Dogwood (Cornus spp.)
Dogwood (Cornus spp.) is a deciduous tree that has showy, four-petal flowers in early spring. The indigenous peoples of the boreal forest in Canada traditionally used Cornus stolonifera for diabetes or its complications. Elders of the Saanich and Cowichan Coast Salish people of the southern Vancouver Island used Cornus nuttallii bark to treat respiratory ailments.
There is limited human evidence about the use of dogwood for use in cancer and as an antioxidant. However, future studies may investigate these areas further. Dogwood has been studied with other herbs to see its effects on hormone levels in postmenopausal and infertile women, although currently, there is a lack of strong evidence for these conditions.

A traditional Chinese combination of herbs seems to have helped a woman with postmenopausal levels of follicle stimulating hormone and luteinizing hormone to become pregnant. Although this result is interesting, further research is needed in this area.
There is currently insufficient available evidence to recommend dogwood for or against the treatment of postmenopausal symptoms. More studies are needed in this area.
