Moonstone is used by healers to stimulate the functioning of the pineal gland and balance internal hormone cycles with nature's rhythms. Moonstone is a stone of inner growth and strength. Though often considered to be a woman's stone, it can be beneficial to men in opening the emotional self. It is said to be helpful for headaches and backaches. In Arab countries women often sew moonstone into their garments, because it's considered a symbol of fertility.
