After a bit of a search, Poison Jelly should've been ドクゼリー　(Dokuzerii),　ドクジェリー(Dokujerii)　or 毒ゼリー/毒ジェリー. ドクゼリ/毒芹 (Dokuzeri), however, means Cowbane (or poisonous japanese parsley/celery if word for word).

As for Herculean Madness... well, 怪力 can mean insane strength, or Herculean strength, but that is if it is pronounced かいりき (kairiki). In our case, it's part of an actual term, 怪力乱神 Kairyokuranshin. In addition, the translator confused 乱神 (no actual term by itself) with 乱心 (which means madness), which are pronounced the same.

TL;DR
 * It's Cowbane.
 * CR Translator used 怪力(かいりきKairiki)+乱心 instead of 怪力乱神 (Kairyokuranshin).
 * Never trust latest blog section. In fact, how did you forget which chapter we're on?
 * Chaos is genderless.
