Everything in the universe is the work of yin and yang. Yin over yang, a thing has the nature of yin; yang over yin, a thing has the nature of yang. The neutralization of yin and yang is called [t'ai chi] or [Zhong dao], which is the harmonious truth that people are pursuing. Experts’ studies of things in the universe in the end all prove that everything has yin and yang.

　For example: we have [positive] ions and [negative] ions, [positive] energy and [negative] energy. And in the big universe, even an atom also has the [Proton] with positive charge, the [electron] with negative charge and the [neutron] without charge.

　Ever since ancient times, Chinese Taoist has been pursuing theurgy with Dan. The alchemist would directly calcine the cleaned oyster shells, then levigate it into powder and eat it. In this way, the heavy metals can not be removed and therefore chronic poisoning often counterproductively occurs. But now, with high-tech, high calcium mineral substances (like corals, pearls, shells, oysters, keel, etc.) can go through the following process: pickling (removing turnips), calcinations with high temperature and grinding by gasification (no residual heavy metals).

　Then after adding the ion antagonist and necessary trace elements for the body, we have the so-called ionized calcium powder. In ancient times, monks were called [Budan] because those people, wearing fabric clothing and carrying catholicon, used to bring out without effort panaceas that can save the society, High calcium minerals in medicine classics are regarded as extracorporeal Dan medicine, while pneuma is considered as corporeal Dan medicine. Regarding the universe as a huge furnace and the human body a smaller one, illnesses will be removed while the Dan going with the essence and vital energy, yang over yin and water and fire intersection. From the point of the modern view, [Ca] is a strong alkali and appropriate application of it to the human body can help neutralize acid.

　Among the water that takes up 70% of human body, water in the cells accounts for 50 percent and extracellular water accounts for 20 percent. With the osmotic pressure of water, the alkalinity of [calcium] can quickly balance Imbalance electrolytes in the body will mostly cause serious [acidic body condition]. The theory that all diseases have the same one cause indicates that the only source of diseases is ~ [acid] toxin. So how can there be so-called high blood pressure，diabetes or kidney diseases if the acid toxins are removed?

　But this truth has been exaggerated as one source of cure for all diseases.  How can all diseases be cured by the [alkali] only? This kind of shadow, prompted by the psychology of pursuing mystification, will surely be what professional medical persons sneer at. However, it is definitely a great pity that such fantastic [calcium ion] is degraded to wizardry or necromancy.

　Acidic boy condition is strongly repulsive to alkaline [ion calcium water]. This can be demonstrated by our [five tastes]: people with weak heart will have sour taste; people with weak livers will have bitter taste; and other symptoms are shown in the figure. Daily taste will vary as the body condition changes. When you have returned to normal alkaline body condition, you will have flavourless or slightly sweet taste. It will not take a long time, and mostly 90 days there will be recovery change, depending on how severe the body’s acid condition is.
