Rosemary is a wonderful herbal ally during winter time. It’s a warming herb that stimulates blood circulation among other medicinal properties.
Rosemary also helps with focus and mental clarity. As an herb of remembrance, it helps to tap into buried memories (great for past life or ancestral work).
Last but not least, it helps clear negative energy.
From a Runic Healing standpoint and generally speaking, I associate rosemary with the rune Raidho on a physical level, the rune Dagaz on a psychological level and the rune Algiz on a spiritual level.
