A potion of extra healing will heal you.

Effects

A blessed one heals 8d8 HP when quaffed, an uncursed one 6d8 HP, and a cursed one 4d8 HP. If this would bring your HP above its maximum, your maximum will increase by 2 for an uncursed potion, or 5 for a blessed potion. The potion will also cure hallucination and blindness, exercise constitution and strength, and, if noncursed, cure sickness.

Inhaling vapors (of potion of any beatitude) will heal you 2 HP, up to your maxHP, and exercise constitution. If you're polymorphed, health of your base form is adjusted as well.

Monster use

The potion of extra healing can be generated as a defensive item. Therefore it will be seen in the starting inventories of many monsters, who know very well how to use it.

Alchemy

You can alchemize potions of extra healing with gain level or gain energy to get a full healing. Conversely, one can make potions of extra healing by dipping a potion of healing in a potion of gain energy, gain level, or speed.

Esoteric uses

Dipping a poisoned weapon into a potion of extra healing will remove the poison and use up the potion.

Strategy

Some players, especially pacifists or protection runners, might quaff this potion right away for the maximum HP boost. For players who don't immediately need the HP boost, it is better for them to wait until they can alchemize it to full healing. Even those who don't have the time or ability to alchemize the potion should try to bless it first, since it gives over twice as much maximum HP that way.

The potion of extra healing is decent as an emergency item, but again, the potion of full healing is preferable for this task. Not only does it heal many more HP, but even used when low on HP it is quite likely to still give extra max HP, unlike the potion of extra healing.

If using extra healing potions when hurt, whenever possible be sure that you will heal past full, so the maximum HP boost is not wasted.

Uncursed	6-48 HP	27 HP	5.612 HP	19.8079414 HP	13.9445238 HP	9.65762924 HP

In practice, this means that for a Blessed Potion of Extra Healing, you are likely to heal at least 27 HP (19 HP for Uncursed), and virtually guaranteed to heal at least 15 HP (9 HP for Uncursed).
