I just read the other page about nanotechnology processing. They are
using it with Chinese herbal medicine to increase the effectiveness,
and even to produce new medicinal effects from herbs by reducing
particle size the the nano level. This kind of medicine could then be
formulated into injections, tablet form, etc.

Navigating to the page on types of nano teas, they look like instant
tea packets And that's exactly what they are. There's oolong tea,
white tea, yellow tea, red tea, green tea, black tea, puer tea, etc.
Basically, it's all instant tea that's readily dissolvable in either
cold or hot water.

I tried to navigate to the page where it says how small the particles
are, but that didn't open.

But instant tea packets were around long before nanotechnology. So I
don't know what this tea has to do with that. It could be just some
kind of marketing gimmick. Whatever the case, I don't think nanotech
should be used in food.
