There is a difference between Rosalee's potions and Hexenbiest's. Rosalee's exploited the physicology of wesen with herbs, but lacked the magical properties. Its sort of a mysterious, loosely scientific bit of chemistry. Hexenbiests were required for anything producing a change that would seem overtly magical. Rosalee stopped a girl from experiencing  woges but turned her green as an side effect. weird but possible. Frau Pech outright switched form with Adalind. Adalind was also necassery for the protection powder made by Rosalee implying the magical element wasnt already there.
