Functional Properties of Kidneys

The Yellow Emperor’s Classic of Internal Medicine states: "Kidneys control the storage of essence of whole body, so they are also the root for sealing up substances and storing them." The kidneys possess sealing, receiving and astringent (consolidating) properties. These properties allow them to gather and hold on to substances such as essence. If the essence leaked out freely, there would not be sufficient amounts for all the bodily functions that rely on it. Vital-gate fire (part of inherited or primordial kidney yang) that is kept in the kidneys should also be hidden and not be over exposed. The simultaneous storing of the primordial fire and primordial water (part of primordial or inherited kidney yin) means the kidneys provide a place for the essence (yin) to motivate the power of our human vitality (yang). Only the kidneys' sealing, receiving and astringent properties can prevent them form escaping and extinguishing their existence. Therefore, the kidneys are not suitable to carry out dispersing and expelling functions, or to use any methods to distribute their innate functions.

Clinically, most kidney diseases are due to a deficiency of some sort and present as an asthenia syndrome. Tonification is the usual treatment for these deficient patterns because it tries to replace the missing elements in the body. However this is not absolute, sometimes a excess syndrome can be the cause of a kidney problem. Sthenia syndrome, which is the opposite of asthenia syndrome, occurs when there is a strong body resistance to fight off pathogens. Fever is a common symptom with a sthenia syndrome. In this case, a reducing method is applied to help soothe the over-acting stage of the body. It is not uncommon to have mixed and complex condition too, so remedies for resuming healthy energy and expelling the pathogens are generally used in these instances. It is important to weigh the predominant symptoms carefully when generating a diagnosis and apply the correct treatment method to avoid further deterioration.

Conclusion

Since the kidneys affect so many vital bodily functions, maintaining their health is an essential part of disease prevention in Chinese medicine. Retaining youth and vitality is also closely linked with good kidney functioning. This is why the kidneys' importance in health maintenance cannot be overlooked.
