Evidence Based Medicine was formalized in the 1990s, largely by Canadian physician David Sackett. Sackett described the goal of EBM is to replace hunches and habits with data and clinical trials. Clinical guidelines were developed involving protocols that tell doctors which drug to prescribe first, what dose to use, when to escalate treatment, and when to refer a patient to a specialist.
Anyone looking for advice on wellness and longevity confronts a tsunami of books, newspaper articles, podcasts, newsletters, and videos from an enormous range of sources: scientific experts, medical practitioners, health systems, journalists, patients, influencers, gurus, quacks. Traditional media offer loads of good advice, often in responsibly edited and well-sourced sections dedicated to "wellness." But the sheer amount of it can be difficult to keep up with, and sometimes the guidance can be downright contradictory.
However, it is regrettable that an organisation such as the World Health Organization appears willing to promote the incorporation of traditional and other medicines into mainstream practice by leaning heavily on emotive language heritage, tradition, and the sharing of local resources rather than on clinical evidence. Then it appears to contradict itself by saying that it doesn't support it if there isn't robust and reliable evidence.
