There ARE problems with regulating herbals.  I would never buy herbals
OTC in a supermarket or from a health food store.  Just like I wouldn't
go to a non-qualified health practitioner, I wouldn't dream of trusting
clerks who have little or no training.  I work with a number of
homeopathic/herbal pharmacies where the pharmacists ARE well trained.
They either make their own preparations or sell ones they know are safe.
Another bet would be to work with a certified herbalist.  The HP who
commented that he thinks this is all a fad is dead wrong.  The field is
growing, growing, growing... Even hospitals and health funds are
participating.

BTW, a number of you have written to me with the question about
pregnant/lactating and children fasting on Yom Kippur.  There are no
clear answers because Jews belong to different branches ranging from
the most liberal Reform to Haredi or ultra-Orthodox.  It is generally
accepted that young children and those who have medical conditions
are exempt from fasting.  One thing I've learned from living in Israel -
you ask two Jews, you get 3 opinions...
