I love this evergreen herb for a number of reasons, not the least of which is that its also the namesake of one of my grandmothers, which in turn became my middle name.
Rosemary is a powerful cleansing herb that not only removes negative energy or entities, but also fills the energetic void with its own uplifting and powerful high vibration energy. You can plant it around your porch or doors, or make a spray or herb bundle to burn and get the same effect.
Part of its protective and purifying properties are because of its magickal symbolism, linked to Venus, the Virgin Mary, and even Jesus Christ. It also contains a high level of the phenolic compound camphor, which is a strong purifier of spaces and deterrent for all manner of negative energy and spirits.
It is also an astringent herb, and makes a good tea, a toner for your skin, or additive to your cleaning solutions.
Rosemary can aid in psychic development, dreaming, and even in preventing nightmares. Dream pillows made with lavender, mugwort, and rosemary are common for aiding healthy, restorative, and psychic sleep.
