Aren't they all from China?. . I haven't drank 'FOO CHA" in many yrs.Asian here with lots of Chinese friends
My friends are split in regards to this. Half swear by Chinese medicine and take it religiously for everything. They think it works and is more gentle than Western medicine.
The other half argue that it's unregulated and produced in China so goodness knows what is in it. Do you really want to drink unregulated substances from China?
When you say floaters, I'm assuming you mean floaters in your vision and not the floaters that won't flush away? lolIt's not a Chinese herb per se but I sometimes get floaters and taking bilberry supplements seems to help with that...
