Yin and Yang, and Five Element Theory
Yin and Yang, and Five Element theory is the foundation of Eastern philosophy which gave birth to Traditional Asian medicine. Yin and Yang are derived from Tae Geuk, then it goes through separation and unification. From this movement, new characteristics are derived which is called Five Element. Everything in the universe has in it and goes through this movement. Ancient theologists found out these characteristics in the order of nature. If this Five Element movement merges together, it forms the shape, and if this movement separates again, it goes back to its pure Five Element energy. Thus, Five Element has both aspects of incorporeal and corporeal characteristic which is able to apply to the universal order. The Five Element named Wood, Fire, Earth, Metal, Water has the meaning for both this shape and characteristics. And this theory becomes the foundation of Traditional Asian medicine which we can modify and manipulate in the body as a Qi movement when we are treating diseases.

Pulse Diagnosis
Pulse diagnosis is one of the main diagnostic methods used by ancient practitioners. From the pulse diagnosis, practitioners can easily understand the disease’s characteristics and severity better. Thus, it is one of the indispensable diagnostic methods. The heartbeat appears as a wave and this wave has many other meanings but it means meridian in Traditional Asian medicine. And practitioners can understand the status of health of a person by feeling this pulse.
There is five Zhang (Jang) organ system in Traditional Asian medicine. And practitioner can feel these five Zhang organ’s pulse from a certain location of one’s wrist where the radial artery lies. It is called Cun (Chon), Guan (Kwan), Chi (Chuk) position in the wrist. The basics of the pulse can be felt by big or small, the shape of the pulse, height, strong or weak, fast or slow, excess (shi) or deficient (xu).
And there is six Fu (Bu) organ system in Traditional Asian medicine. And the practitioner can feel this six Fu organ’s pulse from a certain location of one’s wrist where the radial artery lies. It is called Cun, Guan, Chi position in the wrist. However, it is slightly different from the five Zhang organ’s pulse position. Since it is the Fu organ’s pulse, it can be felt on the surface aspect of the Cun, Guan, Chi position. And skilled practitioners can feel excess (shi) or deficient (xu), characteristics, strong or weak, the height of the pulse from five Zhang organ system and six Fu organ system, and able to modify it to harmonize Qi and blood.
There are four ways to understand pulse diagnosis. The first one is to check Renying (Yin Young) and Cunkou (Chon Gu) pulse to see if there is Yang excess (shi) or Yin excess (shi). If Renying is stronger than Cunkou, the person has Yang excess, if Cunkou is stronger than Renying, the person has Yin excess. To harmonize Yin and Yang energy, the practitioner can modify the Yin or Yang meridian to either make it float or submerge by acupuncture treatment.
The second one is to check the excess or deficiency of Zhang Fu’s pulse from the Cunkou pulse. The practitioner can understand engendering or controlling of Zhang Fu system by taking this pulse, and able to make the Qi ascend or descend by acupuncture treatment.
The third one is to distinguish the 27 pulses from the Cunkou pulse. By doing that, the practitioner is able to understand the characteristics of the disease and what kind of Six Evils (Six Pernicious Influences) derived the disease, and the practitioner is able to treat with acupuncture.
The last one is to distinguish the Four Body Constitution of the person by taking the Root pulse of the Zhang organ pulse. And the practitioner is able to modify the Qi to ascend, descend, in or out by acupuncture treatment.

Four Constitutions
In Traditional Korean medicine, there is Four Body Constitution analysis when distinguishing the body’s energy type. Dr. Lee Jae Ma from the Chosun dynasty in Korean history established the Four Constitutional system in Traditional Korean medicine. The four different Constitution is formed from the difference between the energetic strength and weakness among the Zhang organs. This difference gives rise to the major four types of Body Constitution and their characteristics. The Four Constitutions are named Tai Yang (Tae Yang), Tai Yin (Tae Eum), Shao Yang (So Yang), and Shao Yin (So Eum). It has a different approach to each type of Constitution with respect to treatment since it has different weaknesses, strengths, suitable food or herbs, character, and mentality. The biggest Root pulse of the Zhang organ’s pulse presents the Constitution of a person.

The Six Evils
The Six Evils or Six Pernicious Influences are described in the Classics of Traditional Asian medicine. The Six Evils are derived from the Five Element which is filling up the universe. When the Five Element movement comes close to the Earth it changes to the Six Pernicious Influences which a person can feel in their body. The Six Evils has the foundation on Wood, Fire, Earth, Metal, and Water but the new Fire appears because the Earth’s axis is tilted 23.5 degrees from the plane of its orbit around the sun. The Six Evils are Wind, Cold, Summer Heat, Dampness, Dryness, and Fire. The season changes are based on this Six Evils movement, and it can affect a person’s body and health which can cause illness or diseases.
