Of course the flipside of the coin is that there is friendly healing too. I haven´t tried it, but if I understand correctly you should be able to heal multiple members of your crew if you throw a healing potion between them when they are huddled close together.
No, BUT you can heal two people in a single round of combat with healing potions.
You place a healing potion next to each person, then you make sure you have a weapon in each hand. Then you hit the first healing potion with your main hand attack and hit the second with your offhand attack. This ENORMOUS exploit allows you to get two downed players back on their feet in 1 combat round.
Honestly someone should fix it.
