Chamomile: Properties, Benefits, and Uses in Herbal Medicine
The properties of chamomile are far more extensive than one might think. Probably one of the best-known medicinal plants in the world, and often associated with evening relaxation, it has in fact been studied for many years for its pharmacological and healing properties. Research has in fact shed more light on its constituents and the mechanisms underlying its effects, revealing a complex action that involves the nervous system, the gastrointestinal tract, and inflammatory processes.
The plant
Its botanical name is Matricaria chamomilla (also Matricaria recutita), belonging to the Asteraceae (Compositae) family. It is an annual herbaceous plant, growing up to 50 cm tall, bearing flower heads, which constitute the medicinal part of the plant—that is, the part richest in beneficial and bioactive compounds.
The traditional use of chamomile is documented across various civilizations: in ancient Egypt as a fever-reducing remedy, in Greek and Roman medicine for gastrointestinal disorders, and in European tradition as a mild sedative. This long history of use has, in recent times, sparked the interest of the scientific community.
The active ingredients in chamomile, explained simply
Chamomile contains a complex mixture of compounds belonging to various chemical classes: a) flavonoids (apigenin, the main one, but also others, including luteolin and quercetin). Apigenin is particularly significant because it binds to GABA-A receptors in the central nervous system, contributing to its anxiolytic and antispasmodic effects; terpenes and sesquiterpenes, the main constituents of the essential oil (bisabolol and chamazulene—derived from matricin during distillation)—which are responsible for the anti-inflammatory, soothing, and partially antimicrobial properties; c) coumarins and mucilages, which contribute to the spasmolytic and mucosal-protective effects
Key concept: The effects of chamomile do not depend on a single molecule, but on the synergistic action of its components.
Scientifically proven benefits of chamomile
- Relaxing effect: in reality, this is a genuine anxiolytic effect and, more generally, a balancing effect on the nervous system, which also improves sleep and mood. Several clinical studies suggest that it is chamomile extracts themselves that act on the central nervous system
- Mechanism:apigenin interacts with GABA receptors → produces a calming effect similar to (but much milder than) that of benzodiazepines.
- Antispasmodic and digestive effects: Chamomile has a relaxing effect on the smooth muscles of the intestine, reducing spasms and alleviating dyspepsia and bloating; it is useful for irritable bowel syndrome (mild IBS). Mechanism: combined action of flavonoids and coumarins.
- Anti-inflammatory action: In vitro and in vivo studies show that the components of chamomile inhibit the inflammatory enzymes COX and LOX and reduce the production of pro-inflammatory cytokines. Chamazulene and bisabolol are among the main compounds responsible for this effect.
- Antioxidant activity: Flavonoids neutralize free radicals and reduce oxidative stress, potentially playing a role in cellular protection and aging processes.
- Dermatological effects: Topical application of compresses or creams containing chamomile extracts, essential oil, or pure bisabolol helps reduce erythema and irritation, providing a soothing effect on mild dermatitis. It also aids in wound healing. It is also used in mouthwashes and eye drops.
How to Use Chamomile Properly
The ways in which chamomile is used are numerous and vary widely across different populations
- The traditional infusion: on average , 2 g of dried flowers in a cup of boiling water (150 ml), steeped for 15 minutes, covered, to retain some of the volatile essential oil. The dosage should always be tailored to the individual.
- Various types of standardized extracts: medicinal tinctures, mother tinctures, liquid and dry extracts, and essential oils obtained by distillation. These allow for the selection of the right extract for each individual patient based on their condition, as well as a more precise dosage of the active ingredients.
But the traditional, home-style preparation we’re suggesting—and which we consider truly innovative—is chamomile tea!
While even sacred texts recommend an infusion made from the flower heads, we—based on over a decade of experience treating actual patients, as well as our knowledge of the plant’s phytochemistry and pharmacology—recommend and use a decoction to achieve greater extraction of the flavonoids and polysaccharides present. This yields excellent results, with a rapid and long-lasting anti-inflammatory and antispasmodic effect throughout the entire digestive tract.
It relieves pain and also promotes the healing of any erosive lesions.
In cases of acute gastritis, it should be drunk in small sips throughout the day; for colitis, several cups a day are recommended.
In cases of gastroesophageal reflux, whether or not a hiatal hernia is present, it can be prepared as a dry extract, either on its own or mixed with herbs high in mucilage, such as mallow or marshmallow.
Contraindications and warnings
Possible allergic reactions in individuals sensitive to Asteraceae (cross-reactivity with ragweed).
Drug interactions
• Potential interaction with anticoagulants (e.g., warfarin)
• Possible additive effect with sedatives
Pregnancy and breastfeeding: use should be evaluated on a case-by-case basis → medical consultation recommended.
Rare but possible paradoxical effects causing sleep disturbances and hyperexcitability.
Dr. Firenzuoli's opinion
According to Fabio Firenzuoli, an expert in clinical phytotherapy:
“Chamomile is one of the safest and most versatile plants, but it must be used with a rational approach.
Phytotherapy does not replace conventional medicine, but it can effectively complement it.”
It is ideally used as an adjunctive therapy; however, it often also allows for a reduction in the use of stomach-protecting medications
FAQ — Frequently Asked Questions About Chamomile
Is chamomile tea really effective for helping you sleep?
Yes, it has a mild effect. It is not a hypnotic but a relaxation modulator thanks to apigenin, which acts on the GABA-A receptors in the central nervous system.
How long does it take for chamomile tea to take effect?
It depends on how it's used:
- digestion → faster effect
- anxiety/sleep → gradual effect
Is it better to use chamomile as a tea or an extract?
- herbal tea → for daily use to promote well-being
- decoction → healing effect
- extracts → standardized extracts
Can chamomile tea replace medication?
No, while this is essential, it can certainly be used alongside such treatments and, over time, help reduce the need for them—always under medical supervision—but it should not replace prescribed therapies.
Is chamomile safe for daily use?
Generally speaking, yes, provided there are no contraindications.
Chamomile is a simple plant—but only at first glance: behind its widespread use lies a complex and well-studied phytochemical profile.
When used correctly, it can serve as a valuable natural aid for daily well-being, particularly for chronic conditions as well as acute issues related to stress, digestion, and inflammation.
