Healing Elixirs

Healing Elixirs are miraculous items that have been researched incessantly to the point that the methods to produce them are so well understood that they can be made comparatively cheaply.

Healing elixirs work when poured into open wounds but they are more effective when drank. They work quickly from the inside out and restore direct damage to the body such as blood-loss and tissue damage. Notably they do this by massively accellerating the body's own processes, meaning that wounds healed by use of healing potions scar up and do not necessarily return to peak performance. Missing limbs are not restored.
Notable the process of regeneration is quite painful, a burning sensation spreading from the inside out before fading.

These elixirs are divided into two types; minor and major.
Minor Healing Elixirs
Minor Elixirs will suffice to immediately close most minor wounds such as a stab-wound or a minor slashing wound. They will also benefit major wounds but may not be enough to 'fix' them entirely. Most wounds can be taken care of with a minor healing elixir and a bandage.
Major Healing Elixits
Major Elixirs heal even grave wounds. A severed arm can be turned into a scarred-up stump within just a minute or so, a nicked artery seals, Bones fuse. Mortal injuries become survivable or disappear entirely.

However if the wounds are very severe, multiple major elixirs may be needed and even then the body might not be able to repair the damage despite the potions. Things like full-body burns, heavy organ damage or traumatic brain injuries may be lethal no matter how many elixirs one has on hand.
Healing Elixirs often need to still be applied by trained professionals. They may be able to repair tissue damage caused by poisons and diseases but never actually interact with the poisons and diseases beyond that. Some diseases like cancer are actively made worse by healing potions, and things like broken bones will heal wrong if they are not first set properly.
Additionally, excessive use of healing potions also has severe side-effects.

God's Blood:
God's Blood is a special healing elixir that is either granted or forcibly taken from a Divine spirit. A facsimilitude of the true product is also produced by alchemists by using Dragon blood, alongside other rare ingredients.
God's Blood heals all wounds and cures all known diseases, including regrowing lost limbs and curing many birth-defects. It is extremely coveted and costly as a result.

The Methods of creating all healing Elixirs are closely regulated and the sale of elixirs is illegal by anybody not government approved. The risk of tainted produce and the loss of profit by the approved guilds are both large reasons.

Appearance:

Healing Elixirs are mostly of a red liquid, as blood is one of the main ingredients of the potion.
