They're selling Traditional Chinese Medicine courses that can be completed in 40 hours and claiming that practitioners will be able to assess and give lifestyle and dietary advice based on this course. TCM is an incredibly complex system in which genuine practitioners can pick apart similar symptoms to make an accurate diagnosis. The same symptom, eg sweating, can be caused by completely different patterns and if an uneducated practitioner gives the wrong advice the symptoms will get worse. I doubt they're teaching anything dangerous but shoddy courses (and those who are arrogant or foolish enough to believe they can master an entire system of medicine in 40 hours) destroy the reputation of a very serious, prestigious and effective mode a treatment and jeopardise the future of a much needed ancient knowledge.
