"According to an old tale, this potion was first made by dryads from the forest of Brokilon. The formula was obtained by the druids of Maribor Forest, who then passed it on to their brethren in other corners of the world. The formula also reached Kaer Morhen, where the practical-minded witchers began producing the potion using ingredients obtained from monster carcasses."
