As others have pointed out, inclusion in ICD-11 does not mean placing a seal of approval on anything. Without classifying things it is difficult to analyse them systemtically, and inclusion of aspects of traditional medicine in ICD-11 is designed to facilitate precisely that.
To respond to Maynard Clark's question, there is plenty of WHO-led work being done on traditional medicine in Africa and Asia. In Africa, a major publication on the subject is being prepared by Dr Ossy Kasilo, Regional Advisor, WHO-AFRO, while in Asia work is currently underway under Dr Sungchol Kim at WHO-SEARO to review progress in the last ten years for reporting to the Regional Committee.
