American medical care is very developed, especially its medical education and the level of general doctors are world-class. The opinion of American family doctors is worth paying attention to, which roughly reflects the awareness of hydrogen medicine in the international medical community. The doctor's misconceptions about hydrogen medicine illustrate how little hydrogen medicine is understood in the mainstream medical system. Although Professor Nicolson explained that this is because the hydrogen medical research, especially the clinical research, is mostly conducted in Japan and China, the United States has relatively few hydrogen medical research, and the hydrogen health products in the United States are not very common. Ordinary people, including doctors, have an understanding of this concept. Lower is normal. This shows that in order to make hydrogen medicine play a full role and attract more scholars to participate in the research of this topic, further efforts are still needed to promote it.
