[rolls dice] like goat piss and cinnamon.
I've been planning to do something like this for a while now. Here's a short list of some alternate 'potions' for D&D. All follow the normal rules for potions as far as usage and duration and effect. Only the form has changed.
Xi Wang Mu's Peaches of Immortality/Apples of Idunn: potion of longevity
Egg Shen's Steaming Gourd: potion of heroism
Gummi Berry Juice: potion of giant strength (unless you're a Gummi Bear, then it's a potion of jump)
Black Lotus Flower: potion of poison
Atalanta's Golden Apple: potion of speed
Rapunzel's Tear: potion of cures (or specifically cure blindness)
Got more? Feel free to add to the list in the comments.
