the difference used to be that between overhealers (such as scorchstones) and normal ones (like greater healing scroll, short sleeved yellow tunic, eca, ...) - anyway there's no difference between them in the new BD atm (all healers are normal ones, there's no overhealing) which was listed as "known issue" in the beta news before the "war" started, so it may be changed back to the way it was.
for clarity it was like this:
normal healers healed you *before* receiving damage
overhealers healed you *after* receiving damage
you currently have 40/50 HP, get 30 damage that round and use a healer that heals 50 HP
if it's a normal healer you heal up to 50 and then take 30 damage, so you have 20/50 HP afterwards
for a overhealer you first take 30 damage, so you have 10/50 HP now and then get healed up the 50 HP, so you end with 50/50 HP
