Dark rings under the eyes
Published on Skin, Urinary system.
Permanent dark rings under the eyes indicate tiredness in the kidneys. They may also be the product of a heavy night out. In this case, they do not represent a symptom, merely a direct cause-effect relationship.
Frequent dark rings in the inner corner of the eye, near the nose, denote intense activity of the suprarenal glands.
