Question on +hp/sp recovery gears/cards

[Menace651]

Ive never really understood tested these gears/cards. Do gears and cards like Archangeling and Eggyra that add +%hp/sp recovery does apply to consumables as well? For example do you gain more hp from using a potion with these cards/gears equipped or is it just for natutal hp/sp recovery? Also does it work for the "resting skills" for LK/Champs skills Tension Relax, etc.
