Methanolic and infusion extracts inhibit relevant metabolic enzymes and show selective cytotoxicity against hepatocellular carcinoma cell lines in vitro, with GC-MS identification of 84 bioactive compounds in the methanolic extract underpinning these multi-target effects.
Origin & History
Natural habitat
Alchornea cordifolia is a shrub or small tree native to tropical and subtropical Africa, distributed widely across West, Central, and East Africa, including Ghana, Nigeria, Cameroon, and the Democratic Republic of Congo. It thrives in humid forest margins, riverbanks, savanna woodland edges, and disturbed secondary vegetation, tolerating a range of soil types at low to mid elevations. The plant is not formally cultivated commercially but is harvested from wild stands; leaves and fruits are gathered by traditional healers throughout the year, with leaves being the primary plant part used medicinally by the Akan people of Ghana.
“Among the Akan people of Ghana, Alchornea cordifolia—called Odanwoma—has been a cornerstone wound-healing and analgesic plant in traditional medicine for generations, with healers applying leaf decoctions directly to wounds and abscesses and administering oral preparations for fever, pain, and inflammatory conditions. Across West and Central Africa, the plant appears in ethnobotanical records under diverse local names in Yoruba, Igbo, and Hausa traditions in Nigeria, where it is used for malaria, sexually transmitted infections, rheumatism, and liver complaints, reflecting its broad pharmacological reputation. Traditional preparations typically involve pounding fresh leaves into poultices for topical application or boiling leaves and bark to produce decoctions consumed as teas, sometimes combined with other medicinal plants in composite formulations. The plant's prominence across multiple independent African ethnomedicinal systems—without cross-cultural diffusion as the primary driver—has been interpreted by ethnopharmacologists as corroborative evidence for genuine biological activity warranting systematic scientific investigation.”Traditional Medicine
Scientific Research
The evidence base for Alchornea cordifolia consists entirely of in vitro assays and animal studies; no peer-reviewed randomized controlled trials in human subjects have been published as of the most recent literature review. Preclinical anti-inflammatory studies in rats demonstrated 87.69% oedema reduction with methanolic extract at 50 mg/kg, and hepatoprotective studies used Wistar rat models with quantified ALT/AST reductions of 40–45% at doses of 200–800 mg/kg aqueous extract. Antioxidant and cytotoxic properties have been characterized by DPPH/ABTS assays and GC-MS profiling identifying 84 compounds, with antimalarial IC50 values reported against P. falciparum 3D7, though no clinical translation of these findings has been accomplished. Overall, the evidence is preliminary and preclinical in nature; study sample sizes are not systematically reported, methodological standardization is inconsistent across publications, and human bioavailability, pharmacokinetics, and efficacy data are entirely absent.
Preparation & Dosage
Traditional preparation
**Leaf Decoction (Traditional)**
Dried or fresh leaves boiled in water and consumed orally or applied topically; volume and frequency not standardized but widely practiced by Akan healers for wound washing and internal fever/pain management.
**Aqueous Extract (Research)**
200–800 mg/kg used in rat hepatoprotective studies; no human equivalent dose established—these values are not directly translatable to human supplementation
**Methanolic Extract (Research)**
50 mg/kg used for anti-inflammatory endpoints in rodents; total phenolic content standardized to 120–213 mg GAE/g in research preparations, but no commercial standardized product exists
**Fruit Aqueous Extract (Research)**
Used in antimalarial studies at concentrations achieving IC50 4.9 µg/mL in vitro; preparation involves maceration or boiling of dried fruits in distilled water.
**Ethanol Leaf Extract (Research)**
Employed in antimicrobial MIC assays; ethanol concentration and extraction ratio vary by laboratory protocol.
**Standardization Note**
No commercial dietary supplement with defined standardization to any specific marker compound (e.g., quercetin, alchorneine) is currently available; all dosing data are strictly experimental.
Nutritional Profile
Leaves contain high concentrations of polyphenols (total phenolics 120.38–213.12 mg GAE/g in dry extract), flavonoids (9.66–57.18 mg RE/g), condensed tannins (0.55–1.50 mg EC/g), and anthocyanins (up to 5.53 mg C3GE/g in mature leaves). Identified individual phytochemicals include quercetin, quercetin arabinoside, gallic acid, protocatechuic acid, ellagic acid, rutin, myricetin, vitexin, quercitrin, kaempferol, naringenin, shikimic acid, and stigmasterol. Alkaloids present include yohimbine, alchorneine, and triisopentenyl guanidine, which contribute to the plant's unique pharmacological profile beyond polyphenol activity. Fruits yield essential oils containing methyl salicylate (25.3%) and citronellol (21.4%); macro- and micronutrient profiling (proteins, minerals, vitamins) has not been comprehensively published, and bioavailability of key polyphenols from food or extract matrices has not been determined in human studies.
How It Works
Mechanism of Action
Polyphenolic compounds—particularly quercetin, gallic acid, ellagic acid, and rutin—donate hydrogen atoms and electrons to neutralize DPPH and ABTS free radicals in a concentration-dependent manner, interrupting lipid peroxidation chain reactions and reducing cellular oxidative burden. The anti-inflammatory effect is attributed to tannin and terpenoid fractions that likely inhibit cyclooxygenase and lipoxygenase pathways, suppressing prostaglandin and leukotriene synthesis and thereby reducing vascular permeability and oedema formation. Alkaloids including alchorneine and triisopentenyl guanidine may interact with adrenergic and imidazoline receptor subtypes, which could partly explain antinociceptive and cardiovascular effects observed in ethnopharmacological contexts. Antimalarial activity of the fruit aqueous extract likely involves disruption of haemozoin crystallization or interference with the parasite's antioxidant defences, while antimicrobial activity is attributed to phenolic compounds destabilizing bacterial cell membranes and inhibiting key biosynthetic enzymes.
Clinical Evidence
No human clinical trials investigating Alchornea cordifolia for any indication have been identified in the available literature. All efficacy data derive from in vitro cell-based assays and uncontrolled animal experiments, with the strongest preclinical signals in anti-inflammatory, antimalarial, and hepatoprotective endpoints. Effect sizes reported in animal models—such as 87.69% oedema reduction and 40–45% transaminase normalization—are pharmacologically notable but cannot be extrapolated to human therapeutic doses or outcomes without clinical validation. Confidence in clinical benefit is therefore very low, and the compound should be regarded as a candidate for future Phase I/II investigation rather than an evidence-based therapeutic agent.
Safety & Interactions
Acute oral toxicity studies in rodents report an LD50 of 1131.4 mg/kg for aqueous leaf extract, classifying it as relatively low acute toxicity under standard Lorke criteria, though these data do not establish human safety thresholds. No specific adverse effects have been systematically documented in available preclinical literature; aqueous extract administered alone did not significantly alter liver transaminase levels in experimental animals, suggesting a reasonable short-term hepatic safety margin at tested doses. A notable pharmacodynamic interaction has been observed: aqueous extract at 800 mg/kg significantly attenuated isoniazid/rifampicin-induced hepatotoxicity, suggesting potential for interaction with antitubercular drugs and, by extension, other hepatically metabolized medications that warrant caution. Cytotoxic activity identified against hepatocellular carcinoma cells in vitro raises theoretical concerns about effects on normal proliferating cells at high doses; pregnancy and lactation safety has not been evaluated, and use in these populations cannot be recommended without clinical data.

Frequently Asked Questions
What is Odanwoma used for in traditional African medicine?
In Akan traditional medicine in Ghana, Odanwoma (Alchornea cordifolia) is primarily used for wound healing and pain relief, with leaves applied as poultices or decoctions to abscesses and infected wounds. Across West and Central Africa more broadly, it is also used for malaria, fever, liver complaints, rheumatism, and sexually transmitted infections, reflecting a wide ethnopharmacological reputation supported by its diverse phytochemical content including polyphenols, tannins, and alkaloids.
Does Alchornea cordifolia have anti-inflammatory effects backed by research?
Yes, but only in preclinical animal studies; no human clinical trials exist. A methanolic leaf extract administered at 50 mg/kg reduced carrageenan-induced paw oedema by 87.69% in rats, and isolated terpenoid/tannin fractions at 100 mg/kg produced comparable results, likely through inhibition of cyclooxygenase and lipoxygenase pathways. These findings are pharmacologically meaningful but cannot yet be translated into human dosing recommendations without controlled clinical trials.
Is Alchornea cordifolia safe to consume?
Preclinical acute toxicity data indicate an LD50 of 1131.4 mg/kg for the aqueous extract in rodents, suggesting relatively low acute toxicity, and the extract did not alter liver enzymes when given alone in animal studies. However, no human safety trials have been conducted, cytotoxic effects have been observed against cancer cell lines in vitro, and drug interactions with antitubercular medications (isoniazid, rifampicin) and potentially other hepatically metabolized drugs are pharmacologically plausible. Use during pregnancy or lactation is not supported by any safety data.
What are the main active compounds in Alchornea cordifolia?
The primary bioactive compounds include polyphenols such as quercetin, gallic acid, ellagic acid, rutin, myricetin, kaempferol, and naringenin, alongside condensed tannins and anthocyanins in leaves, and fruit essential oils rich in methyl salicylate (25.3%) and citronellol (21.4%). Unique alkaloids including alchorneine, yohimbine, and triisopentenyl guanidine distinguish the plant pharmacologically from purely polyphenol-based botanicals and may contribute to its analgesic and autonomic effects. GC-MS analysis of the methanolic extract has identified up to 84 distinct compounds in total.
What dose of Alchornea cordifolia extract is effective?
No standardized human dose has been established because all efficacy data come from animal experiments. Research protocols have used 50–100 mg/kg methanolic extract for anti-inflammatory endpoints and 200–800 mg/kg aqueous extract for hepatoprotection in rats, but these values cannot be directly converted to human doses using simple allometric scaling without pharmacokinetic data. No commercial standardized supplement exists, and self-dosing is not supported by clinical evidence.
How does Alchornea cordifolia compare to other traditional African herbs for wound healing?
Alchornea cordifolia is distinguished by its documented antimicrobial activity supporting traditional topical wound management, though direct comparative efficacy studies with other African wound-healing herbs remain limited. Its polyphenol-rich composition provides both antimicrobial and anti-inflammatory benefits, making it complementary to herbs like Securidaca longepedunculata or Bridelia ferruginea. The herb's mechanism combines infection prevention with inflammatory suppression, addressing multiple aspects of wound recovery.
Which form of Alchornea cordifolia extract—leaf, methanolic extract, or isolated fractions—provides the strongest anti-inflammatory effect?
Methanolic leaf extract and isolated terpenoid/tannin fractions demonstrate the most robust anti-inflammatory activity in research models, reducing experimental edema by up to 87.69% in animal studies. Isolated polyphenol fractions specifically target pro-inflammatory mediator production and oxidative pathways more selectively than whole-leaf preparations. However, whole-leaf forms may offer broader phytochemical synergy, and direct head-to-head bioavailability comparisons in humans are currently lacking.
What does current clinical research reveal about the strength of evidence for Alchornea cordifolia's health benefits?
Most evidence supporting Alchornea cordifolia comes from in vitro and animal model studies, with methanolic extracts showing significant anti-inflammatory and antimicrobial activity in controlled settings. Human clinical trials remain sparse, limiting definitive conclusions about therapeutic efficacy and optimal dosing in real-world applications. Traditional use in Akan medicine provides ethnomedical validation, but rigorous randomized controlled trials are needed to establish clinical-grade evidence for supplement applications.
