Monarda didyma L. - Lamiaceae - scarlet bee balm, Oswego tea, bergamot, Scharlach-Monarde, Scharlach-Indianernessel, Goldmelisse

Perennial herb, up to 1.50m tall, native to eastern Northern America, cultivated as ornamental; leaves ovate-lanceolate, unequally serrate; verticillasters in terminal capitula to 6cm in diam., bracts short petiolate, leaflike, red; flowers scarlet.

„Its odor is considered similar to that of the bergamot orange (the source of bergamot oil used to flavor Earl Grey tea)… Beebalm has a long history of use as a medicinal plant by many Native Americans, including the Blackfeet. The Blackfeet Indians recognized this plant's strong antiseptic action, and used poultices of the plant for skin infections and minor wounds. An herbal tea made from the plant was also used to treat mouth and throat infections caused by dental caries and gingivitis. Beebalm is the natural source of the antiseptic thymol, the primary active ingredient in modern commercial mouthwash formulas. The Winnebago used an herbal tea made from beebalm as a general stimulant. It was also used as a carminative herb by Native Americans to treat excessive flatulence.“

„M.didyma var.80-1A oil was dominated by linalool (55.38%), geraniol (20.71%), and para-myrcene (8.15%). The dominant components of the M. didyma oil were thymol (41.17%), γ-terpinene (15.88%), carvacrol (15.20%), and para-myrcene (12.58%).“

The essential oils of M.didyma obtained by supercritical carbon dioxide extraction contained thymoquinone (36.0%), thymol (16.7%), methyl thymol (7.8%), 1-octen-3-ol (6.5%) , and α-terpinene (3.0%) as main components.

The volatile oil extracted from dry aerial parts of scarlet bee balm with supercritical CO2 gave thymoquinone 0.6mg/g.

Hydrodistillation of thymoquinone from wild bergamot (Monarda didyma) with supercritical CO2 leads to substantial loss of this compound. Extraction with hexane yield thymoquinone (0.7mg/g, extract thymoquinone concentration 2.6%), while supercritical CO2 extraction was 0.6mg/g with high thymoquinone concentration in the extract (5.2% w/w).
