The Short Answer
Vitex negundo leaves contain iridoid glucosides (notably agnuside at ~3.04% dry weight), flavonoids (vitexin, isovitexin, isoorientin), and the sesquiterpenoid viridiflorol, which together modulate inflammatory mediators, free radical scavenging, and analgesic pathways. In preclinical mouse peritoneal inflammation models, leaf extract at 9.6–28.8 g/kg demonstrated chronic anti-inflammatory efficacy comparable to methylprednisolone at 10 mg/kg, though human clinical trial data remain sparse.

Health Benefits
**Anti-inflammatory Activity**
Leaf extracts containing agnuside and viridiflorol suppress inflammatory mediators in peritoneal models with potency approaching corticosteroid benchmarks; this underlies its traditional use for joint pain and swelling in Filipino and Malaysian folk medicine.
**Analgesic and Antipyretic Effects**
The leaves exhibit documented analgesic and antipyretic properties attributed to flavonoids such as vitexin and isoorientin, which modulate prostaglandin synthesis pathways, providing relief from pain and fever consistent with its hilot and Ayurvedic applications.
**Antioxidant Protection**
Phenolic compounds including chlorogenic acid, isoorientin, cynaroside, and scutellarin contribute to significant free radical scavenging activity; phenolic content in leaf extracts measures approximately 2.70 mg/g dry weight, correlating with antioxidant capacity.
**Antimicrobial and Anti-tuberculosis Potential**
Viridiflorol, a sesquiterpenoid prominent in leaf extracts, shows documented activity against Mycobacterium tuberculosis in vitro, alongside broader antimicrobial effects attributed to the volatile oil fraction containing epiglobulol (30.31%) and terpinen-4-ol (9.42%).
**Anthelmintic Properties**
Leaf preparations carry traditional and pharmacologically supported anthelmintic activity, with bitter iridoid glucosides such as agnuside proposed as key mediators disrupting parasitic neuromuscular function.
**Prolactin Modulation**
Extracts have been shown to reduce serum prolactin levels in experimental models of hyperprolactinemia and mastodynia, a mechanism shared with the related species Vitex agnus-castus and attributed to dopaminergic activity of the diterpene and iridoid fraction.
**Respiratory and Cough Relief**
In Malaysian and Filipino ethnomedicine, aromatic leaf preparations are used to alleviate cough and bronchial congestion; volatile components including gamma-elemene and delta-iraleine may contribute bronchodilatory and expectorant effects, though controlled clinical evidence is lacking.
Origin & History
Natural habitat
Vitex negundo L. is native to tropical and subtropical Asia, distributed across the Philippines, Malaysia, India, Sri Lanka, China, and parts of East Africa. The shrub thrives in scrublands, riverbanks, forest margins, and disturbed habitats at elevations from sea level to approximately 1,500 meters, tolerating a range of soil types. In the Philippines it is cultivated and wildcrafted for use in traditional hilot medicine, while in China it is widely incorporated into food, agricultural, and medicinal product systems.
“Vitex negundo, known as lagundi in the Philippines, nirgundi in India, and mingmu in parts of China, has been used medicinally for over two millennia across Asian healing traditions. In Filipino hilot (traditional massage and herbal medicine), lagundi leaf preparations are among the most widely prescribed remedies for cough, asthma, pain, and fever, and the Philippine Department of Health has officially recognized lagundi as one of ten priority medicinal plants in its national herbal medicine program. In Ayurvedic medicine, nirgundi is classified as a vata-pitta pacifier and prescribed for arthritis, inflammatory conditions, and nervous disorders, with preparations including leaf juice, poultice, and medicated oil described in classical texts such as the Charaka Samhita. Malaysian traditional healers employ the plant for respiratory ailments and musculoskeletal pain under regional vernacular names, reinforcing its pan-Southeast Asian medicinal significance.”Traditional Medicine
Scientific Research
The evidence base for Vitex negundo consists predominantly of in vitro phytochemical characterization studies and preclinical rodent experiments, with no published large-scale randomized controlled human trials identified in the current literature. One notable preclinical study demonstrated that leaf extract at doses of 9.6 g/kg and 28.8 g/kg leaf weight-to-body weight produced significant chronic anti-inflammatory effects comparable to methylprednisolone at 10 mg/kg in a mouse peritoneal model, though translation to human dosing remains unestablished. GC-MS analyses of methanolic leaf extracts and in vitro callus cultures have systematically characterized the phytochemical profile, revealing that octadecadienoic acid constitutes 21.93% of wild-leaf extracts and up to 47.79% in green callus cultures, approximately doubling in vitro. The overall evidence strength is low-to-moderate for preclinical bioactivity, and clinicians should regard efficacy claims as hypothesis-generating pending robust human trials.

Nutritional Profile
Vitex negundo leaves contain phenolic compounds at approximately 2.70 mg/g dry weight, protein at 2.49 mg/g dry weight, and phytosterols at 1.1 mg/g dry weight. The dominant phytochemical by mass in wild-leaf methanolic extracts is octadecadienoic acid (linoleic acid derivative) at 21.93%, alongside hexadecanoic acid (palmitic acid) and methyl ester derivatives contributing to the fatty acid fraction. Bioactive iridoid agnuside is present at 3.04 ± 0.02% in dried leaves; flavonoids vitexin, isovitexin, isoorientin, and scutellarin are present in smaller but pharmacologically relevant concentrations. The volatile oil fraction (approximately 0.1–0.5% of dry leaf mass) is dominated by epiglobulol (30.31%), delta-iraleine (10.34%), terpinen-4-ol (9.42%), and gamma-elemene (5.72%), contributing to aromatic and antimicrobial properties. Bioavailability data for individual constituents in humans are not yet established.
How It Works
Mechanism of Action
The anti-inflammatory mechanism of Vitex negundo involves suppression of pro-inflammatory cytokine cascades and inhibition of cyclooxygenase-mediated prostaglandin synthesis, with agnuside (iridoid glucoside) and flavonoids such as vitexin and isovitexin identified as primary bioactive agents. Viridiflorol, a bicyclic sesquiterpenoid, exerts antioxidant activity by scavenging reactive oxygen species and has demonstrated anti-mycobacterium tuberculosis activity, likely through disruption of mycobacterial cell wall integrity. The prolactin-lowering effect is attributed to dopaminergic receptor agonism by diterpenes and iridoids, mirroring the mechanism established for Vitex agnus-castus constituents. Phenolic acids, particularly chlorogenic acid and scutellarin, further contribute to antioxidant defense by chelating metal ions and donating hydrogen atoms to neutralize lipid peroxyl radicals.
Clinical Evidence
No phase II or III randomized controlled human trials have been published specifically evaluating Vitex negundo leaf extract for pain, cough, or anti-inflammatory endpoints as of current literature review. Available clinical-adjacent data derive from animal models showing dose-dependent anti-inflammatory responses and from ethnopharmacological surveys documenting consistent traditional use across the Philippines, Malaysia, India, and China. The most quantified preclinical outcome is chronic peritoneal inflammation suppression in mice at 9.6–28.8 g/kg, benchmarked against methylprednisolone at 10 mg/kg, yielding comparable effect sizes. Confidence in translational efficacy remains low; the plant's therapeutic profile is considered biologically plausible based on identified phytochemical mechanisms, but human dose-response, safety, and pharmacokinetic data require formal investigation.
Safety & Interactions
Formal human safety and toxicology studies for Vitex negundo are limited; traditional long-term use across multiple cultures suggests reasonable tolerability at typical decoction doses, but no maximum safe human dose has been established through controlled trials. Given the plant's documented prolactin-suppressing activity, it should be used with caution in individuals taking dopamine antagonists (antipsychotics such as haloperidol or risperidone) or prolactin-dependent therapies, as additive dopaminergic effects are pharmacologically plausible. Pregnancy and lactation contraindications are implied by the prolactin-lowering and potential uterotonic properties described in traditional literature and paralleled by the better-studied Vitex agnus-castus; use during pregnancy or breastfeeding should be avoided until safety is established. The bitter and pungent leaf constituents may cause gastrointestinal discomfort at high doses; individuals with hormone-sensitive conditions or those on corticosteroid or immunosuppressive therapy should seek medical guidance before use.

Frequently Asked Questions
What is Vitex negundo (lagundi) used for?
Vitex negundo leaves are used primarily for cough, asthma, pain, and fever in Filipino hilot and Malaysian traditional medicine, and for arthritis and inflammatory conditions in Ayurvedic practice. The Philippine Department of Health has officially recognized lagundi as one of ten priority medicinal plants, with preparations typically made as leaf decoctions consumed 2–3 times daily. Its bioactive compounds including agnuside, vitexin, and viridiflorol provide the pharmacological basis for these traditional applications.
What are the active compounds in Vitex negundo?
The primary bioactive compounds in Vitex negundo leaves include the iridoid glucoside agnuside (approximately 3.04% of dried leaf), flavonoids vitexin, isovitexin, isoorientin, and scutellarin, and the sesquiterpenoid viridiflorol. The volatile oil fraction contains epiglobulol (30.31%), delta-iraleine (10.34%), and terpinen-4-ol (9.42%) as dominant components. Octadecadienoic acid represents the highest concentration phytochemical by mass at 21.93% in wild-leaf methanolic extracts.
Is Vitex negundo the same as Vitex agnus-castus (chaste tree)?
Vitex negundo and Vitex agnus-castus are closely related species within the genus Vitex but are distinct plants with different geographical origins and phytochemical profiles. Vitex agnus-castus originates from the Mediterranean and has more extensive human clinical trial data for PMS and hyperprolactinemia. Vitex negundo is native to tropical Asia, contains a higher proportion of iridoid agnuside and specific sesquiterpenoids like viridiflorol, and has a broader traditional use profile including respiratory and musculoskeletal conditions, though it lacks equivalent clinical trial support.
Does Vitex negundo have anti-inflammatory effects supported by research?
Preclinical mouse studies demonstrate that Vitex negundo leaf extract at doses of 9.6 g/kg and 28.8 g/kg body weight produces chronic anti-inflammatory effects statistically comparable to methylprednisolone at 10 mg/kg in peritoneal inflammation models. The mechanism involves flavonoid-mediated inhibition of prostaglandin synthesis and agnuside-linked suppression of pro-inflammatory cytokine pathways. However, no human randomized controlled trials have confirmed these effects at safe and practical human doses, so the evidence remains at a preclinical stage.
Is Vitex negundo safe during pregnancy?
Vitex negundo is not considered safe during pregnancy based on its documented prolactin-suppressing activity, which parallels the better-characterized uterotonic and hormonal effects of the related Vitex agnus-castus. Traditional herbal texts and ethnobotanical accounts in Ayurvedic and Filipino medicine advise against its use during pregnancy. Women who are pregnant, planning pregnancy, or breastfeeding should avoid Vitex negundo supplementation until formal human safety studies are conducted.
What is the most effective form of Vitex negundo for pain and inflammation?
Leaf extracts standardized for active compounds like agnuside and viridiflorol demonstrate the strongest anti-inflammatory and analgesic effects in research models, outperforming whole leaf powder preparations. Standardized extracts allow consistent dosing of bioactive constituents and show potency approaching corticosteroid benchmarks in suppressing inflammatory mediators. Aqueous and ethanol-based extracts appear most effective at preserving the volatile oils and alkaloids responsible for pain relief.
Does Vitex negundo interact with common pain medications or anti-inflammatory drugs?
Limited clinical interaction data exists for Vitex negundo with NSAIDs or corticosteroids, though its mechanism of suppressing inflammatory mediators suggests potential additive effects rather than direct drug conflicts. Anyone taking prescription anti-inflammatory medications should consult a healthcare provider before combining with Vitex negundo to avoid unintended synergistic activity. No major drug interactions have been documented with acetaminophen, ibuprofen, or other over-the-counter analgesics, but individual variations in metabolism warrant caution.
Who benefits most from using Vitex negundo for joint pain and inflammatory conditions?
Vitex negundo is traditionally used by individuals seeking natural alternatives to NSAIDs for chronic joint pain, arthritis symptoms, and inflammatory swelling, particularly in Filipino and Malaysian populations with established ethnobotanical use. Those with mild-to-moderate inflammation may experience greater benefit than those with severe inflammatory conditions requiring prescription-strength treatment. People with fever accompanied by inflammation or pain may see dual benefit from its documented antipyretic and analgesic properties.
