Seems more logic to me than drinking it actually. If the liquid itself is healing, why not to apply it to the hurted area instead of drinking it, if it is not something like meds that have to go through resorbtion to bloodflow to take effect.
bahahaha I never even thought about the glass from the bottle lmao. I just always remember seeing in Final Fantasy (especially 10) character's throwing items into the air to use them on other characters, so I wanted to capture that. The glass would hurt, tho lol.
But yeah, drinking would take more time to take effect!
xD
