Well, if you read the description for the Fire Keeper Soul in the first game...

''Each Fire Keeper is a corporeal manifestation of her bonfire, and a draw for the humanity which is offered to her. Her soul is gnawed by infinite humanity, and can boost the power of the precious Estus Flask. Reinforced Estus Flasks capture denser Estus, allowing for increased restoration of HP.''

Infinite Humanity.... technically, they have unlimited humanity to use... though, of course, how they are able to convert it into an effigy..
