The Six Stages of disease was first developed by the great master of Chinese Herbology, Zhang Zhong Jing (142-220 ACE) when he wrote the Shang Han Lun on Cold Damage. In the Shang Han Lun, the progression of diseases is examined with all of its diverse manifestations and possible courses. As a disease invades in the Tai Yang, if not properly treated or if there is a deeper susceptibility, the disease can progress into the Yang Ming or the Shao Yang laver. The three Yang layers are characterized as still exhibiting signs of an excess pattern. If a deficiency exists, the disease can progress into the Tai Yin and from there the Shao Yin or the Jue Yin, again depending on deeper states of susceptibility. The study of the Shang Han Lun is critically important in today’s world with an exponentially increasing number of animals who exhibit chronic disease.
In the last few decades, the overall quality of health in all our animal patients has been deteriorating. There is an increase in several chronic diseases including diseases indicative of chronic immune mediated inflammatory diseases like recurrent uveitis, and diseases indicative of significant failure of normal function. In horses one such example is the complex of diseases known as Metabolic Syndrome. This syndrome describes horses with both a metabolic and a hormonal disorder characterized by obesity, regional adiposity, insulin resistance, and laminitis. It is found that these diseases have progressed to the level of the Jue Yin. A Jue Yin disease reflects the separation of Yin and Yang and the collapse of Zheng Qi.
The lectures will cover all Six Stages, starting with the progression into the Tai Yang layer continuing into the Jue Yin layer. Herbal strategies will be discussed as a means of reversing the disease progression in order to return to a state of health.
