Ayurveda teaches that face is the mirror of the mind. Disorders and disease is manifested on the face in the form of lines, wrinkles, etc. For example, horizontal wrinkling on the forehead indicates the presence of deep-seated worries and anxieties. A vertical line between the eyebrows on the right side indicates repressed emotions in the liver. On the other hand, the presence of a vertical line between the eyebrows on the left side will indicate that the spleen is holding in emotions.
A full and fluffy lower eyelids is an indication of impaired kidneys. A butterfly-like discoloration on the nose or on the cheeks may signal mal-absorption of iron or the folic acid and the sign of a low agni (fire).
The nose can be used to determine the dosha of a person. Vata persons have crooked nose. Kapha persons have a blunt nose. On the other hand, a sharp nose may denote a person with Pitta dosha.
