I use the "throw item" option in the Radial.
Press R1, look for a green icon of a hand throwing a rock. Looks like this:

When throwing potions, throw on the ground, and not on your companions/allies:

When done correctly, your companions will be highlighted, but not show disadvantage/advantage percentages.

DO NOT throw on the character, because you have a chance to miss. You also have a chance to bludgeon your companion on accident. When you throw on the ground, your friends will be standing in the healing liquid, AND you have the chance to heal more than one character at a time, with just one healing potion. Gale and Shadowheart are both at max health, otherwise they both should have been healed.
