The Water Element in nature
Water is the most yin of all the Elements. It is everywhere, but has no shape, taking only the form given by containers, river banks and the beds of the oceans. Although it is the softest of substances, it can wear away the hardest rock and move around any obstacle to penetrate beyond. It appears both as a solid and as a gas. Water filters through the earth, enters roots of trees and flows upwards. In response to warmth it turns into a gas and appears in the sky as clouds, ultimately to fall as rain moistening wherever it falls and reappearing in streams, rivers, lakes and oceans.
Floods and drought
Water has the capacity to cause havoc. People who have experienced flooding or powerful waves understand how water can penetrate and sweep away all that lies in its path. After the initial surge, flood water will often become stagnant. Disease and pollution follow, resulting in illness.
At the other extreme a drought can be just as devastating. Climatic changes can leave a degree of dryness that inhibits crops, resulting in famine. Adults and children shrivel up and die of thirst and starvation.
Water within a person
Water makes up 55–60% of an adult’s body weight (
Thibodeau and Patton, 1992, pp. 474–476). Most of this water is enclosed in or surrounds individual cells and the remainder is plasma, that is part of our blood. These fluids have many functions, but most involve movement and flexibility.
A newborn baby, who has emerged from living within water, is roughly 80% water. This percentage declines rapidly in the first year of life and gradually as we age our water content diminishes.
The skin and hair of children and young adults is naturally moist and the joints and bones are resilient and pliant. Injuries heal rapidly. Young people’s minds are also flexible and have the capacity to take in enormous amounts of information. Languages can be learned very rapidly. They can flow and change in whichever way life takes them.
As people age their bodies become dryer, their hair more brittle, their skin withered and their movements less smooth. Their minds lose flexibility. They have difficulty with new information and accepting changes in the world around them. Ageing is partly a drying up process, a sign that the Water Element is weakening and that we are losing our water reserves. In spite of Water’s flexibility, when it is constrained and not moving, toxins develop and function is diminished. The newborn with the maximum amount of clean water has the maximum flexibility and softness; the octogenarian will be fluid deficient, harder and less flexible.
The Water Element in relation to the other Elements
The Water Element interacts with the other Elements through the
sheng and
ke cycles (see
Chapter 2, this volume).
Metal is the mother of Water
On the sheng cycle Metal creates Water by containing it. Water has no shape unless contained by the impermeable rocks in the earth. This means that when treating patients who have obvious Water Element symptoms, such as urinary symptoms, these may have originated in the mother Element, Metal. A practitioner may treat the mother to assist the child.
Water is the mother of Wood
The close relationship between Water and Wood is often stressed in Chinese medicine. Hence practitioners will sometimes have difficulty in deciding whether to focus treatment on the Wood or the Water. Five Element practitioners mainly use colour, sound, odour and emotion to decide. The mother–child law, based on the sheng cycle, stresses that symptoms arising from the Wood Element often indicate a weakness of the mother and that treatment of Water is required.
Water controls Fire
On the ke cycle Water controls Fire. A fire hose illustrates how water can be used to control fire. In general, there are many body–mind functions which involve heat and which can be spoiled by too much fire. The control of inflammation, the drying out of joints and the dampening down of excess emotions are all examples. In these cases, Water will contain, control and regulate the excesses of Fire.
Water is controlled by Earth
In nature it is clear how water is controlled by earth. River banks and dams are obvious ways in which Earth contains or directs the flow of water. Earth controlling Water means that a balanced Earth helps Water to also be balanced. For example, if the Spleen is failing to move fluids these may accumulate and in so doing create a disturbance within the Water Element.
