Why is there a snake attached to medicine on hospital signs, universities and religions like Hinduism? Watch this video.

Christianity is the only religion that speaks against the snake throughout the Bible because of the Greek myth being false about the snake giving healing herbs. Silly eh? Why a snake? I think because Satan can even pretend to be healer. Hence, the phrase, "snake oil". Satain's oil will even try to copy God's holy annointing oil of the Holy Spirit.
