The researchers say the starch granules and carbohydrate markers in the samples, plus evidence for plant compounds such as azulenes and coumarins, as well as possible evidence for nuts, grasses and even green vegetables, argue for a broader use of ingested plants than is often suggested by stable isotope analysis.
The principal components of the essential oil extracted from the flowers are the terpenoids a-bisabolol and its oxides and azulenes, including chamazulene, whereas the main constituents of the extracts prepared from the flowers include several phenolic compounds primarily the flavonoids apigenin, quercetin, patuletin, luteolin and their glucosides (Franke and Schilcher 2005; McKay and Blumberg 2006).
The former group is further divided into monocyclic and bicyclic compounds (bicyclo[3.1.0], bicyclo[3.1.1], bicyclo[4.1.0], bicyclo[4.4.0] (naphthalenes), bicyclo[5.3.0] (azulenes)) and the latter into furans, pyrans, bicyclo[3.2.1], bicyclo[5.1.0], and spiro compounds.
This contains chemicals called azulenes, which have intensely cooling and anti-inflammatory properties.
(7) Pharmacological measures for attenuating POST are inhalation of beclomethasone, (8) fluticasone and gargling with azulene sulfonate, (9) aspirin, ketamine (10) and licorice, (11) local spray and gargle of benzydamine hydrochloride (12) and intra cuff administration of alkalized lignocaine.
