In fact as I sated, the extract is not equivalent to the tea. In fact liver damage has been reported with the extract.
I am board certified in integrative medicine, and part of the evidence based group of doctors who use suopplements in clinical practice. We do not recommend over 300mg of the extract a day.
While this is generally presumed to be a low toxicity situation, that is not always the case.
Therefore I have an ethical obligation to clarify the situation.
Since your son has been taking this for some time, and since he has now effectively overdose, in a sense....follow up with his doctor about using this supplement is wise in any case.
Please see this.
