Health line originates under the little finger and goes across the palm towards the bottom of the thumb. According to the science of Palmistry, the health line represents the health of a person. Health line is directly associated with health of a person. Interestingly, there is no fixed place of its source. This line can commence from the mount of Mars or from Life Line or from the centre of the palm or from any other place but it should be remembered that this line invariably terminates at the mount of Mercury and thus the line which reaches the mount of Mercury is called the `Health Line`.

As per Palmistry, the health line varies from person to person. In some hands it is very thick while on others it is found to be thinner than hair. This line should be studied with great care. Health, sickness etc. of a person are studied with its help. The health line indicates the health proof of an individual. It has been observed that the health line does not have a specific ending point. The study of the health line reveals the health of a person and any sickness that he or she may have experienced or is likely to undergo. Further, some people may have deep and wide health lines and others may possess lean health lines. The apparent and firm health line is the implication of good health of a person. A broken health line at any point indicates bad-health and moreover, if the health line is broken in many places, it signifies severe and continual illness. It has been said by the practitioners of Palmistry that the absence of health line on the palm is the connotation of an excellent state of health, robust constitution and a strong nervous system.

The practitioners of Palmistry are also of the view that the health line deals with the material well being as well as the physical well being of a person. Health line is responsible in playing a strong part in the development of material wealth also. It has also been said in palmistry that the straighter the health line is, the better the health remains. The twisted and uneven health line is a sign of liver complains. Heavily marked health line that joins the line of heart and head and not found elsewhere is the sign of mental disturbance. According to Palmistry, health line can be the signal of a strong business sense as well as the strength to work hard and to make money when it is found as an undisturbed line. Further, palmistry suggests that depending on the shape and the deepness of the health line, the insight of the health problem varies, like, wavy health line defines potential health problems as a result of anxiety and nervousness and a broken line, tends to show poor health that will create problem in business. When it rises from the line of heart at the mount of Mercury and runs into or through the line of life, it predicts some weakness of the heart.

In Palmistry the pale colour and broad health line are the connotation of bad circulation. It indicates of heart trouble if the line is red in colour, particularly when it leaves the line of heart, with small, flat nails. The different forms, marks and colour of this health line define various aspects of health. In this respect, Palmistry says that, the long and almond-shaped nails indicate a danger of weakness and delicacy of the lungs; the same shape of nails and islands in the upper part of the health line is indicates respiratory problems and tuberculosis. On the other hand, the flat nails especially shell-shaped nails with deeply marked health line are the indication of paralysis and the worst forms of nerve diseases in accordance with the science of Palmistry. Rheumatic fever or Aamavata Jwara is indicated if the health line is very red in small spots. Moreover, the person will probably undergo biliousness and liver complaints when his health line is twisted, uneven and yellowish. When the health line is found deeply marked, and is joining the Head Line and Heart line, it predicts brain-fever. The formation of the line in straight pieces denotes bad digestion and an extra line that branches out onto the life line, defines some sort of life-threatening situation in old age.

In Palmistry, the entire study of health line considers the reading and indications of other lines also like when the life line looks very chained and weak, the Health Line on a hand will naturally increase the danger of delicate health; and when found with a Line of Head full of little islands, or like a chain it clearly foreshadows brain disease, severe headaches, etc. The line is studied with great care and several other lines are deeply studied to get accuracy in the study.
