The instructions say to take 2 bottles but I ate one and that's that. The end of the runs. Maybe you can do a few more doses if you got the serious case lol.
It definitely beats that thing called Peptol Bismol (yukity yuks) and I only ended the runs after 3 days of Peptol Bismol but had no other choice because I was in the US back then, and wishing for my Bao Ji Wans. Next time I will remember to bring a couple with me just in case.
10 vials per box, I like the packaging. It's nice and old-school, it's got embossing too. When I was little, I used to keep the plastic vials for no reason.
Li Shiu Kei from Foshan, Guangdong developed them in 1896. He moved to Hong Kong after the Chinese civil war occurred.
Back in 2010, the Po Chai in capsule form were found tainted with cancer-causing chemicals and both products were banned in Singapore, the capsule form is no longer in production since they aren't even popular to being with; I never knew they came in capsules either. The pills are not tainted so the ban on those were lifted shortly. They are available on Amazon if you do not live in Asia.
