"Madam Pomfrey says he’ll have to stay here a week or so... keep taking essence of rue..."
Harry Potter regarding Ron Weasley after he was poisoned[src]

Rue,[1] also known as common rue,[3] is a kind of evergreen shrubs native to the Mediterranean region, Macaronesia and southwest Asia, with a distinctive bitter taste.[4]

Rue has healing properties, and is used in wizarding remedies: essence of rue is used to recover after poisoning,[1] and it is also used in the treatment of mad dog bites[2][5] and Felix Felicis.[3]
