The ritualis required a freshly dead hexenbiest.

The suppressant required a dead hexenbiest, but not fresh.

Aside from those two specific potions, we know of no others which require adad hexenbiest.

Wesen have a use for organs of humans that the wesen council declared illegal.

Kenneth's body was useful to pin the ripper murders on. To say his body was more valuable after death would be a stretch.

If there's a potion that requires a dead royal, we haven't been shown it or told about it.

So no, syscrash53, there is no precedent on the show. Stefania believed Frau Pech would have murdered her, cutting out the middle womanso to speak. There's absolutely no evidence that Stefania is a hexenbiest.
