Psorinum
Henry N. Guernsey著 — Key-Notes to the Materia Medica
The symptoms of this drug are very closely allied to those of Sulphur; if the latter appears to be indicated, but fails to cure, study up Psorin.
Dry, lustreless, rough head of hair. Eructations tasting like rotten eggs; stools (diarrhœic) smelling like rotten eggs. Debility remaining after acute diseases.
