IK this thread is a bit dead, but this seemed the best place to put this.
In regards to Licorice, it blocks 11B-HSD from converting Cortisol to Cortisone. Now, this is really important for its role with Aldosterone. Cortisol binds to the GR, but also to the MR. Without 11B-HSD, Cortisol would overwhelm the MR and lead to a chronic state of pseudo-aldosteronism and tank k+ / do the other things that happen on licorice. 11B-HSD is present by MRs so that it can attempt to block cortisol action on it. What if licorice suppressing 11B-HSD induces the body to freak out and increase 11B-HSD expression? Then you'd stop the licorice, and bounce back because you would have lowered Aldosterone on the Licorice, and now you'd also block more cortisol on the MR. This might be another factor that allows a snap-back after Licorice treatment.
