Considering that neither rotten eggs nor monkey kidney pus is injected
into humans, this question is irrelevent.


Since more and more products sold in the U.S. are being
manufactured in China, I would say there is no doubt that they are
also making various medicines both prescription and over-the-counter.
From our more recent experiences in the news, I would say that rotten
eggs or monkey kidney pus each may be a possibility if they are
cheaper than current ingredients and similate them well enough to get
by.
