Well.....no war lah....just that po chai pills are easily available. N cheap.
Furthermore this is the standard pill i grew up eating whenever i got stomach upset.
The loperamide looks like not readily available.....looks like it is for more serious case of food poisoning.
For Western medicine, the common prescription is eat carbon tabs.
I got stomach flu before.......in the end eat pochai pills to cure.
