Chamomile Extract

What it is

German chamomile (Chamomilla recutita, also Matricaria chamomilla) is an annual plant of the Asteraceae family and one of the most thoroughly studied medicinal plants in Europe. It has been used medicinally since the 1st century BC: Dioscorides recommended chamomile baths for inflammations, while Egyptians dedicated it to the sun god Ra for its "golden" fever-reducing effect.

For dental applications, the extract of flower heads is used — rich in three key bioactive agents: azulene (a chamazulene derivative formed during steam distillation), apigenin (a flavonoid) and (−)-alpha-bisabolol (a sesquiterpene alcohol). Chamazulene — which gives chamomile essential oil its intense blue colour — is technically a distillation artefact, yet retains anti-inflammatory properties.

How it works

COX-1 and COX-2 inhibition. Apigenin competitively blocks both cyclooxygenase isoenzymes, reducing synthesis of prostaglandins PGE₂ and thromboxane B₂. COX-1 blockade reduces basal inflammation; COX-2 blockade addresses the acute stimulus response. Unlike synthetic NSAIDs, mouthwash concentrations do not reach the threshold for systemic effects.

STAT3 inhibition. Apigenin suppresses the STAT3 signalling pathway that regulates chronic inflammation. Bhaskaran et al. (2012) showed reductions in IL-6 and TNF-α at apigenin concentrations of 20–40 μM — achievable in a mouthwash.

Bisabolol and regeneration. (−)-α-bisabolol accelerates keratinocyte and fibroblast migration to injury sites — speeding epithelialisation of ulcers and mucosal micro-abrasions. This mechanism explains why chamomile was traditionally used for stomatitis and wound healing.

Azulene. Chamazulene reduces histamine release from mast cells — the antihistamine component is particularly valuable in allergic mucosal reactions and reactions to orthodontic appliances.

Efficacy

Martins et al. (2009) in a randomised trial showed that chamomile rinses reduced the severity of oral mucositis in oncology patients undergoing chemotherapy — a context involving maximal mucosal damage. The chamomile group demonstrated reduced pain scores and accelerated epithelialisation compared to control.

For gingivitis: systematic reviews confirm reductions in inflammation indices with regular use, though the effect is milder than baicalin or chlorhexidine. Chamomile's key advantage is zero side effects with long-term use.

Safety

One of the most thoroughly studied botanical ingredients. Rare cases of allergic contact dermatitis are described in individuals sensitised to Asteraceae (Compositae) — ragweed, chrysanthemum, dandelion. For people without Asteraceae allergy, chamomile is safe even with daily use.

CIR Expert Panel and SCCS (EU) have confirmed the safety of the extract at cosmetic concentrations.

Role in the QDRO formula

Chamomile is a gentle anti-inflammatory "background" agent working at the COX level without irritation — ideal for sensitive gums in the v.daily line. In synergy with bisabolol (which we also consider separately) it enhances the regenerative profile. Stable in aqueous formulas at pH 4.5–7 — technologically preferred for foaming toothpastes.
