We have some splendid verveine soap inspired from The Vampire Diaries!
Verveine is a potent herb, and a vampire’s most well-known weakness. If a vampire makes physical contact with verveine in any form, it will burn them. If a vampire ingests verveine, the vampire’s throat and digestive tract will be burned and they will become feverish and extremely weak. If a human ingests or holds verveine somewhere in or on the body (such as holding it in a hand or pocket, or wearing it in jewellery), the human is protected from vampire compulsion and entitled to free will.
