Ah Seah, here is the blog u r waiting for, the story goes, was at Changi Airport on Sunday to send someone of to the United States for further studies, was there early so popped over to Cheers to get some drinks......I got a can of traditional remedy concocted into a drink here it is

the traditional remedy Pi Pa Kao made into can drink.
My dear friend saw it and call it

mopiko an ointment for itch...... and there I was still agreeing that it is mopiko, then later corrected the name and the whole evening was surrounded with the issues of "mopiko" and "pi pa ko"! To say both has the same effect for itch one for the skin and the other is for the throat...... The next time I will ask for a can of mopiko from the cashier instead......cheers Ah Seah
