Zodiac: Cancer, Scorpio, Gemini
Bloodstone is one of only two green stones that I recommend for clients with past or current issues related to cancer, or a family history of cancer. (Not intended as a substitute for other treatments, but as a compliment). This is because most green stones promote growth.
Bloodstone is a fantastic cleanser for the blood and lymphatic system.
Please remember that it is crucial when working with your stones to properly 4C (cleanse, clear, charge & correct the D.O.R.) them, yourself, and your space each time before working with them.
