As far as I understand, no plants have human hormones in them. However,
another excellent source you might check out is Bastyr College, a college of
natural medicine in Seattle, esp. any practitioners experienced with cancer as
some cancers can be affected hormonally. Therfore these doctors would be
interested in finding hormone affecting phytotherapies.
By the way, it's spelled ginseng, not ginsing or gingsing.
