As we are told by most salespesons, the balls work on the meridians much like acupuncture or shiatsu massage. According to Chinese traditional medical theory, these meridians (Jingluo) are channels or pathways through which vital energy (Qi) circulates within the body. Acupuncture points are also distributed along these Jingluo meridians. By means of the Jingluo, the ten fingers are connected with the cranial nerve and vital organs of the human body including heart, liver, spleen, lungs, kidneys, gallbladder, stomach and intestines. By stimulating these points with the Baoding balls, each meridian is stimulated which in turn can create better circulation of vital energy and blood within the body. As one Chinese brochure states: (literally) "It can cause the jingluo unblocked and thorough, the vital energy and blood to function in harmony. the muscles nimble, the bones strong, the mind sober, can invigorate the circulation of blood, and can prevent and cure hypertension and various chronic diseases. If you keep on taking exercise every day for months and years, you can get the fine results of keeping your brain in good health with high intelligence and good memory, relieving your fatigue, drowning your worries, and moreover, prolonging your life." After a week of practice I cannot confirm the above claims, but I did find working with the balls a very rewarding experience.
