The Taurus and Virgo compatibility is so strong. The sixth sign of the zodiac, Virgo, naturally rules the sixth house of health, pharmaceuticals, ailments, daily responsibilities, commitments, rituals, employment, and supplements. Virgo is ruled by Mercury. Virgo is an earth sign with a sad temperament and a variable mode. This causes Virgo to be constantly exhausted, full of self-doubt, and prone to overthinking.
