Can a scholar repeat healing hands every 10 minutes?


In adventures in Middle-Earth RPG, the scholar class has “Hands of a Healer” ability: “If you can touch a creature, you may expend one Healing Die per action, instantly granting them hit points equal to 1d8 plus your wisdom modifier…If instead you tend the creature for at least 10 minutes…, then you may multiply the 1d8 by your proficiency modifier… “

My question is: Can a scholar repeat healing hands every 10 minutes, spending more healing dices?
