The cold pathogenic factor is considered a yin evil qi. Its nature is to slow movement down, causing tightness, contraction, stagnation, and impaired circulation. When it is an external pathogenic factor, cold can attack the skin, muscles, and lungs. When it is an internal pathogenic factor, cold can cause an impairment in the normal functions of the spleen, stomach, and kidneys.
Syndromes of Cold
Wind Cold: In combination with the pathogenic factor of wind, cold attacks the exterior of the body and the lungs, causing chills, lack of sweating, occipital headache (pain at the base of the skull), upper body aches, tight shoulders and neck, and a congested nose. The influence of wind causes the symptoms to appear suddenly and affect the upper body, while cold causes the muscles to contract, causing the stiffness and pain. Nasal secretions are clear -- another sign of cold. The treatment principle is to repel the wind and disperse the cold with warm diaphoretic herbs, acupuncture, and moxibustion.
Obstruction Due to Cold: Traditionally known as cold bi (blockage) pain, this condition typically takes the form of body aches or joint pain that is relieved by warmth. The most common Western diagnosis for this pattern is arthritis. Since the syndrome is caused by cold, the joint may actually feel cold to the touch, and the pain typically gets worse in cold weather. The Chinese treatment principle is to increase circulation and warm the acupuncture meridians through which qi and blood circulate by means of moxibustion, acupuncture, and herbs.
Cold Attacking the Spleen and Stomach: In this externally caused disorder, cold causes digestive symptoms such as abdominal pain, clear vomit, and watery diarrhea. Although it usually accompanies an externally contracted cold or stomach bacteria or virus (what we commonly refer to as stomach "flu"), this syndrome can also be caused by eating cold foods such as ice cream.
Cold Congealing the Liver Meridian: The liver meridian passes through the genital area, and this condition is a manifestation of cold in that meridian. Symptoms include testicular pain or shrinking and hernia pain. Moxibustion, acupuncture, and herbs can effectively correct this imbalance in a short time.
Spleen Yang Deficiency: If a person has an underlying deficiency of spleen yang (deficiency in energy and heat needed in order to digest food), cold can severely impair digestive function. Symptoms of spleen yang deficiency include watery stools with undigested food, cold extremities, edema, and a slow pulse. When a person with this underlying deficiency is also affected by external cold pathogens, the imbalance is especially difficult to eliminate.
Treatment first expels the cold pathogenic factor. Then it tonifies the yang aspect of the spleen and kidneys to bring about a long-term increase in the body's basic metabolism, or its ability to maintain the heat needed for proper digestion, which is known in traditional Chinese medicine as life-gate (metabolic) fire. Spleen yang deficiency is treated with moxibustion and warming herbs that tonify spleen yang.
Kidney Yang Deficiency: Since the kidneys are the source of yang metabolic fire for the entire body, a deficiency in kidney yang can make the individual especially prone to cold. The symptoms of kidney yang deficiency include an inability to stay warm, cold extremities, low sex drive, frequent urination, edema (fluid retention), and pain in the low back. The yang deficiency can be corrected with long-term application of moxibustion and consumption of herbs that tonify kidney yang, thereby increasing metabolic fire.
