The material complies with the European Pharmacopoeia [12].

2.5.1.2 Constituents

The main characteristic constituents of matricaria flower are the essential oil and flavone derivatives [21, 32, 60, 98, 116] such as apigenin-7-glucoside (approximately 0.5%) [32].

The essential oil contains approximately 50% of the sesquiterpenes (-)-a-bisabolol and its oxides A and B [98], bisabolonoxide, up to 25% of cis- and trans-en-yn-dicycloethers (or spiroethers) [32], and matricin, which is converted to chamazulene on distillation (up to 15%) [32].

Other constituents of matricaria flower include coumarins (herniarin and umbelliferone) [21, 32, 98, 116], phenolic acids [21, 32, 98], and polysaccharides (up to 10%) [21, 32, 52, 98].

2.5.1.3.12 Pregnancy and lactation No harmful effects reported

2.5.1.3.13 Effects on ability to drive and use machines None known

2.5.1.3.14 Undesirable effects

Rare cases of contact allergy have been reported in persons with known allergy to Artemisia species [98]. Matricaria flower of the bisabolol oxide B-type can contain traces of the contact allergen anthecotulide [27, 62, 98]. Matricaria recutita L. possesses a much lower allergenic potential than other chamomile species, and therefore allergic reactions to Matricaria must be considered as extremely rare. Most of the described allergic reactions to Matricaria were due to contamination with Anthemis cotula or related Anthemis species, which contain high amounts of anthecotulide. However, in cases where Matricaria contact allergy has been acquired, cross-reactions to other sesquiterpene lactone-containing plants are common [62].
