Larian Studios Forums Divine Divinity (English) Help/Tips/Tricks Strange potions

I've got two potions in my inventory, and I don't even know where they come from, he he. One is called Super Drug, a big cyan super bottle and the other is a Purple Potion, a rather strange and unique thingy. Oh, and the strange spice from the castle's cook, which I know is an invis potio sort of. Are they of significance, a quest or just there? <img src="/ubbthreads/images/graemlins/rolleyes.gif" alt="" />

Super drug: +100 poison resistance and -100 spiritual resistance, temporary.
Spice: just an invisibility potion
Purple drug: gives back +20 health and mana, selling it is more worth
Kiya

Just my guess: Spice and purple potion could've been part of a quest taken out of the game.
