I've been thinking how this would work in HQR, and is a shoe-in for the advanced game. Even if I then have to order an extra deck of cards

So, I'd do it like this...
Calming Brew
Discard: Restore up to one red die of lost Mind Points.
Cast, Discard: Roll two red dice, and discard the lower roll. Recover lost Mind Points up to the number rolled.
Discard: Re-roll one Test of Will
Discard: Ass one white die to your Wisdom until the start of your next Activation.
Essence of Warmth
Discard: Bearer or target adjacent figure recovers up to one lost Body Points, and an additional Body Poiint if they suffered any Ice damage this turn.
Cast, discard: Bearer recovers up to two lost Body Points, and two additional Body Points if they suffered any Ice damage this turn.
Potion of Healing
Discard: Bearer or target adjacent figure recovers up to four lost Body Points
Cast, discard: Bearer recovers up to six lost Body Points
Potion of Regenration
Discard: Restore up to one red die of lost Body Points.
Cast, Discard: Roll two red dice, and discard the lower roll. Recover lost Body Points up to the number rolled.
Rejuvination Salve
Discard: Bearer or target adjacent figure recovers up to two lost Body Points
Cast, discard: Bearer recovers up to three lost Body Points.
Restoration Draught
Discard: Bearer or target adjacent figure recovers up to one lost Body Point and one lost Mind Point
Cast, discard: Bearer recovers up to two lost Body Points.
Cast, discard: Bearer recovers up to one lost Body Point and two lost Mind Points.
Revitalisation Potion
Discard: Bearer or target adjacent figure recovers up to six lost Body Points
Cast, discard: Bearer recovers up to eight lost Body Points
Tonic of Renewal
Already maxes out both, so no change
Venom Antidote:
Discard: Use only when you lose Body Points to Poison Damage. Recover up to two lost BP.
Cast, Discard: Use only when you lose Body Points to Poison Damage. Recover up to four lost BP.
I went for "cast" action as it's a single icon, is esoteric a set of acions enough to match, and also means teh Wizard is pouring his own power in in those cases he's using a bonus cast from the Rod of Recall, etc.
