Cough?

Brought Renee to the chinese physician yesterday before gg to my mom's and it turned out that her cough was not a 'residue' of the earlier flu she's caught. It was due to her nose sensitivity. I remembered she was diagnosed as having sensitive nose when she was an infant by both the Paediatrician and this physician. She once had this cough when she was younger too.
My hairstylist heard her coughing when she was napping in the salon and though it was a light cough, she felt heartache and told her staff to go to Eu Yan San to buy a box of Hou Ning and asked me to give it to her But she later took it back (she gives her girls this) when I wanted to pay her hahaha. This box cost S$50+(after member's discount), so how can I just take it for free? Not my style... I went to the shop later to check the stuffs out and was sooo confused 'cos there're other cheaper ones that target more specifically the 'problem'. In the end, I decided it would perhaps better to consult the physician for a prescription.
So, luckily for my 'non greediness' and confusion at the shop hee, I've not given her the 'Hou Ning' or "Hou Zao' yet(anyway, I've always believe that it's better to let a physician check you up(more so when u're unsure) and give u a prescription base on your body condition at the moment) - but since quite a few had mentioned that this EYS's product is good, I shall keep it in mind :)
