There are 4 ways besides an Arco Preistess to heal an affliction.

1. Cast the global spell Gift of Health. That spell hels units in your dominion.

2. Summon a Fairy Queen. She gets the Heal ability just like a Priestess.

3. Forge the unique artifact The Chalice. That heals afflictions on units in the same province.

4. There is a T'ien Ch'i hero with the heal ability - her name escapes me at the moment.

Searching for sites is just something you have to bite the bullet and do - although you can suppliment with the site searching spells like Auspex.
