The orig<strong>in</strong> and pr<strong>in</strong>ciples of traditional Ch<strong>in</strong>ese medic<strong>in</strong>e1. The orig<strong>in</strong> and pr<strong>in</strong>ciples of traditionalCh<strong>in</strong>ese medic<strong>in</strong>e1.1 The development of <strong>Traditional</strong> Ch<strong>in</strong>ese medic<strong>in</strong>e<strong>Traditional</strong> Ch<strong>in</strong>ese medic<strong>in</strong>e has been practiced <strong>in</strong> Ch<strong>in</strong>a <strong>for</strong> over 2,000 years.TCM was developed empirically from cl<strong>in</strong>ical experience, and documented <strong>in</strong>many classical texts (4). Dur<strong>in</strong>g the period of 221–207 BC, literature already<strong>in</strong>cluded comprehensive records from doctors of <strong>in</strong>ternal medic<strong>in</strong>e (Ji Yi) anddoctors of external medic<strong>in</strong>e and traumatology (Yang Yi). The Yellow Emperor’sInternal Classic (Huang Di Nei J<strong>in</strong>g: 475–221 BC) systematically documentedhuman structure, physiology, pathology, diagnosis, treatment and preservation.The Treatise on Cold Diseases and Miscellaneous Disorders (Shang Han Za B<strong>in</strong>g Lun)(196–204 AD) described the therapeutic pr<strong>in</strong>ciples of render<strong>in</strong>g treatmentaccord<strong>in</strong>g to differentiation of syndromes. Thus, the theoretical basis of TCM wasfurther strengthened. The first official TCM school, the Imperial Medical School(Tai Yi Shu), was founded <strong>in</strong> Ch<strong>in</strong>a <strong>in</strong> 624 AD. Over time, various departments ofTCM cl<strong>in</strong>ical practice were developed, namely, <strong>in</strong>ternal medic<strong>in</strong>e (Ti Liao),paediatrics (Shao Xiao), external medic<strong>in</strong>e (Chuang Zhong), ear, eye, stomatology(Er Mu Kou Chi), and physiotherapy (Jiao Fa). Dur<strong>in</strong>g the J<strong>in</strong> and Tang Dynasties(265 – 907 AD), cl<strong>in</strong>ical specialisations were also reflected by the publication ofmonographs <strong>in</strong> gynaecology and obstetrics, paediatrics, external medic<strong>in</strong>e,emergency medic<strong>in</strong>e and traumatology.There is also abundant literature relat<strong>in</strong>g to the general practice of TCM. This<strong>in</strong>cludes Shennong’s Classic of Materia Medica (Shen Nong Ben Cao J<strong>in</strong>g) (220 AD),which was the first book completely devoted to the description of Ch<strong>in</strong>eseMateria Medica. The Newly Revised Materia Medica (X<strong>in</strong> Xiu Ben Cao) was the firstofficial monograph compiled and issued by the government dur<strong>in</strong>g the TangDynasty (659 AD). The Compendium of Materia Medica (Ben Cao Gang Mu) is one ofthe classics compiled <strong>in</strong> the M<strong>in</strong>g Dynasty (1368 – 1644 AD). Over the past 50years, a number of textbooks and monographs on TCM have been compiled andpublished. Higher education on TCM is now available <strong>in</strong> a substantial number ofTCM universities and colleges throughout Ch<strong>in</strong>a, as well as <strong>in</strong> some othercountries, such as Australia. Education and research on TCM <strong>in</strong> these countrieshave been well documented, and to a degree, standardized (5).There is today a sophisticated body of knowledge built over centuries, <strong>in</strong>clud<strong>in</strong>gbasic theory, diagnostic procedures and treatment approaches. TCM iscommonly used <strong>for</strong> chronic diseases, but also <strong>for</strong> some acute conditions. It hasbeen used <strong>in</strong> such areas as <strong>in</strong>ternal medic<strong>in</strong>e, gynaecology, paediatrics,traumatology, external medic<strong>in</strong>e, dermatology, emergency medic<strong>in</strong>e, and eye,ear, nose and throat. Accord<strong>in</strong>g to TCM theory it is used to treat not only thesecondary manifestations (Biao) but also the primary causes (Ben) of variousconditions.3
<strong>Benchmarks</strong> <strong>for</strong> tra<strong>in</strong><strong>in</strong>g <strong>in</strong> traditional Ch<strong>in</strong>ese medic<strong>in</strong>e<strong>Traditional</strong> Ch<strong>in</strong>ese medic<strong>in</strong>e philosophy differs significantly from other healthcaremodalities and this strongly <strong>in</strong>fluences the attitude and approach of TCM <strong>in</strong>health care. <strong>Traditional</strong> Ch<strong>in</strong>ese medic<strong>in</strong>e is guided by a unique theoreticalparadigm with key concepts such as the y<strong>in</strong> and yang theory, 1 the five elementstheory, 2 the qi, blood and body fluids theory, 3 and the differential diagnosis ofsyndromes. <strong>Traditional</strong> Ch<strong>in</strong>ese medic<strong>in</strong>e relies on contemporary diagnosticmethods, such as laboratory tests and diagnostic imag<strong>in</strong>g, as well as ontraditional diagnostic techniques. <strong>Traditional</strong> Ch<strong>in</strong>ese medic<strong>in</strong>e treatment aims topromote and regulate the flow of qi and blood, to regulate the functions of thezang-fu organs 4and to balance y<strong>in</strong> and yang. In order to maximize therapeuticoutcomes, patient management relies on Ch<strong>in</strong>ese Materia Medica and TCM<strong>for</strong>mulae used <strong>in</strong> conjunction with dietary therapy, rehabilitative exercises,supportive measures, and patient education and counsell<strong>in</strong>g and may, whenrequired, refer to other types of health professionals.1.2 Ch<strong>in</strong>ese Materia MedicaThe Yellow Emperor’s Internal Classic (Huang Di Nei J<strong>in</strong>g) (475 – 221 BC) recordeddetails on herbal process<strong>in</strong>g, such as Rhizoma P<strong>in</strong>elliae (Ban Xia) and Cr<strong>in</strong>isCarbonisatus (Xue Yu Tan). Shennong’s Classic of Materia Medica (Shen Nong BenCao J<strong>in</strong>g) (220 AD) was the first book that provided the theoretical framework <strong>for</strong>the practice of TCM while also document<strong>in</strong>g details of process<strong>in</strong>g methods <strong>for</strong>toxic Ch<strong>in</strong>ese Materia Medica and expla<strong>in</strong><strong>in</strong>g the rationale of these methods.Alchemy, which is considered to be the precursor of the development of modernmedic<strong>in</strong>al chemistry, was particularly popular dur<strong>in</strong>g J<strong>in</strong> Dynasty (265 – 420AD). Grandfather Lei’s Discussion of Process<strong>in</strong>g of Materia Medica (Lei Gong Pao ZhiLun) (420 – 479 AD) was the earliest complete treatise on process<strong>in</strong>g techniquessuch as various methods of clean<strong>in</strong>g, cutt<strong>in</strong>g, dry<strong>in</strong>g, stir-bak<strong>in</strong>g, boil<strong>in</strong>g andcalc<strong>in</strong>ation. These methods still guide current practice. The Collection ofCommentaries on the Classic of Materia Medica (Ben Cao J<strong>in</strong>g Ji Zhu) (500 AD)documented properties, sources, harvest<strong>in</strong>g and collection practices, andidentification of Ch<strong>in</strong>ese Materia Medica. In 659 AD, the Government issuedtheir first official text, the Newly Revised Materia Medica (X<strong>in</strong> Xiu Ben Cao).Process<strong>in</strong>g techniques were further systematically compiled and <strong>in</strong>troduced asguidel<strong>in</strong>es <strong>for</strong> herbal process<strong>in</strong>g dur<strong>in</strong>g the Song Dynasty (960 – 1279 AD). TheCompendium of Materia Medica (Ben Cao Gang Mu) is the most recognized relevantclassic text and was compiled <strong>in</strong> the M<strong>in</strong>g Dynasty (1368 – 1644 AD) (6-8).1The theory of y<strong>in</strong> and yang orig<strong>in</strong>ated <strong>in</strong> antiquity <strong>in</strong> Ch<strong>in</strong>a. It is a theory deal<strong>in</strong>g withthe orig<strong>in</strong>s of the universe as well as the motion and variation of all th<strong>in</strong>gs <strong>in</strong> the naturalworld.2The five elements are wood, fire, earth, metal and water. People <strong>in</strong> ancient Ch<strong>in</strong>abelieved that these elements are <strong>in</strong>dispensible to daily life and productive labour and thatthese five elements were key to the normal variations <strong>in</strong> the natural world.3Accord<strong>in</strong>g to classic Ch<strong>in</strong>ese philosophy, qi is the primary state of the universe. Qi,blood and body fluids, the essential substances <strong>for</strong> life activities, flow constantly <strong>in</strong>sidethe body and all orig<strong>in</strong>ate from the viscera.4Zang-fu is a collective term <strong>for</strong> <strong>in</strong>ternal organs which are divided <strong>in</strong>to two majorcategories, namely the five zang-organs - the heart, liver, spleen, lungs and kidneys; andthe six fu-organs - the gallbladder, stomach, small <strong>in</strong>test<strong>in</strong>e, large <strong>in</strong>test<strong>in</strong>e, ur<strong>in</strong>arybladder and sanjiao (the triple energizer).4
