Yes.

• Creatures with the Recuperation ability remove afflictions from themselves over time (examples: Unicorn Riders, Pangaean Minotaurs, Ancient Kraken, Red Bull).
• Immortal Units repair battle afflictions, but only in their home dominions (examples: Vampire Counts, Master Liches, Wraith Centurions)
• Creatures with the Heal command can use it to remove battle afflictions from units and commanders in the same province as themselves (example: Mother of Serpents, Fairy Queen, Arcocephelian Priestesses, Tien Chi Immortal).
• The Global Enchantment "Gift of Health" causes all your creatures in your dominion to Recuperate as if they were Pangaeans.
• The Unique Artifact "The Chalice" grants the Heal command to the commander who carries it.

The last bit is incorrect. The Chalice doesn't give the Heal command to its carrier.
