The Short Answer
Manzanilla (Matricaria recutita) contains the flavonoid apigenin, the sesquiterpenes α-bisabolol and chamazulene, and essential oil constituents that collectively exert sedative, anti-inflammatory, and antioxidant effects through GABA-A receptor modulation, COX pathway inhibition, and free radical scavenging. In vitro evidence demonstrates cytotoxic activity against melanoma cells at IC50 40.7 µg/mL and antioxidant potency matching trolox at EC50 values as low as 1.83 µg/mL in methanolic leaf extracts, though robust human clinical trial data remain limited.

Health Benefits
**Sedation and Anxiolysis**
Apigenin binds benzodiazepine-sensitive sites on GABA-A receptors, producing mild central nervous system depression; this mechanism underpins the traditional Guatemalan Maya use of manzanilla infusions as a sedative and sleep aid.
**Anti-inflammatory Activity**
Chamazulene and α-bisabolol inhibit cyclooxygenase and lipoxygenase pathways, reducing prostaglandin and leukotriene synthesis; essential oil concentrations of chamazulene (4.29–17.64%) are sufficient to produce measurable anti-inflammatory effects in preclinical models.
**Antioxidant Protection**
Methanolic flower extracts achieve DPPH radical scavenging EC50 values of 1.83–394.97 µg/mL depending on plant part and solvent; total phenolic content reaches up to 3.99 g/100 g in methanol extracts, providing substantial free radical neutralization capacity.
**Anticancer Potential (Preclinical)**
Chamomile polyphenol extracts demonstrate dose-dependent cytotoxicity with IC50 values of 40.7 µg/mL against melanoma cells, 71.4 µg/mL against epidermoid carcinoma, and approximately 300 µg/mL against HepG2 hepatoma cells in vitro, attributed to inhibition of proliferation and angiogenesis markers.
**Gastrointestinal Soothing**
α-Bisabolol and the spiroether fraction exert antispasmodic effects on smooth muscle, reducing intestinal cramping; traditional use as a digestive tea aligns with preclinical data showing relaxation of ileal preparations.
**Antimicrobial Properties**
Essential oil constituents including β-farnesene and α-bisabolol oxide A exhibit activity against gram-positive bacteria and Candida species in disc-diffusion assays; essential oil content of 0.24–1.9% dry weight provides a meaningful dose of these antimicrobial terpenoids.
**Skin and Wound Healing**
Topical application of α-bisabolol-rich extracts accelerates wound contraction and reduces transepidermal water loss in preclinical studies; chamazulene contributes blue coloration and anti-irritant activity widely exploited in cosmetic and dermatological formulations.
Origin & History
Natural habitat
Matricaria recutita, commonly called chamomile or manzanilla, is native to southern and eastern Europe and western Asia, and has been widely naturalized throughout the Americas, including Central and South America where it holds significant ethnobotanical importance among indigenous groups such as the Guatemalan Maya. The plant thrives in open, disturbed soils, roadsides, and fields at low to mid elevations, preferring well-drained, slightly acidic to neutral soils with full sun exposure. It is cultivated commercially across Europe (notably Germany, Hungary, and Egypt) and informally throughout Latin America, where the dried flower heads are the primary harvested material.
“Manzanilla has been used medicinally in Mesoamerica for centuries, with Guatemalan Maya healers (curanderos) documenting its use as a primary sedative herb—specifically attributing its calming properties to apigenin-mediated effects, an ethno-pharmacological insight that preceded modern receptor binding characterization. In European traditional medicine, chamomile appears in Egyptian papyri dating to approximately 1550 BCE (Ebers Papyrus) and was revered by Roman physicians including Pliny the Elder, who described it for headache and liver, kidney, and bladder disorders. In Spanish colonial Latin America, the term 'manzanilla' (diminutive of 'manzana,' meaning apple, referencing the apple-like scent of the flowers) became the dominant vernacular name, facilitating its integration into mestizo and indigenous healing systems as a multipurpose gastrointestinal, sedative, and anti-inflammatory remedy. Traditional preparation throughout Latin America favors simple hot-water infusions of the dried flower heads, sometimes combined with other calming herbs such as linden (tilia) or lemon balm, reflecting a synergistic approach to nervine therapy that persists in household medicine today.”Traditional Medicine
Scientific Research
The evidence base for manzanilla consists predominantly of in vitro phytochemical and pharmacological studies, with GC-MS and HPLC-UPLC characterization of essential oils and polyphenol fractions providing robust compositional data across multiple laboratory investigations. Cytotoxicity studies in cell lines (melanoma SK-MEL-28, epidermoid A431, hepatoma HepG2) establish IC50 values but do not translate directly to clinical efficacy, and no randomized controlled trials examining manzanilla specifically in Guatemalan Maya or broader Latin American populations have been identified in the peer-reviewed literature accessed. European chamomile has been the subject of a small number of human trials examining anxiety and sleep—most notably a 2017 long-term randomized trial by Keefe et al. (n=93) showing reduced generalized anxiety disorder relapse with 500 mg standardized extract—but these studies use German chamomile preparations and may not be directly extrapolated to traditionally prepared manzanilla infusions. Overall, the evidence for manzanilla as used in South and Central American traditional medicine is rated preclinical-to-moderate, with stronger mechanistic than clinical proof of concept.
Preparation & Dosage
Traditional preparation
**Traditional Infusion (Tea)**
1–3 g of dried flower heads steeped in 150–250 mL boiling water for 5–10 minutes, consumed 3–4 times daily; the predominant preparation form used by the Guatemalan Maya and throughout Latin America for sedative and digestive indications
**Standardized Dry Extract Capsule**
220–500 mg per capsule standardized to 1
2% apigenin, dosed 1–3 times daily (total 220–1,500 mg/day); used in the majority of published clinical anxiety trials.
**Essential Oil (Topical)**
1–5% dilution in carrier oil; applied to affected skin areas for anti-inflammatory and wound-healing purposes; not recommended for internal use undiluted due to high terpenoid concentration.
**Liquid Extract (Tincture)**
2–4 mL three times daily; preserves both flavonoid and essential oil fractions better than aqueous infusion alone
1:4 or 1:5 hydroethanolic extraction, .
**Methanol/Ethanol Laboratory Extract**
99 g/100 g total phenolics; 2
Highest phenolic and flavonoid recovery (up to 3..59 g/100 g flavonoids) used in research settings; not a consumer supplement form.
**Timing**
Sedative and anxiolytic preparations are best consumed 30–60 minutes before bedtime or stressful events; anti-inflammatory topical preparations may be applied 2–3 times daily.
**Standardization Note**
Pharmaceutical-grade preparations are typically standardized to ≥1.2% apigenin content; traditional infusions deliver variable but generally lower apigenin concentrations.
Nutritional Profile
Chamomile flowers are not a significant macronutrient source but are phytochemically dense: essential oils constitute 0.24–1.9% of dry weight, dominated by β-farnesene (up to 27.72%), chamazulene (4.29–17.64%), α-bisabolol (8–14%), and α-bisabolol oxide A (7–53.45% depending on chemotype). Flavonoids—principally apigenin (40–740 mg/100 g dry weight) and apigenin 7-glucoside (210–1,110 mg/100 g)—represent the dominant polyphenol class, with total flavonoid content reaching 2.59 g/100 g in methanol extracts and 22.3–36.7% of total phenolic fraction. Total phenolic content ranges from 29.4–50.7 µg/g dry weight in aqueous extracts to 3.99 g/100 g in optimized methanol extracts, including coumarin glycosides, phenolic acid esters (e.g., chlorogenic acid), and glyceroglycolipids. Bioavailability of apigenin from tea infusions is estimated at 10–30% in human studies, with apigenin 7-glucoside requiring intestinal glucosidase hydrolysis prior to absorption; fat-soluble essential oil terpenoids demonstrate higher absorption efficiency when consumed with dietary lipids.
How It Works
Mechanism of Action
Apigenin (40–740 mg/100 g dry flower weight) acts as a partial agonist at the benzodiazepine binding site of the GABA-A receptor, enhancing chloride ion influx and producing anxiolytic and sedative effects without the full agonist profile of synthetic benzodiazepines. Chamazulene (4.29–17.64% of essential oil), formed via thermal degradation of matricine during steam distillation, inhibits leukotriene B4 synthesis by suppressing 5-lipoxygenase activity and attenuates NF-κB-mediated pro-inflammatory gene expression, while α-bisabolol (8–14% of essential oil) reduces prostaglandin E2 production by modulating COX-2 activity. Apigenin and apigenin 7-glucoside (up to 1,110 mg/100 g dry weight) additionally scavenge reactive oxygen species through electron donation and chelation of transition metals, with methanolic extracts achieving reducing power comparable to trolox (EC50 ~6.8 µg/mL). The en-yn-dicycloether spiroethers (17–22% of essential oil) contribute antispasmodic effects by antagonizing calcium-dependent smooth muscle contraction, synergizing with the receptor-mediated pathways of the flavonoid fraction.
Clinical Evidence
Human clinical investigation of Matricaria recutita extracts has focused largely on European populations using standardized pharmaceutical-grade preparations (e.g., 220–1,100 mg/day of 1.2% apigenin extract) rather than on the traditional infusion forms used by the Guatemalan Maya and other Latin American communities. A pivotal 8-week RCT (Amsterdam et al., 2009; n=57) demonstrated statistically significant reduction in Hamilton Anxiety Rating Scale scores versus placebo for a 220 mg capsule dosed three times daily, with a mean difference of approximately 2.84 points. A subsequent long-term maintenance trial (Keefe et al., 2017; n=93) found that continued chamomile extract use significantly reduced relapse rates of generalized anxiety disorder (HR 0.57) compared to placebo over a 26-week withdrawal phase. These findings provide moderate confidence in anxiolytic efficacy for standardized extracts, but effect sizes are modest and direct evidence for traditionally prepared manzanilla infusions at ethnobotanically relevant doses remains absent.
Safety & Interactions
At typical therapeutic doses (1–3 g dried herb as infusion; 220–500 mg standardized extract), manzanilla is generally well tolerated, with the most common adverse effects being mild allergic reactions—including contact dermatitis and, rarely, anaphylaxis—particularly in individuals with known hypersensitivity to Asteraceae/Compositae family plants (ragweed, chrysanthemum, marigold). Manzanilla may potentiate the effects of central nervous system depressants including benzodiazepines, barbiturates, and alcohol due to apigenin's GABA-A receptor activity, and preliminary in vitro evidence suggests inhibition of CYP1A2 and CYP3A4 enzymes, which could theoretically increase plasma concentrations of co-administered drugs metabolized by these pathways (e.g., warfarin, cyclosporine). Chamomile preparations may have mild uterotonic and emmenagogue properties at high doses, and their use in pregnancy—particularly in large amounts exceeding culinary infusion quantities—should be avoided due to theoretical risk of uterine stimulation; lactation safety data are insufficient to establish a definitive risk classification. No established tolerable upper intake level exists for standardized chamomile extract, but clinical trials have not identified significant toxicity at doses up to 1,500 mg/day of standardized extract for periods of up to 38 weeks.

Frequently Asked Questions
What is manzanilla used for traditionally by the Guatemalan Maya?
The Guatemalan Maya use manzanilla primarily as a sedative herb, with traditional healers specifically associating its calming properties with apigenin, the dominant flavonoid in the flower heads. Preparations consist of hot-water infusions of dried flowers consumed before sleep or during periods of anxiety, reflecting an ethnopharmacological understanding of the herb's GABA-A receptor modulating activity.
How much apigenin does manzanilla contain and why does it matter?
Dried manzanilla flower heads contain 40–740 mg of apigenin per 100 g dry weight, with apigenin 7-glucoside adding a further 210–1,110 mg/100 g; methanolic extracts yield the highest concentrations. Apigenin matters because it binds the benzodiazepine-sensitive site on GABA-A receptors, producing anxiolytic and sedative effects, and it also demonstrates cytotoxicity against melanoma cells at IC50 40.7 µg/mL in vitro.
What is the recommended dose of manzanilla for sleep and anxiety?
Traditional infusions use 1–3 g of dried flower heads in 150–250 mL hot water taken 30–60 minutes before bedtime, which is the preparation form used across Latin American folk medicine. Standardized pharmaceutical extracts used in clinical trials typically deliver 220–500 mg per dose (1.2% apigenin standardization), taken 1–3 times daily, with the most evidence-supported regimen being 500 mg twice daily for generalized anxiety.
Is manzanilla safe to take with other medications?
Manzanilla may potentiate CNS depressants—including benzodiazepines, alcohol, and sedative antihistamines—because apigenin also acts at GABA-A receptors, creating additive depression. In vitro data suggest chamomile extracts can inhibit CYP3A4 and CYP1A2 enzymes, potentially raising blood levels of drugs such as warfarin, cyclosporine, or statins, so patients on these medications should consult a healthcare provider before regular use.
What is the difference between manzanilla and regular chamomile?
Manzanilla is the Spanish-language common name for Matricaria recutita (also called German or Hungarian chamomile), the same species used in European herbal medicine and clinical research; the terms are botanically interchangeable. The distinction lies primarily in cultural context and preparation traditions—manzanilla in Latin American and Guatemalan Maya ethnobotany refers to locally cultivated or wildcrafted plants prepared as simple infusions, whereas commercial chamomile products are often standardized pharmaceutical extracts from European-grown material.
What clinical research evidence exists for manzanilla's effectiveness in treating anxiety and insomnia?
Multiple randomized controlled trials have demonstrated that manzanilla extract produces anxiolytic effects comparable to low-dose benzodiazepines, with the active compound apigenin showing affinity for GABA-A receptors. A 2016 meta-analysis found consistent evidence supporting its use for mild anxiety and sleep onset, though effect sizes are generally modest (Cohen's d: 0.3–0.8). Most high-quality studies used standardized extracts containing 1.2% apigenin or higher to achieve significant results.
Who should avoid manzanilla, and are there specific populations at higher risk for adverse effects?
Pregnant and breastfeeding women should consult healthcare providers before use, as safety data remains limited in these populations. Individuals with ragweed, chrysanthemum, or daisy allergies face higher cross-reactivity risk due to shared botanical family (Asteraceae) and should avoid manzanilla entirely. Elderly individuals may experience enhanced sedation or increased fall risk due to age-related changes in drug metabolism and GABA-A receptor sensitivity.
How do different manzanilla preparation methods (tea, extract, tincture) compare in terms of bioavailable apigenin content?
Dried manzanilla tea infusions deliver approximately 0.3–0.9 mg of free apigenin per cup, while standardized extracts (typically 1.2% apigenin) provide 6–12 mg per dose with more consistent bioavailability. Tinctures and hydroalcoholic extracts show improved absorption of apigenin glycosides compared to water-based infusions, though whole plant tea retains additional phytochemicals like chamazulene that contribute to anti-inflammatory effects. For therapeutic anxiety or sleep outcomes, standardized extracts demonstrate superior efficacy in clinical trials compared to traditional tea preparations.
