A certain doctor came to one city, and at that time the daughter of the ruler of the city happened to fall into illness. And the wise but blind doctor promised that he would cure the girl with a tincture of herbs. Everyone was surprised how he understood herbs if he was blind. He, without looking at the grass, made a tincture and gave her to drink. As a result, she fell ill with a stomach ailment and died. And her parent forced the doctor himself to drink this potion. And he, having drunk, died.
And this awaits anyone who speaks and does without knowing the subject.
