[A few references to potions from Goethe’s Faust:]Goethe’s Witch’s Kitchen:
“With this drink in your body, soon you’ll greetA Helena in every girl you meet.”
[A potion is given to Gretch to give to her mom. But the difference between a medicine and a poison, they say (Paracelsus said), is in the dose ( target=”_blank”>https://en.wikipedia.org/wiki/The_dose_makes_the_poison). It doesn’t go well. It kills her:]
Margaret. Ah, if I only slept apart!For you I’d gladly leave the bolt undrawn tonight,But then my mother’s sleep is light;And were we found by her, dear heart,I would fall dead upon the spot!Faust. No need of that! You angel, fear it not!Here is a little phial Only threeDrops in her drink, and pleasantlyDeep slumber will enfold her like a charm!Margaret. For your sake what would I not do?I hope it will not do her harm!Faust. If so, my love, would I thus counsel you?
