Making and using rejuvenation potions is now supported! You no longer need to have food if you have herblore unlocked!
Currently requires herblore to be unlocked, future support to use the NPC to create the potions will be added if there are enough requests for that feature.
Type "Rejuvenation" with a capital R for the food name to use Rejuvenation potions
Alternatively, select the new Use Rejuvenation Potions checkbox
