In his medical writings, Maimonides described many conditions, including asthma, diabetes, hepatitis, and pneumonia, and he emphasized moderation and a healthy lifestyle. His treatises became influential for generations of physicians. He was knowledgeable about Greek and Arabic medicine, and followed the principles of humorism in the tradition of Galen. He did not blindly accept authority but used his own observation and experience. Julia Bess Frank indicates that Maimonides in his medical writings sought to interpret works of authorities so that they could become acceptable. Maimonides displayed in his interactions with patients attributes that today would be called intercultural awareness and respect for the patient's Autonomy. Although he frequently wrote of his longing for solitude in order to come closer to God and to extend his reflections – elements considered essential in his philosophy to the prophetic experience -he gave over most of his time to caring for others. In a famous letter, Maimonides describes his daily routine. After visiting the Sultan's palace, he would arrive home exhausted and hungry, where "I would find the antechambers filled with gentiles and Jews … I would go to heal them, and write prescriptions for their illnesses … until the evening … and I would be extremely weak."
