Rosemary can be burned like juniper and safe for smoke cleansing. It has been used for centuries as a memory aid, said to help with recollection and remembrance. Because of this, it has found wide use when studying, when trying to do dreamwork, when trying to recall past lives, and more. As it is tied with remembrance, rosemary has also been used to make oneself memorable for first impressions as well as encouraging loyalty and fidelity.
Comfrey is known as the consummate travel protection herb, certainly for physical travel from self to vehicle to luggage abroad (and has been known to protect against theft while traveling)—but when paired with proper complements, like amethyst, it can also protect in the astral. Comfrey with malachite is especially helpful for travelers. Some sources also say that comfrey can be used in smoke cleansing and can also facilitate healing energies and encourage fidelity in parted lovers.
