Perhaps you could say that by teaching his path he healed many people; but what I meant is more direct, physical healing: is there something written about that?
This article Ministering to the Sick and the Terminally Ill contains examples (references to suttas and the vinaya), certainly of caring for or ministering to people who are physically unwell.
There are also some accounts of people being "healed": see for example the paragraphs which begin,

As per a legend, Vaishali was once infested with plague and with Buddha's arrival, the plague ended. so there are many stories by later additions that Buddha was the direct cause for eradicating the plague. Some stories originating from SE Asia, one suggests that Buddha gave his Alms bowl to ven. Ananda to make holy water to sprinkle around town. This was probably untrue, given that in at least 13 sutta, Buddhda prohibits monks to make holy water. This one strange sutta doesnt fit in. Some scholars and experts believe that this story is the reason why you see today's monks sprinkle holy water in temples, especially in south east Asia countries.
