy for those with paranoid traits and behavioral problems. The typical Hyoscyamus pattern is incoherent, excited behavior, muttering, and obscene sexual exhibitionism. Laughter at inappropriate times is common, as is a sense of being ostracized in a private world.
In addition, Hyoscyamus is used for physical conditions associated with involuntary twitching, such as delirium, and for fits of dry coughing. Homeopaths may prescribe it for certain types of convulsions, such as petit mal, epilepsy, and, in children, febrile convulsions with a rapid rise in temperature. In some cases, the remedy may be given for schizophrenia and Parkinson’s disease, if accompanied by marked withdrawal, obscenity, and inappropriate laughter.

Characteristics
Hyoscyamus ("Hog-bean") is nearly allied to Belladonna botanically, and in pathogenetic action the two drugs are much alike in their main features.

Hyo. is found growing on old rubbish …
