There is no scientific basis for the claim that the placenta is a great tonic. The placenta is the organ that grows out of the uterus during the growth process of the fetus, where the fetus absorbs nutrients and excretes metabolites. The placenta is expelled after childbirth. The composition of the placenta is protein, calcium, vitamins, etc., there is nothing special in terms of nutrition, the placenta is a great tonic for this statement does not have a scientific basis, eating the placenta does not have a special role. Placenta belongs to the waste in the medical process, it is easy to be infected with germs in the process of disposal, and if it is sold by private individuals, its safety cannot be guaranteed. The placenta itself may carry harmful microorganisms such as measles virus, herpes virus, etc. Consumption of placenta may lead to infections and diseases. If you need to take nutritional supplements, you can listen to the advice of professional doctors and choose scientific and reasonable methods of supplementation, avoiding biased beliefs.
