The black dots that appear in chapter 543, I don't understand the meaning of those. But I don't think they have anything to do with the Shin'eiyaku-pills.

Regarding the poison-part, I think it was only a warning to Haschwalth that getting involved in a fight with one of his own, would only be negative for him personally. Maybe because he's the advisor of the Emperor and Sternritter Grandmaster. He seem to hold a higher, more important position than the others, where negative actions would be worse for him than if any other Sternritter did the same thing.
