Bhikha and Abdul Haq in “Tibb – Traditional Roots of Medicine in Modern Routes to Health” state, “Tibb could be defined as: “The art of serving, with respect, the physis of each person you meet”.” And, “…the complex inter-connectedness of ever-changing and mutually influencing parts requires something more sophisticated than balance. We prefer to describe homeostasis as ‘dynamic optimum functioning’. It is the active component of an ideal state. Dynamic optimum functioning does not always require equal measures of all contributing factors to health. Different personalities require different measures of different contributing factors. Some personalities need creative stress, others need more sleep and some people depend more on certain nutrients than others.”
