mimimo: the HZS right, different medical halls sell different brands, different sizes.
ZTP have cheaper ones at $20+, but its smaller bottles, means u got to eat more, need 1-2 bottles which is the same as fu hua
and some HZS contents are different, maybe more zhen zhu fen or something, i ever compare before.
but definitely i wont be buying EYS one, its sooooo exp and so small bottle.
i think fu hua not bad, but its exp..
so maybe u can keep that for really more serious period, can opt for ba bao san for the normal not so serious cough, then if really alot of phlegm then go for HZS.
this is what i do la...
ba bao san, start as soon i heard the cough coming. but that is only cough, if package with flu then i will give the western medicine, if finish and still buay sai, i opt for HZS.
usually works, but sometimes i get pissed with the western medicine, so i skip it and go straight to HZS.
it depends on my side, i see the conditions first
