Hi Ladies,
Actually its not difficult to brew the medicine given by Ban Choon Chan. They sell an electric kettle cum pot that you can use to brew the medicine. And all you need to do is to add water to the medicine and plug in the electricity (say in the morning before you go to work) and it will start brewing throughout the day. But it has an "auto-stopper". So when its time to cut off the electricity, the kettle will stop boiling and after a while when the medicine seems cooler, it will reheat the medicine again. So by the time you go home after work, the medicine is ready for drinking and it will still be warm.
think i saw a similar cooker thingy at OG but not sure is it's the same though or if it costs the same anyway i've got some herbs (to boil) + some liquid medicine to drink as well as tablets for a week works for me
