**2.11 Chamomile**

Chamomile, known as *Matricaria recutita*, contains volatile oils, flavonoids, apigenin, luteolin, and quercetin [43]. It has an anti-inflammatory property that is as effective as a mouthwash for gingivitis and periodontal disease. There was a zone of inhibition when tested against *P. gingivalis* (**Table 1**, [44]). However, eucalyptus oil was the most effective, followed by tea tree oil, chamomile oil, and turmeric oil [45]. It can be used in management of burning mouth syndrome cases and as an irrigate solution (**Table 1**, [46]). It can be used topically in the treatment of eczema [43–46]. In fact, a randomized clinical trial found it to be equivalent to hydrocortisone cream [43–46]. However, it can cause allergic reactions which included bronchial constriction and skin reactions [43]. It is controversial to use with a pregnant women since it caused a newborn death in a single case report.
