Usually for me, I will first suspect UTI. There is actually a very cheap way to cure in TCM way, cooking chinese barley. I will usually cook chinese barley with the following: chi xiao dou, bian dou, deng xin, mai tong and "cooked" barley. This is a cooling tea as well. The purpose of this tea is to let us pass urine out more, reason to wash the urinary tract. I must say, it is effective, cheap and nice to drink. There is usually no problem to get my kids to drink. Just a small note, kids who are G6PD can’t drink this tea, due to the bian dou. So must remember NOT to add this herb in if really want to drink.
