Unknown Mixture
Unknown mixture is a potion in The Witcher 2 whose data shows no listed effect beyond its side costs. Drinking it adds 5 Toxicity, and its effect lasts only 15 seconds, far shorter than standard potions such as Tawny Owl.
It weighs 0.2 and has a base value of 1 oren, the lowest of any potion in this list. In practice it is little more than a curiosity, with nothing in its stats to make it worth drinking.
