Ancient Medicine's Wisdom: Avicenna's Unique Treatment for Delusion

Avicenna, a Persian physician and philosopher from the 1000s, once treated a man who believed he was a cow and refused to eat. Avicenna arrived disguised as a butcher, claiming the "cow" was too thin to be slaughtered and needed to be fattened up first. The man began to eat, regained his strength, and eventually recovered from his delusion.
