<DIV><FONT size=2>Clinical testing would be performed along the lines of
pharmacological classification and hence the type of formulation tested is not
the main criteria. Therefore you would be hard-pressed to find specific info on
herbal teas. I would suggest locating info on the testing of pharmacological
action of any herbal tea that is to be tested.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>1. An excellent although old source for clinical
guidelines for herbal medicines would be a publication of WHO titled:
</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Research Guidelines for Evaluating the Safety and Efficacy of
Herbal Medicines</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>2. Latest and current information on clinical protocols have
been provided in three chapters of the book "GMP for
Botanicals":</FONT></DIV>

<DIV><FONT size=2>b. Clinical trials of herbal medicine</FONT></DIV>

<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>3. In-depth and detailed guidelines have been provided in

<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>a. Pharmacological screening of herbal drugs (includes 22

<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Actually, there is very little information on clinical
evaluation procedures specifically for herbal medicines available in any other
book. Maybe this could be an opportunity for a noteworthy trade or scientific
organization to come up and develop just such guidelines to help herbal
manufacturers better cope with the contemporary regulatory requirements of
herbal products as "Medicines" rather than as "food supplements".</FONT></DIV>
