Default Adulterated commercial teas... research report

Fortune on his 1848 trip through China discovered the Chinese were
adding plaster(hydrogen sulfide gypsum) and Prussian blue(cyanide
paint pigment) to make green tea more green and acted like a
preservative. This was made public in 1851 which gave added impetus
for the East India company to develop India as a tea source.
