"Some love potions use more thorns instead of rose petals, although I personally have found the effects of these potions tend to be brief and somewhat unstable." —Zygmunt Budge[src] Rose thorns are sharp, hard structures found on the stem of a rose. They have magical proprieties and are used as an ingredient for Love Potions, though Zygmunt Budge felt potions made with rose thorns were of brief effect and unstable, and preferred to use rose petals instead.
