Amethyst has long been called the "sobriety stone." In ancient Rome, crushed amethyst was added to wine cups to prevent drunkenness. It is said to assist with healing alcoholism, compulsive behaviors, and addictions of all kinds. Amethyst brings energies in mystical realms of stability, peace, calm, balance, courage and inner strength. It is often used in metaphysics and crystal healing to protect against psychic attacks.
