Capricorns rule the bones, teeth, and joints, and are therefore prone to breaks and fractures. Taurus is in charge of all things pertaining to the throat and ears making them vulnerable to thyroid issues, weight gain, ear infections, and sore throats. Virgo rules the digestive system and is “predisposed to food allergies, eating disorders, ulcers, and IBS," says astrologer Suzanne Gerber.
