The Incidence of Malvaria

Abstract

Hoffer and Mahon (2), using an extraction method of their own, have shown that certain compounds, separated on paper chromatograms, give a mauve colour. This colour comes on slowly over 30 minutes as a pink area which slowly turns mauve and then within a half to 1 hour has a typical mauve appearance. It then begins to fade and usually, within several hours, has gone. The presence of this mauve colour is taken as a positive indication of the presence of these substances, and Hoffer and Mahon state that the majority of schizophrenics have these unknown substances in their urine.
