Mercury line in palmistry

The mercury line, sometimes called a health line in older books, is a vertical crease that may rise toward the little finger mount. Many palms show it faintly or not at all. Absence is ordinary.

How to notice it

Look from mid-palm or the life line area toward the Mercury mount under the little finger. The crease can be broken, chained, or short. Soft side light helps.

Modern symbolic themes

Contemporary readers often link a clear mercury line with communication style, quick thinking, or how someone shares ideas. Keep that as metaphor for expression, never as a diagnosis.
