Externally, Gemini rules the shoulders and upper arms. Internally, Gemini rules the breathing process, nerve fibers, thymus gland, lungs, trachea and bronchi, along with structural features of the clavicle, scapula and humerus. Those who fall under the jurisdiction of Gemini can often be identified by their graceful arms and beautifully-shaped hands. These are dexterous and well-coordinated individuals who often excel at sports and dancing. Gemini subjects may be inclined to suffer from two diseases at the same time, often experiencing nervousness, negativity, passivity or even restlessness. Upper respiratory problems are common Gemini complaints...hay fever and asthma, for example...as are tuberculosis and anaemia. There is also a tendency to suffer from stiff shoulders and injuries of the arms and fingers. Gemini natives often experience pain in the extremities (since this sign governs the arms, hands and fingers) and frequently find their sense of hearing to be particularly vulnerable. Often described as "perennial teenagers," Gemini subjects tend to look younger than they really are. Normally, those governed by this Zodiac Sign have alert eyes brimming with humor, a thin nose (often upturned like that of a child), a long neck and a light gait. As a general rule, they are adept with mechanical devices, working with jewellery, arts and crafts, or doing repair work. Other talents include design, artwork and grapics, interior decoration, magic, illusion and music. By tradition, Gemini is considered a barren sign.

Since this sign also has jurisdiction over the nerves, Gemini natives are often excitable and highly-strung. This association is compounded by Mercury (the planet ruling Gemini), which has always been associated with respiration, the brain and the entire nervous system as a whole. This planet also governs the delicate links between the mind and the different areas of the body. Thus, the Gemini state of mind invariably has a great deal to do with the state of health. Anxiety and nervousness can literally make a Gemini individual physically ill. Relaxation is all-important to this Sign...virtually essential for the general well-being. Because Gemini natives expend so much nervous energy, they would be well-advised to take time to unwind and soothe the jangled nerves. Unfortunately, this is no easy task for a Gemini subject who loathes inactivity. Coffee and stimulants only tend to aggravate matters and should be avoided. Herbal teas, however, do have a calming effect on the Gemini character. Inclined to "eat on the run," Gemini individuals are notorious "junk food" addicts. In order to maintain energy and high spirits, it is important for these individuals to establish a proper diet. Many Gemini natives cannot tolerate large amounts of food at one sitting...three or four smaller meals per day is usually more beneficial to the overall health of those who fall under the influence of this Zodiac Sign. Since the nerves of Gemini natives are far from strong, they usually benefit from relatively tranquil surroundings...a location from which they can "sally forth" on the adventurous journeys which this Sign craves. Exercise should become a daily routine, helping keep the Gemini subject supple, and exercise during the younger years can help prevent the onset of rheumatoid complaints which will often surface later in life.

The Gemini cell salt is potassium chloride, which builds fibrin in the blood, organs and tissues of the body. A deficiency of this mineral can lead to blood clots and circulatory problems. Potassium chloride also keeps the lungs and bronchial tubes clear. Foods high in this mineral are asparagus, green beans, tomatoes, celery, carrots, spinach, oranges, peaches, plums, apricots and wild rice. Foods which aid in a healthy nervous system for Gemini include grapefruit, almonds, broiled fish, shellfish, grape juice, apples and raisins. Consumption of lettuce and cauliflower will also help to combat bronchitis, to which those born under this Sign are particularly susceptible. Gemini individuals also require calcium in order to keep their bones in good condition. Milk, buttermilk and cottage cheese would be excellent choices in this regard.

Gemini natives are happiest when living in forested areas...meadowlands near woods, for example. However, since all true Gemini individuals possess a dual nature, perhaps the greatest contentment would come from living in the country for several months of the year, alternating with a few months spent living in the city.
