Outline
The popularity of eating placenta and placenta therapy, which is also called “fresh cell therapy”, has been accompanied by controversy. The controversy is focused on the scientific and historical evidences. Looking into the scientific research to date, no rigorous evidence for therapeutic effects or hazard was found; the placenta therapy has nothing to do with stem cell therapy; and the “fresh cell therapy” was not supported by Chinese or Swiss government. The history of burying placenta was longer than eating, furthermore, the objection to medicinal placenta has been in existence since ancient times, therefore, long history cannot be used as an evidence for efficacy. Chinese historical regimen, the large demand and profits of health-care products along with the cognitive space given by the absence of scientific research give rise to the popularity of this kind of product under the situation of the absence of scientific and historical evidence.
