Johann Peter Frank Recognizes Difference Between Diabetes Mellitus and Diabetes Insipidus

Frank is without doubt one of the most influential figures in the early history of public health and community medicine.

In addition to his System, Frank wrote a seven-volume textbook of internal medicine and made important clinical discoveries, including the distinction between diabetes mellitus and diabetes insipidus.

Like Aretaeus before him, Avicenna recognized a primary and secondary diabetes. He also described diabetic gangrene, and treated diabetes using a mixture of lupine, trigonella (fenugreek), and zedoary seed, which produces a considerable reduction in the excretion of sugar, a treatment which is still prescribed in modern times. Avicenna also "described diabetes insipidus very precisely for the first time", though it was later Johann Peter Frank (1745–1821) who first differentiated between diabetes mellitus and diabetes insipidus.
