… if drugs were used in labour and/or a caesarean occurred?

It is understood that the placenta acts as a gateway, an interface between mother and baby. Metabolic toxins from the baby are sent back via the placenta to the mother’s liver to be detoxified from her system. This includes drugs or medications; some of which have a very short half-life in the body. A half-life is the time it takes for the plasma concentration of a drug to reach half of its original concentration. In other words, the half-life of a drug is how long it takes for half of it to be eliminated from the bloodstream. 

I have encapsulated placentas from women who have had inductions, epidurals, spinals, pethidine, syntocinon in labour, and/or for the third stage of labour, elective and emergency caesareans. These women also benefit like those who have had natural, drug-free births.
