The Short Answer
Lantana camara contains triterpenoids (notably ursolic acid derivatives), flavonoids, phenolics, and the hepatotoxic pentacyclic triterpene acids collectively termed lantadenes, which modulate inflammatory enzymes including COX-2, iNOS, and 5-LOX while exerting free-radical scavenging activity. Clinical evidence remains confined to a single uncontrolled hemorrhoid study using 500 mg/kg dry aqueous leaf extract capsules, with no randomized controlled trials validating efficacy or safety in humans.

Health Benefits
**Anti-inflammatory Activity**
Phenolic compounds and ursolic acid derivatives in leaf and flower extracts inhibit COX-2, iNOS, 5-LOX, and protein kinase C (PKC) pathways in preclinical models, reducing pro-inflammatory mediator production; however, these effects have not been confirmed in human clinical trials.
**Antioxidant Properties**
Flower extracts demonstrate a total phenolic content of 614.79 ± 1.25 mg GAE/g dry weight, and leaf extracts exhibit DPPH radical scavenging with an IC50 of 316.87 ppm in ethanol preparations, suggesting meaningful but unstandardized free-radical neutralization capacity.
**Traditional Wound and Skin Support**
Poultices prepared from crushed Lantana camara leaves have been applied ethnobotanically in Cambodia, Thailand, India, and Africa to treat skin infections, wounds, and eczematous lesions, with antimicrobial activity attributed to membrane-disrupting terpenoids and phenolics.
**Antidiabetic Potential (Preclinical)**
Ursolic acid and its glucosylated derivatives have demonstrated blood glucose reduction in rodent models, likely through enhanced peripheral glucose uptake and inhibition of α-amylase and α-glucosidase enzymes; no human pharmacokinetic or efficacy data exist.
**Antimicrobial Effects**
GC-MS-identified volatiles including loliolide and phytol, alongside alkaloids and flavonoids, show in vitro inhibition of plant pathogens such as Magnaporthe oryzae and Xanthomonas spp. via disruption of membrane integrity and interference with MAPK1 and PDF enzyme targets.
**Antipyretic and Antirheumatic Traditional Use**
Leaf decoctions have been employed in Cambodian and Thai folk medicine for fever reduction and rheumatic joint pain, with experimental anti-inflammatory enzyme inhibition (XO, AChE) providing a partial mechanistic rationale for these traditional applications.
**Anti-haemorrhoidal Activity**
A preliminary human study evaluated dry aqueous leaf extract capsules (500 mg/kg plus 100 mg/kg lactose) for hemorrhoid symptoms and reported therapeutic activity; however, the absence of control groups, documented sample size, and statistical data makes this evidence inconclusive.
Origin & History
Natural habitat
Lantana camara is native to the tropical Americas, spanning Mexico, Central America, and the Caribbean, but has naturalized aggressively across Southeast Asia, Africa, India, and Australia, earning designation as one of the world's most invasive plant species. It thrives in disturbed habitats, roadsides, forest margins, and degraded agricultural land at elevations from sea level to approximately 2,000 meters, tolerating a wide range of soils and rainfall regimes. In Cambodia, Thailand, India, and sub-Saharan Africa, it grows abundantly without deliberate cultivation, and traditional communities harvest it opportunistically from wild stands for medicinal use.
“Lantana camara has a well-documented history of medicinal use spanning at least three centuries across its introduced range in Asia and Africa, where indigenous healers incorporated it rapidly after the plant's spread from tropical America. In Cambodian and Thai traditional medicine, leaf poultices are applied to rheumatic joints and infected skin lesions, while decoctions are used as antipyretics for malarial fevers and as treatments for diarrhea and respiratory complaints. In India, Ayurvedic and folk practitioners employed the plant under various regional names (phanphuli, gandh pana) for wound healing, leprosy, scabies, and tetanus, with the leaves and roots prepared as pastes, decoctions, and inhalations depending on the indication. Across West Africa, the plant is similarly used for malaria, skin diseases, and muscle pain, reflecting a convergent pattern of ethnomedicinal application that likely arose independently in multiple regions following the plant's introduction, yet none of these traditional applications have been subjected to rigorous prospective clinical validation.”Traditional Medicine
Scientific Research
The body of evidence for Lantana camara consists overwhelmingly of in vitro assays and small animal studies, with no large-scale, randomized, placebo-controlled human trials documented in the peer-reviewed literature as of the most recent systematic review of its pharmacology. The sole reported human study evaluated dry aqueous leaf extract capsules in an unspecified number of hemorrhoid patients, providing no control group, blinding procedure, p-values, or effect size data, rendering it insufficient to support evidence-based clinical recommendations. Preclinical antidiabetic data in rat models, anti-inflammatory enzyme inhibition studies, and antimicrobial minimum inhibitory concentration assays constitute the strongest available evidence, yet these findings suffer from species extrapolation limitations and absence of pharmacokinetic characterization in humans. The research landscape is further complicated by significant phytochemical variability across geographic populations, harvesting seasons, and extraction solvents (ethanol vs. methanol at 1:10–1:20 w/v ratios), making cross-study comparisons unreliable and standardization for clinical use currently impossible.
Preparation & Dosage
Traditional preparation
**Dry Aqueous Leaf Extract Capsules (Experimental)**
500 mg/kg body weight used in a single uncontrolled hemorrhoid study; this dose has not been validated in RCTs and is not recommended for human use outside controlled research settings
**Ethanolic/Methanolic Maceration Extract**
Plant powder dissolved in 70–95% ethanol or methanol at a 1:10 to 1:20 (w/v) ratio, macerated at room temperature for 24–72 hours, then filtered; used exclusively for laboratory bioassay and not standardized for supplemental consumption.
**Traditional Leaf Decoction (Topical/External)**
Fresh or dried leaves boiled in water and applied as a warm poultice to wounds, skin infections, or swollen joints in Cambodian and Thai ethnomedicine; internal ingestion of decoctions is associated with toxicity risk and is not validated.
**Standardization**
No pharmacopoeial monograph or standardization percentage exists for any Lantana camara extract; lantadene content is not routinely quantified and varies substantially by geographic origin, plant part, and season.
**Effective Dose Range**
No safe or effective human dose has been established; all dosing referenced in literature is experimental, weight-based (mg/kg), and derived from animal models or a single unstandardized human study.
**Timing and Administration Notes**
No evidence-based guidance on dosing frequency, timing relative to meals, or duration of use exists; internal use is contraindicated due to hepatotoxicity risk.
Nutritional Profile
Lantana camara is not a food ingredient and has no established nutritional profile as a macronutrient or micronutrient source; it is not consumed as part of any traditional diet and is categorically distinct from edible botanicals. Phytochemically, triterpenoids dominate the compound profile at approximately 75.6% of 168 identified bioactive molecules, with major representatives including ursolic acid, stearoyl glucoside of ursolic acid, alisol A, and euphane-type compounds. Flavonoids account for approximately 14.3% of identified compounds, while alkaloids contribute 1.8% in leaf extracts and 2.9% in flower extracts, with additional minor fractions of iridoids (1.2%), tannins, saponins, steroids, coumarins, quinones, and phlobatannins. Total phenolic content, the most precisely quantified parameter, reaches 614.79 ± 1.25 mg GAE/g dry weight in flower extracts and 563.57 ± 2.03 mg GAE/g in leaf extracts; bioavailability of any constituent is entirely unknown as no human pharmacokinetic studies have been conducted, and the presence of hepatotoxic lantadene A and B negates nutritional relevance.
How It Works
Mechanism of Action
Lantana camara's pharmacological activity is primarily driven by triterpenoids—which represent 75.6% of its 168 reported bioactive compounds—particularly ursolic acid derivatives that enhance peripheral glucose uptake and suppress inflammatory signaling cascades including NF-κB-mediated COX-2 and iNOS upregulation. Phenolic compounds and flavonoids (14.3% of identified phytochemicals) donate hydrogen atoms to neutralize reactive oxygen species and chelate transition metals, with flower extract phenolics (614.79 mg GAE/g) demonstrating stronger radical scavenging than leaf extracts (563.57 mg GAE/g dry weight) in DPPH assays. The hepatotoxic lantadene compounds—pentacyclic triterpene acids including lantadene A and B—disrupt bile secretion and hepatocyte membrane integrity in ruminants and potentially in humans, causing cholestatic liver damage and photosensitization through accumulation of phylloerythrin. Alkaloids (1.8–2.9% depending on plant part) and iridoid glycosides (1.2%) contribute to antimicrobial activity by targeting pathogen-specific enzymes (MAPK1, PDF, SUH) and disrupting microbial membrane potential, while tannins and saponins provide astringent and surfactant-mediated wound-healing properties in topical applications.
Clinical Evidence
Clinical investigation of Lantana camara for any therapeutic indication remains at an early and underpowered stage, with no registered randomized controlled trials identified in major clinical databases. The only human data point is an uncontrolled pilot study using 500 mg/kg dry aqueous leaf extract capsules for anti-haemorrhoidal activity, in which sample size, randomization, blinding status, primary endpoints, and statistical outcomes were not reported in accessible literature. Preclinical rodent studies documenting antidiabetic glucose reduction and anti-inflammatory effects provide mechanistic hypotheses but cannot be directly translated to human dosing or expected effect magnitudes. Given the documented hepatotoxic potential of lantadene compounds and the complete absence of phase I pharmacokinetic safety data in humans, confidence in any clinical application is very low and the risk-benefit ratio does not currently support therapeutic use.
Safety & Interactions
Lantana camara is hepatotoxic and must not be consumed internally; lantadene A, lantadene B, and related pentacyclic triterpene acids cause cholestatic liver damage by impairing bile flow and inducing hepatocyte necrosis, a toxicosis well documented in livestock (cattle, sheep, goats) and plausibly extrapolatable to humans based on the shared mechanism of phylloerythrin accumulation leading to photosensitization, gastroenteritis, and icterus. Green unripe berries are acutely toxic in children and have been associated with fatalities in pediatric case reports, presenting with vomiting, diarrhea, mydriasis, weakness, and respiratory distress, making any formulation involving the whole plant or berry fraction an absolute contraindication in pediatric populations. Potential pharmacokinetic and pharmacodynamic drug interactions include additive hypoglycemic effects with antidiabetic medications (insulin, sulfonylureas, metformin) due to ursolic acid's glucose-lowering activity, and theoretical augmentation of anti-inflammatory drug effects through shared COX-2/5-LOX inhibition; concurrent hepatotoxic drug use (acetaminophen, statins, azole antifungals) poses compounded liver damage risk. Contraindications include pregnancy (uterotonic alkaloid concerns), lactation, pre-existing hepatic or renal disease, and concurrent photosensitizing medication use; no maximum safe dose for humans has been established, and the risk-benefit assessment does not support any internal therapeutic use in current medical practice.

Frequently Asked Questions
Is Lantana camara safe to consume or use as a supplement?
Lantana camara is not safe for internal consumption; it contains hepatotoxic pentacyclic triterpene acids called lantadenes (lantadene A and B) that impair bile secretion and cause cholestatic liver damage. Green berries have been associated with fatal poisonings in children, and no regulatory body has approved any Lantana camara product as a supplement. Internal use is contraindicated, particularly in children, pregnant women, and individuals with liver disease.
What is lantadene and why is it dangerous?
Lantadene refers to a group of pentacyclic triterpene acid compounds—primarily lantadene A and lantadene B—found in all parts of Lantana camara, with highest concentrations in unripe green berries and leaves. These compounds disrupt bile canalicular transport in the liver, causing intrahepatic cholestasis, accumulation of the chlorophyll metabolite phylloerythrin in circulation, and subsequent photosensitization of exposed skin. In ruminant livestock, lantadene toxicosis is a well-characterized veterinary emergency, and the same mechanism applies to humans exposed to sufficient quantities.
What are the traditional uses of Lantana camara in Cambodia and Thailand?
In Cambodian and Thai traditional medicine, Lantana camara is primarily used externally as a leaf poultice applied to rheumatic joints, skin infections, wounds, and eczematous lesions. Internally, leaf decoctions have historically been consumed as antipyretics for malarial fevers and as treatments for diarrhea, though internal use carries hepatotoxic risk. These uses are empirical and have not been validated through controlled clinical research, and the traditional practices predate the modern characterization of lantadene toxicity.
What bioactive compounds are found in Lantana camara leaves and flowers?
Lantana camara leaves and flowers contain a complex phytochemical mixture dominated by triterpenoids (75.6% of 168 identified compounds, including ursolic acid derivatives), with flavonoids comprising 14.3%, alkaloids at 1.8–2.9% depending on plant part, and minor fractions of iridoids, tannins, saponins, steroids, and coumarins. Flower extracts have a particularly high total phenolic content of 614.79 ± 1.25 mg GAE/g dry weight, surpassing leaf extract values. GC-MS analysis also identifies specific volatiles such as loliolide, phytol, and eicosapentaenoic acid contributing to antimicrobial and anti-inflammatory activity in laboratory assays.
Is there any clinical trial evidence for Lantana camara's medicinal benefits?
Clinical trial evidence for Lantana camara is extremely limited; only a single uncontrolled human study has been reported, which evaluated dry aqueous leaf extract capsules (500 mg/kg body weight plus 100 mg/kg lactose) for anti-haemorrhoidal activity in an unspecified number of patients. This study lacked a control group, blinding, reported sample size, and statistical outcome data, making it insufficient to support any therapeutic claim. All other evidence of antidiabetic, anti-inflammatory, and antimicrobial activity comes from preclinical in vitro assays and rodent models, which have not been translated into validated human clinical protocols.
Does Lantana camara interact with NSAIDs or other anti-inflammatory medications?
Since Lantana camara leaf and flower extracts inhibit COX-2 and other inflammatory pathways similar to NSAIDs, concurrent use may increase the risk of additive effects or adverse gastrointestinal outcomes. There are no published clinical studies evaluating specific drug interactions with NSAIDs, corticosteroids, or immunosuppressants, so medical consultation is strongly advised before combining Lantana camara supplements with anti-inflammatory medications. Patients taking prescription anti-inflammatory drugs should inform their healthcare provider before using Lantana camara products.
Is Lantana camara safe during pregnancy and breastfeeding?
No clinical safety data exists for Lantana camara use during pregnancy or lactation, and some traditional preparation methods may concentrate potentially hepatotoxic compounds like lantadenes. Pregnant and breastfeeding women should avoid Lantana camara supplements due to insufficient safety evidence and the plant's known liver toxicity concerns. Consultation with a healthcare provider is essential before considering any Lantana camara product if pregnant or nursing.
What form of Lantana camara extract has the highest antioxidant content—leaf versus flower?
Lantana camara flower extracts have been documented to contain higher total phenolic content and greater antioxidant capacity in laboratory assays compared to leaf extracts from the same plant. However, leaf extracts contain more ursolic acid derivatives and demonstrate superior anti-inflammatory activity in preclinical models. The choice between flower and leaf forms depends on whether the primary desired benefit is antioxidant activity (flowers) or anti-inflammatory effects (leaves), though human efficacy data for either form remains limited.
