Polonca Kovačová is one of the most popular Slovenian authors of children's books. The little witch Lenka moved in with a mouse family and other animals and initiates them, especially the mouse Lolka and his little sister, into the secrets of the apothecary art. He discusses 34 medicinal herbs with them and tells the most important things about each one from a professional point of view, and connects it all with events, conversations, funny situations, which also use linguistic comedy, so that the little reader does not even realize that he is actually learning. The magical atmosphere is completed by the charming illustrations of Ančka Gošniková Godecová.
