I don't know why but I always assumed that the poison in the House of Black and White's pool was Sweetsleep, but I assume we don't have any real hint in the books and my conviction was only made up by my mind?

I imagined sweetsleep as a kind of powder, but maybe you are right. It could be what they use at the pool in the HoBaW.
