Matricaria chamomilla – German/true chamomile (flowers, herbal ingredient)Matricaria chamomilla (syn. Chamomilla recutita) is German or true chamomile, an annual member of the daisy family whose flower heads are used as the medicinal part. The dried flowers contain essential oil, flavonoids, coumarins, and mucilage, which herbal and phytotherapy sources associate with soothing, mildly anti‑inflammatory, antispasmodic, and calming actions. Traditionally, chamomile is taken internally as tea, tincture, or powder, and used externally in baths, compresses, and mouth or skin rinses for mild digestive discomfort, nervous tension, and local irritation.Origin, properties, and compositionChamomile is widely grown in Europe and elsewhere as a medicinal and aromatic plant. Flower heads are harvested at full bloom and gently dried; from this material, powders, water‑alcohol extracts, and essential oil can be produced. The essential oil fraction is rich in sesquiterpenes such as (‑)‑α‑bisabolol, bisabolol oxides, farnesene, and chamazulene (formed from matricin during heating), while the polar fraction contains flavonoids (e.g. apigenin), coumarins, and other polyphenols. Overall, Matricaria chamomilla is a complex botanical matrix rather than a single isolated active compound.Role in dietary supplements/herbal productsIn dietary supplements, Matricaria chamomilla is used as a gentle calming and digestive herb, for example in sleep/relax blends and stomach‑comfort or “digestive” formulas. It may appear as chamomile flower powder, as standardised extract, or as part of multi‑herb teas; in cosmetics and personal care, chamomile derivatives are also used as fragrance and skin‑conditioning agents. Within supplement regulations, only appropriately worded, non‑medicinal health or structure/function statements are allowed; specific disease treatment claims would fall under medicinal product rules.Use, labelling, and precautionsLabels should clearly identify the botanical, e.g. “Chamomile (Matricaria chamomilla / Chamomilla recutita flower)” and specify the form (powder, extract) and any standardisation. Chamomile is generally regarded as safe in customary doses, but allergic reactions can occur, especially in people allergic to Asteraceae/Compositae plants such as ragweed, daisies, or marigolds. Caution is advisable when combining concentrated chamomile preparations with anticoagulant drugs, sedatives, or other potent medications because of reported potential interactions. Chamomile supplements are not medicines and do not replace medical diagnosis or treatment, nor do they substitute for a varied, balanced diet.Herbal disclaimerMatricaria chamomilla is a herbal/botanical ingredient containing pharmacologically active constituents; even well‑tolerated herbs can cause side effects or interactions in susceptible individuals. Information about traditional or researched uses is not personalised medical advice and must not replace consultation with a qualified healthcare professional. Chamomile‑containing products should be used as supportive dietary or herbal supplements, not as a substitute for medical care or healthy nutrition.
