Hi Scarlet
Sorry to hear you're ill, hopefully you are better by the time you read this.
Listen to PTree, it says right on the tylenol box,"may dammage liver". THERE IS A REASON THAT THEY HAVE TO PUT THIS ON THE BOX. They put the word "may" in there to try to have you believe it is safe. Yeah right.
Also you have been fighting that cold for some time now. You should just concentrate on resting, eating right and staying warm until you beat it. Then go back to your liver.

P.S. Herbs are medicine and like prescription medicine can cause damage. Please be carefull.
