Tete,
Wanna see a TCM physician near our place? He is good, give pills, tablet n syrup... not those 3 bowls boil till 1 bowl type.. I would say the med quite effective... n base on ur condition, he'll tell u wat are the food to avoid. e.g., my sis has a terrible cough some times back... n she was told to avoid prawns, which is quite surprising for us.
If u r interested, ask Muddpie for my HP no.
