Commentary for Avodah Zarah 56:2

Cures for hemorrhoids.

My assumption with the notion that kidneys are a cure for earache is that this is a result of the similarity in shape. But that’s just a guess.

All agree that it is permitted to “restore the ear into its proper position” which means to fix a dislocated jaw. However, they disagree with regard to whether it is better to do so with medicine or with the hand. Those who prefer the hand would say that taking medicine is a rabbinic prohibition and therefore should be avoided. Those who prefer the medicine would say that resetting the jaw by hand might cause injury, and it is prohibited by the Torah to cause injury.

An eye that got out of order seems to refer to an eye that is about to pop out of its socket. The medical treatment is to apply blue eyeshadow. The Talmud rules that this injury is so dangerous that the dyes may be ground even on Shabbat and they may be carried through the public domain.

Great story!

Sadly, the rabbis learn how serious eye injuries can be from the maid servant who cries out in pain, but no one pays attention to her because they do not want to transgress Shabbat.

The Talmud distinguishes between eye injuries that are threatening and therefore can be healed on Shabbat, and those that are not and cannot be healed on Shabbat.

This is a list of food or activities that are in some situations beneficial to one’s health, but in the opposite situations are not.
