Problem is there's a medical ninjutsu with Yin right in the name. Then again, this also can't be Yin Release going by the databook's logic. While Genjutsu=Yin and Medical jutsu = Yang is an easy way to categorize these, it's actually not impossible that there are jutsu that are opposite from what you expect e.g. Yin medical jutsu.
