Rosemary is a powerful herb in witchcraft, often used for protection, purification, and memory enhancement. It is burned as incense to cleanse spaces of negative energy and is commonly included in spellwork for clarity and mental focus. Witches use rosemary in sachets, charms, or baths to promote love, healing, and emotional strength. Placing rosemary under a pillow is said to bring restful sleep and ward off nightmares. It is also associated with remembrance and is used in rituals to honor ancestors or strengthen psychic abilities.
