Definition of Eastern Medical terms and theories
Meridians
Meridians, called ‘JingLuo’ (經絡) in Chinese, is an ancient mapping of
the human body in which the Qi flows from the inner most layers of the
organs to the outer dermis layers. There are 12 main meridians that run
from the tip of the toes and fingers upwards as well as meridians that
run from the head down to the extremities. Besides the main meridians,
there are special meridians that run along the muscles, specific
organs, as well as the specific area of the body. Along these
meridians, specific points have been identified to affect the course of
the meridian differently. For example, some points can clear heat from
the meridians, while some can increase blood and Qi flow to the
meridians. Meridians are the basic building blocks for Oriental
Medicine.
The Five Element Theory
The five element theory called ‘Wu Xing’ (五行) in Chinese, is a way to
categorize the Universe as well as the human body (the human body can
be considered a microsystem of the Universe). The five elements are
Wood, Fire, Earth, Metal and Water. In medicine, these five elements
represent different organs and meridians. The interaction between the
elements is applicable to the human physiology. For example, wood
generates fire and fire generates earth. Wood represents the Liver and
Fire represents the Heart. In pathology, if the Liver Qi is not flowing
regularly due to stress or any kind of imbalance, in the long run, it
may affect the Heart, which may show signs and symptoms as palpitations
or insomnia. The Five Element theory is used in Traditional Oriental
Medicine to understand the physiology and pathology, as well as to
determine the treatment modality. For example, there is a Fire
acupuncture point of the Liver meridian to spread the stagnant Liver
Qi. The Four needle technique is rooted in the Five Element theory,
selecting 4 points, 2 to sedate and 2 to tonify the affected meridian.
Yin and Yang Theory
The fundamental theory behind Eastern Medicine and Eastern philosophies
is the Yin and Yang theory. The four aspects of Yin and Yang describe
the relationship and interactions between Yin and Yang. They are
opposition, interdependence, mutual consumption, and
inter-transformation.
Meridians and Qi
Fourteen major channels called “meridians” course through the human
body. A subtle energy called Qi (pronounced ‘chi’) circulates via the
meridians to all parts of the body, even the most remote cells. Qi is a
vital force, the presence of which separates the living from the dead.
Its balanced flow is crucial in maintaining good health. Any
misdirection, blockage, or other condition diverting the amount of flow
or balance of Qi may result in pain, dysfunction, or illness.
