Synopsis

Tridax (Tridax procumbens L.): A Comprehensive Reference

1. Identity and Botanical Description

Nomenclature and Taxonomy

Tridax procumbens L., commonly known as coatbuttons or tridax daisy, is a species of flowering plant in the family Asteraceae. The genus name Tridax refers to the three lobes of the ray flowers, while procumbens refers to the prostrate, trailing habit of the stems. Other species of the genus include T. balbisioides and T. trilobata.

Common names include coatbuttons and tridax daisy in English; cadillo chisaca in Spanish and herbe caille in French; and, among Indo-Aryan languages, jayanti veda (जयंती वेद) or avanti in Sanskrit, and ghajadvu or ghaburi (ઘાબુરી) in Gujarati. Regional names also include "Ghamra" and "Jayanti Veda." In India, it is also known as Dhaman grass.

Geographic Distribution and Habitat

The plant is native to the tropical Americas including Mexico, but has been introduced to tropical, subtropical, and mild temperate regions worldwide. It is listed as a noxious weed in the United States and has pest status in nine states. T. procumbens is an annual or perennial herb, mostly found as a weed of cultivation, grown on waste ground, or as an invader of bare soil.

Morphology

It is a perennial herb with a firm taproot, with a herbaceous, semi-prostrate habit, growing anywhere from 15–40 cm in height. The branches ascend from a creeping base, with a cylindrical stem, often purplish, sparsely and patently long- and white-pubescent. The leaves are elongated, opposite, ovate with serrated margins, hirsute on the abaxial and adaxial sides. The plant has an average height of around 20–60 cm and is branched; leaves are 4–8 cm long, simple, opposite, and stipulate. The inflorescence is around 12–32 cm, oval-shaped and held by a peduncle, with ray florets and disc florets; flowers are daisy-like with yellow-centred white or yellow petals.

Common Preparations and Forms

Different substances such as oils, teas, and skin poultices, among others, have been manufactured using this species. In research and traditional practice, the plant's various parts — leaves, stems, flowers, and roots — are used in different preparations. Concoctions of extracts from T. procumbens leaves, stem, flower, and roots are used to treat patients suffering from diabetes, arthritis, inflammatory reactions, and even applied to open wounds. Modern pharmaceutical research has explored ethanol extracts, aqueous extracts, methanol extracts, essential oils, leaf juices, topical ointments, and nanoparticle-based formulations derived from the plant.

2. Traditional and Historical Use

Ayurvedic and Indian Traditions

Tridax procumbens is native to Central and South America; since ancient times, this species has been used in Ayurveda in India. It is well-known as an Ayurvedic, ethnobotanical, and Unani medicinal plant. It has been employed in Ayurveda, Siddha, and folk practices for the treatment of wounds, liver disorders, skin infections, diarrhoea, fever, and diabetes.

Traditionally, Tridax procumbens has been in use in India for wound healing and as an anticoagulant, antifungal, and insect repellent. In India, it has been used as an anticoagulant, antimicrobial, insect repellent, and wound healing agent, and also to cure boils and blisters. The plant is widely used as a folk medicine for ulcer and as a hair tonic; leaf decoctions were known to treat infectious skin diseases in ethnomedicines; and it is a well-known Ayurvedic medicine for liver disorders, as the plant decoctions are hepatoprotective in nature.

Tribal inhabitants of Udaipur district in Rajasthan (India) traditionally use the leaf powder (along with other herbs) orally to treat diabetes. The whole plant and seeds are reported to be used to treat various ailments, such as bronchial catarrh, dysentery, diarrhoea, preventing hair loss, and to check haemorrhage from cuts.

Central American and Guatemalan Traditions

In Guatemala, T. procumbens is used as a natural antibacterial, antifungal, and antiviral treatment, as well as for vaginitis, stomach discomfort, diarrhoea, mucosal inflammations, and skin infections; the healing and bleeding-stopping properties of the leaf juice are also recognized. The whole plant is used to treat protozoal illnesses in Guatemala, including dysentery, leishmaniasis, and malaria. A study conducted in Chiquimula, Guatemala, showed that lactating pregnant women suffering from anaemia could reduce their symptoms by using Tridax.

Broader Traditional Uses Across Regions

Several reports illustrate the use of different parts of the plant as traditional medicine in India and various tropical, subtropical, and mildly temperate regions worldwide; many of the traditional uses are related to microbial infections, particularly in the treatment of bronchial catarrh, wound healing, and chronic disorders that cause lung infections such as asthma, pneumonia, and influenza. Traditionally, the herb has been used as a hair tonic and to heal wounds, fevers, coughs, and dysentery. The leaf juice is recorded as possessing antiseptic, insecticidal, and parasiticidal properties, as a remedy against conjunctivitis, and for checking haemorrhage from cuts, bruises, and wounds.

3. Key Chemical Constituents

Flavonoids

Flavonoids represent one of the most significant phytochemical groups found in Tridax procumbens; compounds such as quercetin, luteolin, apigenin, and catechins have been reported in various studies. Bioactive components including luteolin, glucoluteolin, quercetin, and isoquercetin have been reported from its flowers. The flavonoid procumbenetin has been isolated from the aerial parts. Ethyl acetate extraction isolates the flavonoids centaureidin and centaurein, as well as bergenin.

Kaempferol is the main flavonoid found in the leaves of T. procumbens. Preclinical studies have shown that kaempferol and its glycosidic derivatives exhibit a wide range of medicinal properties including antioxidant, analgesic, anti-inflammatory, antimicrobial, antifungal, anticancer, cardioprotective, neuroprotective, hepatoprotective, and antidiabetic activities; kaempferol has many beneficial effects on inflammatory diseases by mediating anti-inflammatory or immunomodulatory activities.

Terpenoids and Sterols

Other chemical compounds isolated from the plant include alkyl esters, sterols, pentacyclic triterpenes, fatty acids, and polysaccharides. Literature surveys report the presence of phytochemical compounds including alkaloids, carotenoids, flavonoids, saponins, fumaric acid, β-sitosterol, and tannins; the plant is richly endowed with oleanolic acid, and high contents of sodium and potassium. Phytoconstituents of Tridax procumbens include β-sitosterol, carotenoids, luteolin, and linolenic acid among other active constituents.

Essential Oils

The essential oil of T. procumbens is a good source of natural α-pinene, β-pinene, L-phellandrene, and sabinene, which are responsible for biological effects such as antimicrobial, anti-cancer, anti-inflammatory, and larvicidal activities. The main essential oil constituents found in T. procumbens are (Z)-falcarinol, α-selinene, and zerumbone. The compound (3S)−16,17-dihydrofalcarinol, extracted by supercritical technique, was previously reported to have antileishmanial activity.

Other Secondary Metabolites

The great variety of secondary metabolites present in the plant include tannins, alkaloids, saponins, flavonoids, phenols, steroids, anthocyanins, proteins, amino acids, and carbohydrates, which have been a great source of important pharmaceutical compounds. Among secondary metabolites identified were fumaric acid, sterols, glucoluteolin, isoquercetin, quercetin, and luteolin. The plant contains significant amounts of trace elements including magnesium, phosphorus, potassium, selenium, iron, copper, manganese, sodium, zinc, and calcium.

4. Mechanisms of Action

Antioxidant Activity

Flavonoid compounds such as quercetin, luteolin, apigenin, and catechins are well-known for their potent antioxidant activity, which enables them to neutralize harmful free radicals and prevent oxidative stress-related cellular damage. The antioxidant properties of the plant contribute broadly to its hepatoprotective, anti-inflammatory, and wound-healing pharmacological activities as documented across multiple preclinical investigations.

Immunomodulatory Mechanisms

The immunomodulatory properties of the ethanol-insoluble fraction of the aqueous extract (TPEIF) of T. procumbens have been investigated; after intraperitoneal administration of TPEIF at doses of 0.25 and 0.5 g/kg body weight, a significant increase in phagocytic index, leukocyte count, and splenic antibody-secreting cells was observed; stimulation of humoral immune response was further observed with elevation in haemagglutination antibody titer; heightened delayed-type hypersensitivity reaction suggested convincing evidence for activation of the cellular immune system.

Wound Healing Mechanisms

The aqueous extract formulation has been shown to increase hydroxyproline, hexamine, and collagen turnover in wound healing due to the presence of flavonoids, polyphenols, terpenoids, carbohydrates, tannins, and vitamins essential for wound healing. A serine protease specifically isolated from the plant — termed Procumbenase — has been further characterized as a specific mechanism contributor: a serine protease, Procumbenase (MW 109.73 kDa), has been purified from the aqueous extract of Tridax procumbens; in vivo incision and excision wound healing in rats showed that Procumbenase enhanced the wound healing process; and Procumbenase enhanced skin tensile strength and collagen formation as evidenced by hydroxyproline estimation.

Anti-Inflammatory Mechanisms

Kaempferol, the principal leaf flavonoid, has many beneficial effects on inflammatory diseases by mediating anti-inflammatory or immunomodulatory activities; it inhibits various signalling pathways and suppresses matrix-degrading enzymes. The plant also has immunomodulatory properties, enhancing both humoral and cellular immune responses; extracts have been reported to stimulate antibody production and activate macrophages, thereby strengthening the body's defence mechanisms.

Antidiabetic Mechanisms

Experimental studies indicate that leaf extracts improve blood glucose levels, enhance insulin sensitivity, and normalize lipid profiles, possibly through inhibition of carbohydrate-hydrolysing enzymes and antioxidant effects.

5. Scientific Evidence by Area of Use

Important note on evidence quality: As of the current literature, virtually all pharmacological evidence for T. procumbens derives from in vitro (cell-based) and in vivo (animal) studies. The effectiveness of Tridax procumbens in controlling blood glucose and lowering cardiovascular risk in diabetics has not been studied in clinical studies. Despite its therapeutic potential, challenges remain in terms of standardised formulations, detailed mechanistic studies, and clinical validations. The sections below characterise the nature and strength of the evidence for each area.

5.1 Wound Healing

Wound healing is the most extensively investigated pharmacological application of T. procumbens. Traditionally, the juice from the leaves has been used for healing dermal wounds; however, in experimental studies, equivocal pro- and anti-healing actions of T. procumbens have been demonstrated.

Multiple animal model studies have reported positive outcomes. The whole plant extract (WPE) of Tridax procumbens demonstrated the greatest pro-healing activity as evidenced by increase in tensile strength and lysyl oxidase activity after being studied in a dead-space wound model in albino rats. Studies have evaluated the wound healing activity of ethanolic extract of T. procumbens in streptozotocin-induced diabetic and non-diabetic laboratory animals using ointment base preparations at 2.5% and 5% w/w on diabetic and non-diabetic rats, using incision, excision, and burn wound models. These findings confirmed the ethnomedicinal claim of Tridax procumbens in wound healing in diabetic and non-diabetic conditions.

In vitro studies at concentrations of 3 µg/mL and 5 µg/mL showed significant proliferation and mobilisation of fibroblasts, keratinocytes, and angiogenesis at the site of injury; in vivo studies of aqueous extract formulation showed greater wound contraction than the standard drug Cipladine and control over 15 days. A scratch assay with NIH 3T3 fibroblasts showed Procumbenase's cell proliferation and migratory effects, confirming it as the major bioactive molecule in T. procumbens extract to enhance wound healing activity.

Evidence strength: Leaves aqueous extract, water-soluble bioactive compounds, and inorganic salts of T. procumbens were found effective in wound healing properties; however, scientific reports investigated wound healing activity only on plant extracts, and more specific studies are needed to identify the wound-healing compounds definitively. No controlled human clinical trials on wound healing have been published.

5.2 Antidiabetic and Antihyperlipidaemic Activity

Studies used 50% methanol extraction of the whole plant, and the extract was tested for acute and sub-chronic anti-hyperglycaemic activity in alloxan-induced diabetic rats and for acute toxicity in normal rats. Oral administration of acute and sub-chronic doses of 250 and 500 mg/kg body weight of T. procumbens extract showed a significant (p < 0.05) reduction in fasting blood glucose levels in diabetic rats, but not in normal rats; in the acute study, the maximum percentage blood glucose reduction was 68.26% at 250 mg/kg and 71.03% at 500 mg/kg body weight in diabetic rats, observed at 6 hours.

Preclinical studies have indicated that acute and subacute administration of Tridax procumbens to alloxan-induced diabetic rats reduced fasting glucose levels in blood but not those of control rats; in rats loaded with cholesterol (1 g/100 g body weight), Tridax procumbens also reduced blood levels of total cholesterol, LDL, VLDL, and triglycerides, along with atherogenic index and atherogenic coefficient.

Research has also explored nanoparticle-mediated delivery: anti-diabetic activities of aqueous leaf extract (TPE) and TPE-derived zinc oxide nanoparticles were carried out in a streptozotocin-induced diabetic rat model; TPE and TPE-derived ZnO NPs were administered orally, once every day for 21 days in diabetic rats, at 100 and 200 mg/kg, respectively. At 200 mg/kg/day, TPE-derived ZnO NPs had a more substantial hypoglycaemic response than at 100 mg/kg/day; thus, ZnO NPs biosynthesised from the leaf extract exerted more potent anti-diabetic activity than TPE and glibenclamide in this experimental setting.

Evidence strength: Entirely preclinical (animal model). The effectiveness of Tridax procumbens in controlling blood glucose and lowering cardiovascular risk in diabetics has not been studied in clinical studies; there has been a paucity of evidence concerning the molecular mechanisms that underlie the anti-inflammatory and antihyperglycaemic activities.

5.3 Hepatoprotective Activity

Studies using CCl₄ and paracetamol-induced liver injury models show that extracts of the plant reduce serum liver enzyme levels and restore antioxidant enzyme activities, suggesting protection against hepatotoxicity. In the paracetamol model, paracetamol (2 g/kg body weight)-induced hepatic damage was manifested by significant increases in the activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) in serum and enhanced lipid peroxidation; the activities of superoxide dismutase and catalase in liver tissue were lowered; and serum bilirubin level was increased as a consequence of the induced hepatic injury.

In the D-galactosamine/lipopolysaccharide (D-GalN/LPS) hepatitis model, rats intoxicated with D-GalN/LPS alone developed hepatocellular damage as evident from a significant elevation (p < 0.05) in the serum activities of AST, ALT, ALP, LDH, γ-GT, and bilirubin level. Plant decoctions act as hepatoprotective in nature, representing a well-known Ayurvedic use for liver disorders.

Evidence strength: All hepatoprotective evidence is from animal models. No clinical data in humans are available.

5.4 Anti-Inflammatory and Analgesic Activity

At dosages of 200 and 400 mg/kg, the ethanolic leaf extracts of Tridax procumbens demonstrated substantial anti-inflammatory activity against Irish Moss-triggered inflammation in Wistar rats; after 3 hours, 400 mg/kg showed a significant reduction in inflammation of 48%, with the impact increasing after 3 hours to 52%.

Anti-arthritic activity was assessed in a Freund's Complete Adjuvant (FCA) arthritis model: to determine the anti-arthritic effect of the whole plant ethanolic extract of Tridax procumbens, female Sprague Dawley (SD) rats were used for anti-arthritic screening; arthritis was induced using FCA, and the anti-arthritic effect of the ethanolic extract was studied at doses of 250 and 500 mg/kg; the effects were compared with those of indomethacin (10 mg/kg).

Analysis of anti-inflammatory and antioxidant activity of T. procumbens leaves extract-based chitosan gel was conducted by bovine serum albumin denaturation assay, egg albumin denaturation assay, DPPH assay, and hydroxyl radical scavenging assay; both BSA and EA assays showed that the formulation demonstrated maximum inhibition at 50 µL concentration; the antioxidant activity assays revealed high inhibitory percentage at all tested concentrations.

Evidence strength: Anti-inflammatory evidence is from in vitro assays and animal models only. No human clinical trial data exist.

5.5 Antimicrobial Activity

T. procumbens has been shown to inhibit the growth of Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris, Bacillus subtilis, and Staphylococcus aureus, and it showed possible immunomodulatory properties. Previous research found that T. procumbens extracted with ethanol had antibacterial action, whereas water extract had no antibacterial activity; the difference in antibacterial activity between alcohol and aqueous extracts demonstrated that different solvents extract phytochemicals differently depending on polarity and solubility; antimicrobial characteristics are attributed to the inclusion of flavonoids, alkaloids, saponins, and tannins.

Research into green-synthesised silver nanoparticles (AgNPs) from the plant has extended antimicrobial investigations: the synthesised silver nanoparticles exhibited antimicrobial activity against multidrug-resistant (MDR) clinical isolates including Escherichia coli, Shigella spp., Aeromonas spp., Pseudomonas aeruginosa, and Candida tropicalis, and had anticancer activity against A549 cells (IC₅₀ 42.70 µg/ml).

Evidence strength: In vitro antimicrobial evidence is reasonably consistent across multiple studies. No clinical trials assessing antimicrobial efficacy in humans have been conducted.

5.6 Immunomodulatory Activity

After intraperitoneal administration of the ethanol-insoluble fraction of the aqueous extract (TPEIF) in doses of 0.25 and 0.5 g/kg body weight, a significant increase in phagocytic index, leukocyte count, and splenic antibody-secreting cells was noticed; stimulation of humoral immune response was further observed with elevation in haemagglutination antibody titer; heightened delayed-type hypersensitivity reaction suggested convincing evidence for activation of the cellular immune system; protective action in cases of anaphylactic shock was also studied; and elicitation of specific antibody titer against tetanus toxoid (TT) challenge was measured in order to explore possible use as an adjuvant along with clinical vaccination programmes.

Evidence strength: Animal experiments only. No controlled human data.

5.7 Anticancer Activity

Information related to traditional use of T. procumbens for cancer is not reported; however, recently a few articles have been published on it; scientific reports indicate that potent anticancer agents such as flavonoids, tannins, and saponins are abundantly present in the plant.

One study investigated the chemical composition of the essential oil of leaves of T. procumbens and its in vitro anticancer activity; the hydrodistilled essential oil contains 16 components by GC-MS analysis, and the essential oil was tested against a human breast cancer cell line (MCF-7) for anticancer activity by MTT assay at different concentrations of 18.5–300 µg/ml. The results showed that the essential oil showed concentration-dependent activity against the cell line.

Computational approaches have also been applied: a study aimed to investigate the anti-cancerous activity against human lung cancer by targeting luteolin, a phytochemical of Tridax procumbens; the computational study examined structural properties of luteolin; drug-likeness of the molecule was predicted by virtual screening of ADMET properties; and the molecular docking technique was performed to check the complex formation between protein and ligand.

Evidence strength: Entirely in vitro and in silico (computational). No animal or human studies have established anticancer efficacy. This evidence is preliminary only.

5.8 Antileishmanial Activity

The compound (3S)-16,17-dihydrofalcarinol from T. procumbens was previously reported to have antileishmanial activity. Studies in mouse models using a mixture of T. procumbens and Allium sativum have also been reported in the published literature as showing antileishmanial activity in mice. Both T. procumbens and Allium sativum have shown beneficial effects against parasitic and bacterial diseases; the biological activity of the oxylipin (3S)-16,17-didehydrofalcarinol, isolated from T. procumbens, against the parasite Leishmania mexicana has been verified.

Evidence strength: In vitro and preliminary in vivo animal data only.

5.9 Hair Growth Promotion

The plant is widely used as folk medicine as a hair tonic. Research has proposed the formulation, development, and evaluation of hair gel-cream using Tridax procumbens, with the goal of reducing white hair, reducing fungal infection, and preventing hair loss. Stability parameters of the formulation showed no significant variation during stability studies, with uniform viscosity and less moisture content, and no irritation or redness caused during patch testing.

Evidence strength: The hair growth application is based on traditional use and formulation studies. No controlled clinical evidence is available.

Dermatological (hair and scalp): Traditional use as a hair tonic documented across multiple Indian ethnobotanical records.

7. Dosage Forms and Reported Dosages

No standardised pharmaceutical monograph or regulatory dosage recommendation exists for T. procumbens as a dietary supplement. The following dosages are drawn exclusively from published research studies.

Oral extract (antidiabetic/anti-hyperglycaemic, animal): Acute and sub-chronic doses of 250 mg/kg and 500 mg/kg body weight of 50% methanolic whole-plant extract were administered orally; significant blood glucose reduction was observed at both doses, with the maximum effect at 6 hours.
Oral ZnO nanoparticle preparation (antidiabetic, animal): TPE and TPE-derived ZnO NPs were administered orally, once every day for 21 days in diabetic rats, at 100 and 200 mg/kg respectively; the standard antidiabetic medication glibenclamide was used as a control at a dose of 10 mg/kg.
Topical ointment (wound healing, animal): An ointment formulation of leaf juice (50 mg of either 1 or 4 mg/g) was applied twice daily for 4 days on dermal wounds in mice.
Topical ointment base (wound healing, animal): Simple ointment base at 2.5% and 5% w/w of ethanolic extract was formulated to evaluate wound healing potential on diabetic and non-diabetic rats.
Intraperitoneal (immunomodulatory, animal): After intraperitoneal administration of TPEIF in doses of 0.25 and 0.5 g/kg body weight, significant immune-stimulatory effects were observed.
Oral extract (anti-inflammatory, animal): At dosages of 200 and 400 mg/kg, ethanolic leaf extracts demonstrated substantial anti-inflammatory activity.
Anti-arthritic dosage (animal): The anti-arthritic effect of the ethanolic extract was studied at doses of 250 and 500 mg/kg in FCA-arthritis model rats.
Acute oral toxicity testing range (animal): To determine acute toxicity, different doses of the drug (0.25–5.0 g/kg) were administered to different groups of rats to observe mortality and general behaviour.

8. Safety Considerations

General Toxicological Profile

Toxicological tests have shown that T. procumbens did not show toxicity even at high concentrations, demonstrating a high margin of safety. Test results support the traditional medicinal use of T. procumbens for the treatment of diabetes mellitus with no visible signs or symptoms of toxicity in normal rats at standard doses, indicating a high margin of safety.

Acute Oral Toxicity Studies

No clinical signs of toxicity were observed in any of the animals dosed with T. procumbens and A. sativum extracts in a formal acute oral toxicity study. In none of the animals dosed with T. procumbens, A. sativum, and the mixture was there a difference in the levels of transaminases. However, in the histopathology study, slight lesions were observed in the hepatocytes of the mice treated with T. procumbens at high doses.

There was no difference in the weight index in most of the animals, except for the animals treated with T. procumbens at doses of 2000 mg/kg who presented an increase in the weight index; a direct proportional correlation was also observed between T. procumbens dose and food consumption.

Nanoparticle Safety

Many scientific studies report that Tridax procumbens-based AgNPs elicit significant antibacterial, antioxidant, anticancer, and other pharmacological activities; however, AgNPs are considered a double-edged sword — despite their tremendous implications in health care, they also have cytotoxic, genotoxic, and epigenetic effects on living systems. Histopathological assessment in one study revealed that synthesised TPE-derived ZnO NPs were safe, non-toxic, and biocompatible in the tested animal model.

Absence of Clinical Safety Data

T. procumbens predominantly shows wound healing, antimicrobial, and anti-inflammatory properties as studied in traditional use; however, this is not further supported by the isolation of specific chemical compounds, and a lack of bioassay-guided isolation strategies has been observed. Standardised formulations and dosing recommendations are considered essential for safe therapeutic application. The absence of human clinical trial data means that established safety profiles, drug interaction data, contraindications for specific populations (pregnant or lactating women, children, and those with chronic disease), and long-term safety at supplemental doses cannot be defined from existing sources.

Overall Research Gaps

Further studies on chemical compounds, pharmacological and biological activities of vegetative and reproductive organs of the species are necessary, since they may have the potential to encourage incorporation into future studies. The existing results warrant follow-up through bioassay-directed isolation of the active principles. While modern pharmacological studies have validated many of its traditional claims, demonstrating wound healing, anti-inflammatory, antimicrobial, antioxidant, hepatoprotective, antidiabetic, immunomodulatory, and anticancer properties, challenges remain in terms of standardised formulations, detailed mechanistic studies, and clinical validations.
