The overground parts of Chrysanthemum Balsamita L., var. tanacetoides Boiss. (Family, Compositce), contain a volatile oil, the odor of which is almost indistinguishable from that of oil of Spearmint. The striking similarity of the two oils, together with the fact that the plants yielding them come from different families, induced us to seek information in the literature concerning the composition of the oil of Chrysanthemum Balsamita L., var. tanacetoides Boiss. as compared to that of Spearmint. Very few references were found reporting on the chemistry of the oil, the ones that are available giving information only on physical constants. A number of references of a botanical nature are recorded and a few of historical interest.
The purpose of this study was to investigate in part the chemistry of the volatile oil, to determine the yields at various seasons of the year, and to study the morphology and histology of the plant. Material employed was obtained from plants collected in Michigan, Wisconsin and Minnesota and cultivated in the Medicinal Plant Garden of the College of Pharmacy, University of Minnesota.
Chrysanthemum Balsamita L., var tunacetoides Boiss. is an herbaceous, woody perennial native to western Asia. It was introduced into Europe and from there found its way to the United States. It is commonly known as Costmary, Old Maid, Sweet Susan, Sweet Mary and Mint Geranium. History reveals that the plant has been used in the treatment of many common ailments. In the British Pharmacopceia of 1788 it was recognized and used as an aperient. Some of its other uses have been as a diuretic, astringent, antiseptic, stomachic and anthelmintic.
