talkative,
per my doctor said, there is no method unless he/she 嘔左d痰出黎. We can do is to 拍鬆d痰,let it out.
BTW, when Oscar was sick, I boiled
海底椰(乾)+川貝+苦雨零芝+瘦肉 比佢as water to drink.
you can also add 鱷魚肉. It is soup, not chinese medicine, so you can boil it any time.
At last, 有一間幾出名的葯房介紹左隻葯粉for化痰,幾好,Oscar食左一兩次,就好番lu.
