Two people. One practises Chinese medicine in Chengdu; the other builds the instrument and the climate record behind it. Neither of us is licensed in the United States.
Master’s degree, Chengdu University of Traditional Chinese Medicine. Over thirty years in clinical practice. Named a ming lao zhong yi (名老中医) by the city of Chengdu — a designation given to senior practitioners of Chinese medicine.
He decides what the questionnaire asks and what the seasonal readings say. Where the classical texts and the modern national standard pull in different directions, the call is his.
MBA, Sichuan University. Over twenty years researching hospital management.
He builds the English adaptation of the questionnaire, the climate pipeline behind the city pages, and this site. He is not a clinician and does not decide clinical content.
China’s national standard for constitution classification was written for, and validated on, Chinese populations. Several of its blood-stasis items ask a person to judge their own complexion — a dark face, brown spots, dark circles, lips that look blue or purple.
In a Nashville trial cohort of 191 adults aged 40–85, blood stasis scored 22.6% among the non-obese participants and 11.2% among the obese, set against a 1.4% figure from a separate Chinese study. That comparison runs across two studies, not within one, and the cohort was recruited for colorectal-cancer risk, not from the general population.
Our reading is that the gap is mostly the questions rather than the people: ask a white adult of sixty whether they get brown spots, and you are asking about sun damage. That is a hypothesis, not a finding. This site exists to see whether a version with the appearance-based items replaced behaves any differently.
We would rather be corrected than agreed with, and the people best placed to correct us are practitioners who see these patients every week: [email protected]
We do not treat, diagnose, or see patients in the United States. The assessment is educational, it is free, and nothing you answer leaves your browser.
