tiger lily> sorry ah, i actually don't know. honestly, i don't know much abt TCM, just that i've been taking TCM med most of my life. for the an tai med, i don't know but my principle is, even if it comes to common medicine that can be bought from medical halls (eg bazhen), should see the TCM dr 1st, cos not everyone will suit the prescription as is. for example, in my case, when i take bazhen, mine is slightly modified to suit my constitution, with some herbs added and others taken out...
