Wortcunning is the knowledge of healing and magickal properties of plants combined with the practical skills required to make use of this knowledge. That is, the knowledge of herbal lore and the use of simples as well as the skills for making salves, potions, and other herbal preparations for healing, cosmetic and magickal use as well as the skills and knowledge involved with growing and wild harvesting the necessary herbs. Brewing beer, wine, and spirits can also fall under the skills implied by the term wortcunning.
Wortcunning comes from the old English “wort” which refers to any useful plant and “cunning” meaning practical knowledge or cleverness. It is considered by many witches to be an essential skill.
