My sources are probably not as current as Sheila's, however..
John Lust, ND, D.B.M. in "The Herb Book" 1987 states that Black Cohosh is in
addition to being an emmenogogue and antispasmodic, "a cardiac stimulant" and
"large doses can cause symptoms of poisoning. "
If Sheila or anyone else has more current references showing that this herb is
safe I would love to know what they are so I can read them. Please E-mail
privately if more appropriate.
