Black-Blooded Oracle question

[Samurai]

Hi all. I'm considering playing a Black-blooded Oracle, and I wanted to clarify something. This Archetype is described on Inner Sea Magic pg 32, where it says "[the Oracle's] wounds are infected by her own magic and difficult to heal", but it doesn't give any penalties to Heal checks or anything else. I does say later on that positive and negative energies are reversed for the Oracle, such that Cures hurt and Inflicts heal. Is that what was meant, or is there also some other penalties to healing that aren't listed?

Mechanically, the only healing restrictions appear to be the reversal of positive and negative energy. Assuming you plan to become undead - because, going undead with a Cha caster is made of win - the only issues you'll have are the -4 to Dex-based skill checks. That's not too much of a loss for most oracles, but the benefits of this curse - namely cold resistance - is pretty unimpressive too.
