The Short Answer
Derris elliptica roots contain rotenone and related isoflavonoids (deguelin, elliptone, tephrosin) that inhibit mitochondrial Complex I of the electron transport chain, disrupting ATP synthesis in target organisms. Preclinical evidence is limited to insect bioassays and a single rat study where methanolic leaf extract at 400 mg/kg reduced blood glucose from 44.02 to 16.83 mmol/L, comparable to glibenclamide, though no human clinical data exist.

Health Benefits
**Antiparasitic and Pesticidal Activity**
Rotenone and deguelin in the root extract achieve larvicidal LC50 of 1,600 ppm and LC90 of 2,040 ppm against Aedes aegypti larvae, with 100% mortality at highest concentrations after 24 hours, supporting traditional use as a natural parasite-control agent.
**Potential Antidiabetic Effects**
Methanolic leaf extract (DEME) at 200–400 mg/kg reduced fasting blood glucose in diabetic Sprague-Dawley rats from 44.02 ± 5.19 to 16.83 ± 3.14 mmol/L, suggesting glucose-lowering properties though mechanisms remain incompletely characterized.
**Hepatoprotective Indicators**
The same preclinical rat study demonstrated normalization of liver enzymes, with ALT reduced to 61.17 ± 6.9 U/L in treated animals, indicating a potential protective effect on hepatic tissue under metabolic stress conditions.
**Antioxidant Properties**
Flavonoids isolated from Derris elliptica, including apigenin, luteolin, and formononetin, exhibit antioxidant activity in vitro comparable to ascorbic acid and butylated hydroxytoluene (BHT), suggesting free-radical scavenging capacity in leaf and root fractions.
**Natural Piscicide and Traditional Aquatic Parasite Control**: Crushed root extracts applied at 10 g/L have been used in Micronesian and Southeast Asian traditions to stun or kill fish and aquatic parasites, with 90% documented efficacy against brown planthoppers in agricultural settings.
**Protease Inhibition**
An isolated alkaloid from methanol root extracts, characterized by tertiary amine C-N groups (IR: 1300–1476 cm⁻¹), demonstrated 100% mortality against Scotinophara coartata at 0.1% concentration via protease inhibitory activity, suggesting a distinct non-rotenone mechanism.
**Anti-inflammatory Potential**
Phenolic compounds including formononetin and luteolin present in the root and leaf are recognized in broader botanical literature as modulators of pro-inflammatory pathways, though no Derris-specific anti-inflammatory trials have been conducted.
Origin & History
Natural habitat
Derris elliptica is native to Southeast Asia and the Pacific Islands, with a distribution spanning Malaysia, Indonesia, the Philippines, and Micronesia, where it thrives in tropical lowland forests and riverbanks with high humidity. The woody climbing legume is traditionally cultivated or wild-harvested, with its roots prized for their exceptionally high rotenone content, which varies by soil composition and growing conditions. Pacific Island communities, particularly in Micronesia and Melanesia, have historically integrated the plant into subsistence practices along waterways and agricultural plots.
“Derris elliptica has occupied a prominent place in the traditional ecological knowledge of Micronesian, Melanesian, and Southeast Asian communities for centuries, where the root—commonly called 'tuba' in Filipino and Pacific Island traditions—was crushed and introduced into rivers and tidal pools to temporarily stun fish, enabling easy collection without nets or traps, a practice documented across the Pacific and maritime Southeast Asia. The plant's potency as a piscicide and insecticide was recognized long before formal chemical characterization, and Dutch and British colonial botanists in the 19th and early 20th centuries catalogued its use across Java, Borneo, and the Philippines, eventually leading to rotenone's industrial development as a 'natural' insecticide and acaricide in Western agriculture. Medicinal uses, including topical application for skin parasites and ectoparasite control in livestock, are noted in regional ethnobotanical surveys from Micronesia and Borneo, though these applications remain poorly documented and have not been systematically studied. The plant's dual identity as both a traditional community resource and an agricultural chemical precursor reflects the complex boundary between ethnobotanical heritage and industrial exploitation that characterizes many Pacific Island plant species.”Traditional Medicine
Scientific Research
The available body of research on Derris elliptica is exclusively preclinical, comprising in vitro pesticidal bioassays, insect field trials, and a single animal pharmacology study; no human clinical trials, randomized controlled trials, or systematic reviews have been published. Larvicidal studies document quantified LC50 (1,600 ppm) and LC90 (2,040 ppm) values for methanolic root extract against Aedes aegypti, with statistically measurable mortality gradients across concentration ranges, though sample sizes for insect cohorts are typically not reported in standard epidemiological terms. The sole mammalian study used streptozotocin-induced diabetic Sprague-Dawley rats and reported statistically significant glucose reduction at 400 mg/kg (p<0.05 vs. diabetic controls), but the study lacked blinding details, power calculations, and long-term follow-up, substantially limiting interpretive confidence. Overall, the evidence base is rated preliminary, sufficient to justify further mechanistic and safety research but wholly insufficient to support human therapeutic recommendations.

Nutritional Profile
Derris elliptica is not characterized as a food or nutritional source, and no established macronutrient or micronutrient profile exists in the scientific literature. The root's bioactive constituents are dominated by isoflavonoid rotenoids: rotenone (the most abundant, comprising up to several percent of dry root weight in high-yield varieties), deguelin, elliptone, toxicarol, tephrosin, and sumatrol. Secondary phytochemicals include flavones (apigenin, luteolin), an isoflavone (formononetin), and cumaronchromone derivatives (6,4'-dihydroxy-7,5-dimethoxy and 7,4'-dihydroxy-5'-methoxy variants), as well as alkaloids isolated from methanol fractions. Bioavailability data for any of these compounds in human digestive physiology are entirely absent, and given rotenone's known toxicity profile, the root is not considered a source of beneficial nutritional phytochemicals for human dietary intake.
How It Works
Mechanism of Action
Rotenone, the dominant isoflavonoid in Derris elliptica roots, acts as a high-affinity inhibitor of NADH-ubiquinone oxidoreductase (Complex I) in the mitochondrial electron transport chain, blocking electron transfer and thereby suppressing ATP synthesis, leading to cellular energy depletion and death in susceptible organisms including insects, larvae, and fish. Deguelin and tephrosin function through structurally analogous mechanisms, reinforcing Complex I inhibition and potentially contributing to downstream reactive oxygen species (ROS) generation that amplifies cytotoxic effects. A separately isolated alkaloid fraction exerts protease inhibitory activity, interfering with digestive enzyme function in target insects, representing a mechanistically distinct pathway from rotenone's mitochondrial action. In the antidiabetic preclinical context, the methanolic leaf extract's glucose-lowering and liver enzyme normalization effects suggest possible modulation of hepatic gluconeogenesis or pancreatic insulin secretion, though the specific molecular targets—such as alpha-glucosidase, GLUT transporters, or PPAR-gamma—have not been formally identified in published studies.
Clinical Evidence
No human clinical trials have been conducted on Derris elliptica for any indication, including its traditional use in parasite control or any explored medicinal application such as diabetes management. The most structured preclinical data comes from a rat model of streptozotocin-induced diabetes in which methanolic leaf extract at 200–400 mg/kg produced dose-dependent blood glucose reduction (best result: 16.83 ± 3.14 mmol/L vs. 44.02 ± 5.19 in diabetic controls) and ALT normalization (61.17 ± 6.9 U/L), with outcomes statistically comparable to the reference drug glibenclamide. Effect sizes (Cohen's d) were not reported, and the study's methodological limitations—including unspecified sample sizes, absence of pharmacokinetic data, and single-laboratory origin—severely constrain translational confidence. Insect and larvicidal trials provide reproducible quantitative endpoints but are not relevant to human health outcomes, leaving the clinical evidence landscape for Derris elliptica essentially undeveloped.
Safety & Interactions
Rotenone, the principal bioactive compound in Derris elliptica, is a well-documented neurotoxin in animal models associated with Parkinson's disease-like dopaminergic neurodegeneration in the substantia nigra; systemic exposure in humans carries serious neurotoxicity risk, and the compound has been restricted or banned in multiple jurisdictions as a pesticide due to environmental and mammalian toxicity concerns. No specific drug interaction data exist for Derris elliptica extracts in humans, but rotenone's mechanism as a mitochondrial Complex I inhibitor suggests theoretical additive toxicity with other mitochondria-affecting agents including metformin, statins, and certain antiretrovirals. Derris elliptica root preparations are contraindicated for internal human consumption in any form; the plant is not safe for use during pregnancy or lactation given its potent cellular toxicity, and no maximum safe dose for human medicinal use has been established. The preclinical rat antidiabetic study reported no overt hepatotoxicity at tested doses and showed enzyme normalization, but this single study using leaf extract cannot be extrapolated to root preparations or to human safety conclusions.

Frequently Asked Questions
What is Derris elliptica root traditionally used for in Micronesia?
In Micronesian and broader Pacific Island traditions, Derris elliptica root—called 'tuba'—was crushed and introduced into waterways to stun or kill fish, enabling communal harvesting without nets, and was also applied to control ectoparasites on livestock and agricultural pests. The root contains rotenone and related rotenoids that disrupt mitochondrial energy production in fish and insects. This traditional piscicide and insecticide use, rather than direct internal medicinal application, constitutes the primary documented historical role of the plant in Pacific communities.
Is Derris elliptica safe for human consumption or internal use?
Derris elliptica root is not safe for human internal consumption; its primary bioactive compound, rotenone, is a potent neurotoxin that has been used to model Parkinson's disease in laboratory animals by inducing dopaminergic neurodegeneration. No safe human dose has ever been established, and rotenone is classified as a restricted pesticide in multiple countries due to mammalian toxicity. Internal use is contraindicated, and the plant should not be consumed in any medicinal or dietary supplement context without extensive further safety research.
Does Derris elliptica have any proven health benefits backed by clinical trials?
No human clinical trials have been conducted on Derris elliptica for any health application. The only mammalian pharmacology data comes from a single preclinical rat study where methanolic leaf extract at 400 mg/kg reduced blood glucose from 44.02 to 16.83 mmol/L in streptozotocin-diabetic rats, suggesting antidiabetic potential, but this evidence is insufficient to establish clinical efficacy or safety in humans. All other studies have been conducted in insects, larvae, or in vitro systems, making it premature to claim proven health benefits.
What are the main bioactive compounds in Derris elliptica root?
The root of Derris elliptica is richest in isoflavonoid rotenoids, with rotenone as the dominant and most biologically active compound, accompanied by deguelin, elliptone, toxicarol, tephrosin, and sumatrol. Additional phytochemicals include flavones such as apigenin and luteolin, the isoflavone formononetin, cumaronchromone derivatives, and alkaloids extractable via methanol fractionation. Rotenone is the compound responsible for the plant's potent insecticidal and piscicidal properties through inhibition of mitochondrial Complex I.
How does rotenone in Derris root work as a natural insecticide?
Rotenone binds with high affinity to the NADH-ubiquinone oxidoreductase complex (Complex I) of the mitochondrial electron transport chain, preventing electron transfer from NADH to ubiquinone and thereby halting ATP production in affected cells. This energy depletion is particularly lethal to small organisms with high metabolic rates, such as insects and fish, and explains the dose-dependent mortality observed in bioassays—including 100% larval mortality at the highest tested concentrations against Aedes aegypti. The compound's selectivity is relative rather than absolute, as it also affects mammalian mitochondria, which is the basis of its neurotoxic risk in humans and larger animals.
Is Derris elliptica safe during pregnancy and breastfeeding?
Derris elliptica root should be avoided during pregnancy and breastfeeding due to its potent rotenone and deguelin content, which are known neurotoxic compounds that may cross the placental barrier and enter breast milk. Traditional use in Micronesia does not establish safety for vulnerable populations, and no clinical safety studies have evaluated fetal or infant exposure to Derris extracts. Pregnant and nursing women should consult a healthcare provider before any use.
Can Derris elliptica interact with diabetes medications or other drugs?
Derris elliptica may interact with antidiabetic medications, as methanolic extracts have shown blood glucose-lowering effects in animal studies, potentially creating an additive hypoglycemic effect when combined with insulin or oral diabetes drugs. Rotenone in Derris root is also metabolized hepatically and may inhibit or induce cytochrome P450 enzymes, potentially affecting metabolism of other medications. Any concurrent use with pharmaceutical medications requires medical supervision and dose adjustment.
What is the difference between Derris root extract and whole root powder for parasite control?
Derris root extract (typically methanolic or ethanolic) concentrates rotenone and deguelin to achieve higher bioactive compound density, demonstrating superior larvicidal activity (100% mortality at high concentrations within 24 hours) compared to whole root powder, which contains lower relative concentrations of active alkaloids. Extract formulations allow for more precise dosing and faster onset of action against parasites, while whole root powder may be less processed but requires higher quantities for equivalent effect. The choice depends on intended use (internal vs. topical) and local regulatory status, as extracts are more commonly studied and standardized.
