Off topic... hm. So that was it.

"Since we're on the topic of poisons, though, let's also talk about charcoal. Charcoal can also help in several, though again not all, cases of poisoning - at least, ingested ones. Charcoal works by absorbing a poison itself and not allowing the body to absorb it. Though, again, this isn't a one-stop panacea, unfortunately."

Smooth, Maomao.
