Rabbi Steinsaltz elaborates on the various proscribed medicines in the Talmud. He notes that most medicinal treatments recommended are verbal, with little from animal and mineral products. The medicine in the Talmud seemed to remain rather independent from medicine of its surrounding culture (e.g. four-humor theory of humorism). He suggests that this may have been one reason why Jewish doctors moved away from Talmudic medicinal recommendations. He also highlights certain medical achievements of Talmudic medicine.
