The show made a point to highlight that Adalind was out of options in terms of suppressing or even permanently getting rid of the hexenbiest when she was with Rosalee. It's odd to say she cast a spell offscreen that gave her what she wanted and yet on screen there was nothing she could do to "fix" the hexenbiest problem. Her desperation was palpable for several episodes, if such a solution as @irukandji is suggesting was a possibility, surely the show wouldn't have kept it off screen indefinitely in some form or another.
This show deals with every plot point at face value, what you see is what you get. Look at the stick issue and the daft way they handled it when when all of S5 it was a big secret and with one line from Adalind in S6 it's no longer this major issue between them, in fact it sounded like she'd known about the stick for a while even though it was never seen on screen. The point is that if something is relevant to the story, the writers wouldn't keep it secret for long. Adalind’s fear of being the big bad hexenbiest prompted her secrecy and that was the issue between her and Nick, the reason for their trust issues and they dealt with that when she eventually confessed to Nick.
The show told us Adalind couldn't do away with her hexenbiest, nor could she suppress it, at least not without the primary ingredient of an old hexenbiest corpse and the show never changed this stance. If there's some third option of dampening the negative effects of the show, they clearly missed the opportunity to tell us between episodes 4x17 and 5x19 when it was relevant to the story for either Juliette or Adalind.
It turns out to lose the hexenbiest completely, all Adalind had to do was cross over to the other side and perhaps leave it there when she crossed back like Juliette/Eve did.
