Well, school has definitely started. I originally thought I would be able to post at least once a week, but here it is, my third week of classes and I am just now able to find time to sit down and write. Grad school is no joke, I actually have to study this time around. My classes are going well and I am enjoying the subject matter immensely.
I suppose I should let you know the classes I am taking this trimester:
Acupuncture Point Practicum - In this class we learn the location and the names of the acupuncture points on the 12 organ meridians.
Acupuncture Point Theory - This class complements Acu Practicum. In the course we discuss the functions of specific points, the locations, the names, the antiquity points, technique in needling, the indications for the point, and most importantly what the point treats. In my opinion, this is by far the hardest class.
Intro to Biology - Yup, intro to bio, just what it says. Basic, basic, basic bio. snoooooooze
Intro to TCM Theory - This is the most concentrated and heaviest work load. The class meets twice a week for a total of 8 hours (and sometimes more if Caylor keeps us late).
TCM Theory is the class I have been meaning to write about. This is the class where we discuss the foundations of Chinese Medicine. In its most basic form everything in Chinese Medicine can be boiled down to Yin and Yang. That's right, everything in TCM can be put into a relationship that is represented by that favorite black and white symbol of hippies and surfer dudes everywhere. Most of you readers will know a little bit about the yin/yang relationship, but I think a brief review might help others.
Yin --------------Yang
Descending - Ascending
Contraction - Expansion
Cold - Heat
Water - Fire
Night - Day
Rest - Activity
Solid - Gas
Female - Male
Winter - Summer
North - South
Heavy - Light
At a glance yin/yang represents opposites and their relationship to each other. Some things are more yin than others or less yang than others. For example Spring can be considered yang, however it is less yang than Summer. If one tries hard enough they can put all things in the universe into a yin/yang relationship.
When discussing yin/yang we naturally begin to explore the concept of balance. When yin and yang are in balance there is harmony, this is represented by the Tai Ji (black and white yin/yang symbol - roughly translated Tai ji means Great Totality). Another yin/yang concept that is seen in the Tai Ji is the idea that no thing is entirely yin or entirely yang. That is represented by the black and white dots of the Tai Ji. This concept is important because if an object is not completely yin or yang then it has the potential to change into its opposite. This is linked to the concept of "Flux" or constant change. Without the impetus for change there would be no growth, no expansion, no evolution. When discussing pathologies and organ disharmonies this idea is of the utmost importance. When we are healthy there is balance between the yin and yang systems in our bodies. If we are sick our yin and yang are out of balance, one may be deficient or the other may be in excess. However, since nothing is truly yin or truly yang it has the potential to correct and balance itself out again.
Am I losing you yet?
Lets look at some yin/yang relationships as it relates to the body:
Yin-------------------------------------Yang
Structure/Bones - Energy (Qi/Chi)
Solid Organs - Hollow Organs (for transporting blood, food, waste)
Corporeal Soul (physical body) - Shen (Mind/Spirit) Ethereal Soul
Body below the waist - Body above the waist
Internal Organs/ Middle of Body - Skin/Limbs
Anterior - Posterior
Relationships of Yin/Yang are hard to see when looking at a healthy body. But when you introduce pathology into the picture, things start to make a lot more sense. For example a yang condition is fever. Excess yang will present as heat and will rise to the yang part of the body (head), the tongue and complexion will be red, there is often sweating and chills (yin compensation for the excess of yang). There are also things like false heat, which is a deficient yin condition that presents similar to the yang condition above, but that is just confusing and we won't get into that right now.
The last yin/yang relationship I would like to discuss are those factors that disrupt yin/yang harmony in the body. They are the 6 pathogenic factors, better known as the 6 Evils:
Wind: Probably the most evil of the six. Wind will drive the other pathogenic factors into you and usually does not invade the body alone. Wind can quickly go from being an external condition to an internal condition if it is not stopped from penetrating into the internal organs. For example sitting by a drafty window with an exposed neck and shoulders will drive the cold right into you. Your body may present with cold symptoms like the chills and runny, stuffy nose (clear mucous) and if caught soon enough you can sweat the wind cold out of you, if you let it go on it will get deeper into the body and become wind heat, you will present with a fever, soar throat hacking cough with yellow mucous (yellow=heat/yang). Internal manifestations of wind are liked with nervous system pathologies. Any condition with symptoms of twitching, spasms, convulsions, and tics is a condition of wind.
Heat: This can be internal or external. There are many types of heat and the way they manifest depends on the organ they are effecting. External Heat damages the heart and the brain.
Cold: Once again this can be external or internal. External cold can lead to hypothermia and frostbite. If cold arises internally it can cause issues like constipation or poor digestion. It can lead to depression or lack of energy. I like to think of a cold condition as one where the body does not have enough internal fire to properly maintain physiological processes like blood circulation and digestion.
Dampness: If you live in the Great Lake States then you know what external dampness is. It's called July and August. Internal dampness is issues with water regulation and retention in the organ tissues. Its symptoms are related to the spleen and sugar metabolism.
Dryness: I am currently experiencing external and internal dryness. My skin and nails are cracked and dry and I have internal dryness of the lungs resulting in loss of my voice and a slight loss of breath. Dryness can very much result from a dry climate like here in Denver, or it can be due to lack of water intake or water circulation in the body. Dryness hurts the kidneys, as they are responsible for water circulation in the body.
Summer Heat: I don't really get this one yet. I know that it is similar to heat and often combines with dampness. Also it is seasonal and only occurs in the summer, hence the name "Summer Heat".
This is just an introduction to the pathogenic factors. As I begin to discuss organ functions and and disharmonies I will be coming back to these quite often.
Okay, so we have covered a little bit of the basics. Try to digest this theory of yin and yang, it is one of the most beautiful concepts in TCM. There are still two other basic foundations of Chinese medicine that I need to tell you about, but they will have to wait.
