pesachim 110

BEWARE OF EVEN DRINKING

is the king of the demons dangerous?
Yosef the Demon taught how men (not ordinary women) should be careful about drinking in pairs. even numbers can be fatal.
but not things that are man-made, just things from heaven. like wine, and beer, and women....

(more demons! strange tales from Yosef the Demon who says that Ashmedai, king of the demons, is only a king not harmful... but others disagree. kings are a capricious moody bunch. Other stories on this page about witches, and ex-wives who use the dangerous double drinking to cause harm.
some interesting 'facts' about the dangerous pairs - only pairs of heavenly made things are fatal, not man-made items. And women aren't affected. Apparently demons aren't interested in how much women drink. and demons only bother you if you are bothered about them.... so be like a woman and turn your back to the demons and drink as evenly as you like)

shabbat 109

removing evil spirits and harm

the evil spirit on the hands that can be removed with careful washing,
eye-shadow that cause the Daughter of the King to pass by
and
a log of 40+day old urine will keep witchcraft (and everyone else) at bay.

and all these harmful evil spirits are female...

(this page of the talmud discusses various remedies and cures. taking medicine for non-fatal aliments is not permitted on the sabbath. for english translation of this talmud page, see here)

shabbat 81

what they used to use for toilet paper

but it is dangerous to just take anything that comes to hand.

(when determining what size stone one is liable if carry on shabbat, there is a discussion about carrying stones used to clean after defecation. shards of earthenware were prohibited. one opinion is that they were forbidden due to witchcraft.. for english translation of this talmud page, see here)

brachot 53

when making the blessing of distinction and difference
the eye must be able to differentiate between 2 objects that can be seen

and know the origin of the scent that cannot be seen

after all. those sweet spices could have been used by the witches.
