In the winter of 1824, Hering’s right forefinger was cut while making a dissection on a dead body. The wound rapidly became gangrenous. In those days such wounds were mostly fatal. The routine orthodox medicines had no effect. Luckily for Hering and for homoeopathy, a disciple of Hahnemann named Kummer persuaded him to take homoeopathic treatment and gave him Arsenicum album. After a few doses he felt better and the gangrene healed completely. Hering was surprised and his interest in homoeopathy knew no bounds. He contacted Hahnemann for further instruction.
