I did Yum Cha with a very wealthy Chinese jw (in HK) who very kindly explained tea in Chinese culture. He said there were approx 300 different teas, all with medicinal properties. As we ate we were continuously given Jasmine tea. Actually you have to tap the top of your teapot when it is empty, as it is too noisey to get the attention of the wait staff! He told me the reason for this particular tea. It aids in digestion but most importantly, assists in getting rid of fats, so if a dish was a little greasy, I drank the tea. Yes it worked very well and very quickly.
