Q. Does Pycnogenol contain estrogen? I would like to try it for my hot flashes but my doctor said I shouldn't take it if it contained estrogen.
A. There is no estrogen in Pycnogenol. This extract of French maritime pine bark has been shown to relieve hot flashes in one study (Acta Obstetricia et Gynecologica Scandinavica, Aug. 2007). Another study concluded that Pycnogenol does not have estrogenic activity (Journal of Reproductive Medicine, Aug. 2007).
