Dr. Frank, for being such an incredible support during this time, I know is agenda is always fully booked, but he would always have five minutes for me. Prof. Jorge Machado, who helped me all the way through, who always replied to my emails on time and was always there for my questions, that I must say where quite a few. To all my family who accepted all my complaints, my excuses and always gave me support and confidence to keep me going, and especially to my fiancé who sometimes was jealous of my work, but who always accepted my long hours in front of the computer . And finally to my manager and my colleagues who gave me as much support as they could, and allowed me to multitask when working, so I could finish on time. 5 6 INDEX Acknowledgments............................................................................................................. 5 Abstract ...........................................................................................................................11 Resumo ...........................................................................................................................13 Introduction......................................................................................................................15 Objectives........................................................................................................................16 Research Methods...........................................................................................................16 1 The functional diagnostics of TCM ...........................................................................17 1.1 Historical aspects...............................................................................................17 1.2 Diagnosis of four components ...........................................................................17 1.3 TCM as System Biology.....................................................................................23 1.4 Periodicity of homoeostasis ...............................................................................23 1.5 Yin, yang and the phases as binary numbers ....................................................25 1.5.1 Phases are part of a circular process..........................................................26 1.5.2 Phases are regulatory terms – “Harmony” of yin and yang .........................27 1.5.3 Phases are vegetative functional tendencies ..............................................29 1.5.4 Phases manifest in clinical signs (orbs) ......................................................30 1.5.5 Orbs of the phase Earth..............................................................................33 1.5.6 System of 10 orbs/functional circles: transition orbs....................................34 1.5.7 The present system of 12 orbs/functional circles ........................................37 1.5.8 Further guiding criteria: calor/heat and algor/cold .......................................37 1.5.9 Guiding criterion extima/outside or intima/inside .........................................40 1.5.10 Guiding criterion yin and yang ....................................................................41 2.
