A healthy group is a feast of content adventures in Baldur's Gate 3, but keeping them at 100% is a challenge. A member of your party may have injured themselves while doing a far jump or triggering a trap that caused the injury. Stupid mistakes like this are common, but just because someone is hurt doesn't mean you have to remove the health potions. There are cheaper methods to heal your party members.
The first thing you need to do to heal a member of your party is to check for food in their inventory. Food is an inexpensive way to regain some health, especially at lower levels. You might gain four or six health points after eating an apple, and fully cooked meals are an effective way to gain even more.
If you don't have any food, check to see if everyone is injured. When an entire group isn't at 100% and you can use a break, a short rest is a good idea. You can only do this once a day between long rests, so those are also valuable, but your last and last option should be to use health potions and healing spells.
Most of the healing potions you'll find in Baldur's Gate 3 come from vendors, looting random boxes, old backpacks, corpses, or as rewards for completing tasks for NPCs you encounter. They are instrumental, and you primarily want to reserve them for use during combat. Drinking one costs only as a bonus action, leaving your character able to perform its move and action, perform a spell, or attack. All potions are limited in quantity.
The same goes for healing spells. A caster's healing spell usually costs them a spell slot, which they usually only recover after a long rest. It's a full night's rest, and your party may not be able to return to their camp to rest.
There are a multitude of alternatives to heal your party members. Just because the food doesn't say in the description that it will heal your character doesn't mean it won't. But make sure it's not dangerous. A mushroom you find on the ground by someone who has only lived in the city could turn out to be poisonous. However, a trained ranger or someone with a background nature can easily choose the best berries and wildlife that everyone can safely eat.
