Effects that duplicate Cure and Inflict spells

[Dread Knight]

Reading the Pallid Crystal from Inner Sea Gods says that it doesn't effect other uses of positive and negative energy only cure and inflict spells and effects that duplicate them; what counts as effects that duplicate them? Would it effect Channel Energy, or a spell like Chill Touch, etc?

[shiiktan]

Presumably wishes or any other spell that can "duplicate" a lower level spell are what counts.

Additionally any effect whose description says "this functions as cure/inflict" if there are any.

[Starglim]

A spell-like ability of, say, mass inflict light wounds would qualify. The witch's healing hex probably does. Channel energy or an undead's touch don't duplicate cure or inflict spells.

edit: Neither a casting nor a spell-like ability of chill touch duplicates an inflict spell.
