Morinda Lucida
Morinda lucida
Traitement du paludisme dans la médecine traditionnelle ouest-africaine
Morinda lucida contains anthraquinones, including rubiadin and lucidin, which demonstrate antiplasmodial activity against Plasmodium falciparum. These compounds appear to interfere with the malaria parasite's lifecycle, though the precise molecular mechanism requires further research. Laboratory studies confirm these antimalarial properties, supporting centuries of traditional use across West Africa. The plant's hepatoprotective compounds may also support liver function during infection recovery (Evidence Level C).
Can Morinda lucida interact with prescription medications?
Morinda lucida may interact with antidiabetic medications, potentially enhancing blood sugar-lowering effects and causing hypoglycemia. Due to its hepatotoxic potential with prolonged use, concurrent use with other liver-affecting medications, including acetaminophen and alcohol, should be avoided. Those taking prescription antimalarials should consult a healthcare provider before combining treatments. Always disclose all herbal supplements to your healthcare provider (Evidence Level C, Traditional).
What is the recommended dosage for Morinda lucida?
Traditional adult dosages include 5-10 grams of dried leaf prepared as a decoction, taken once or twice daily. Standardized extracts are typically dosed at approximately 300mg twice daily. Treatment duration should be limited due to hepatotoxicity concerns with long-term use. Dosage recommendations are based on traditional use and limited clinical evidence (Evidence Level C). Consult a qualified herbalist or healthcare provider for personalized guidance.
Is Morinda lucida safe during pregnancy and breastfeeding?
Morinda lucida is considered unsafe during pregnancy and should be strictly avoided. The anthraquinone compounds may stimulate uterine contractions or affect fetal development. Safety during breastfeeding has not been established, so nursing mothers should also avoid this herb. Women of childbearing age should use reliable contraception while taking Morinda lucida. Always consult a healthcare provider before using any herbal supplement during pregnancy (Evidence Level C, Traditional).
What are the side effects of Morinda lucida?
Common side effects include gastrointestinal disturbances such as nausea, diarrhea, and abdominal discomfort. The primary safety concern is hepatotoxicity with prolonged or excessive use, which may cause elevated liver enzymes or liver damage. These risks increase with long-term consumption beyond recommended durations. Discontinue use if jaundice, dark urine, or unexplained fatigue occurs. Regular liver function monitoring is advisable during extended use (Evidence Level C, Traditional).
What is Morinda lucida used for in traditional medicine?
Morinda lucida has been used extensively in West African traditional medicine for treating malaria, diabetes, and liver disorders including jaundice. Traditional healers also employ it for fever management and general wellness support. The plant's anthraquinone content provides documented antiplasmodial and potential anti-diabetic properties. While traditional use spans centuries, clinical evidence remains limited (Evidence Level C). Modern research continues to investigate these traditional applications.

Résumé
Morinda lucida, also known as the brimstone tree, is an ethnomedicinal plant widely used in traditional African medicine for treating malaria, inflammation, and various fevers [PMID:33753141].
Contexte
Morinda lucida Benth belongs to the Rubiaceae family and is commonly referred to as the brimstone tree [PMID:33753141]. It is an indigenous plant used particularly in the African continent, with various parts including the stem bark, leaves, and roots utilized for medicinal purposes [PMID:33753141, PMID:20162091].
Usages traditionnels
Traditionally used in Africa for the management of malaria, diabetes, hypertension, inflammation, typhoid fever, cancer, cognitive disorders, sickle cell disease, trypanosomiasis, onchocerciasis, and various fevers [PMID:33753141]. It is specifically used in Southwest Nigeria for malaria treatment [PMID:35531230, PMID:20162091] and in Benin as a popular folk medicine [PMID:36986917].
Composés actifs
Phytochemical analysis of leaf and bark extracts has revealed the presence of tannins, alkaloids, steroids, saponins, phenols, and flavonoids [PMID:35531230]. Other identified compounds include iridoids (such as ML2-2 and the tetracyclic iridoid ML-2-3), phytosterols, and triterpenes [PMID:36914035, PMID:35414765, PMID:30771146].
Mécanisme d'action
Anti-inflammatory and analgesic effects are mediated via agonism at kappa and delta opioid receptors, inhibition of COX-2, and elevation of CAT and SOD activities [PMID:36914035]. Leaf extracts may reduce nitric oxide and prostaglandin E-2 levels by affecting inducible nitric oxide synthase expression [PMID:34012871].
Preuves cliniques
Preuve DMalaria
Leaf and bark extracts showed antiplasmodial activity in mice [PMID:35531230] and schizontocidal activity in P. berghei infections [PMID:2994441]. In vitro studies showed sensitivity of P. falciparum isolates to M. lucida [PMID:24555525].
Preuve DInflammation/Pain
Hydroethanolic leaf extract showed activity against localized and systemic inflammation in rats [PMID:34012871]; iridoids from the plant exhibited analgesic and anti-inflammatory activities [PMID:36914035].
Preuve DFever
Aqueous extracts of leaves produced a significant reduction in rectal temperature in albino rats [PMID:37545963].
Preuve DCognitive Impairment
Ethyl acetate extracts ameliorated scopolamine-induced memory deficits in mice [PMID:28480424].
Preuve DHepatotoxicity (Lead-induced)
Stem bark extract reversed lead nitrate-induced liver injury and improved hepatic histomorphology in Wistar rats [PMID:35691788, PMID:35800154].
Preuve D
Sécurité et effets indésirables
Acute oral toxicity tests in rats indicated the leaf extract is non-lethal at 6400 mg/kg and has no toxic effect on liver and kidney functions [PMID:22574294]. However, long-term administration (13 weeks) of leaf extract in male rats significantly reduced sperm motility, viability, and epididymal sperm counts, and caused damage to seminiferous tubules [PMID:16281089].
Grossesse et allaitement
M. lucida extract reduced the contractility of isolated uterine smooth muscle in both pregnant and non-pregnant mice [PMID:18379632].
Interactions médicamenteuses
A decoction containing M. lucida (MAMA decoction) was found to increase the maximum concentrations of amodiaquine in mice, suggesting a pharmacokinetic herb-drug interaction [PMID:31642009].
Synthèse des preuves
The current evidence is primarily based on in vitro studies and animal models (Level D), with some review articles (Level C). There is a lack of human clinical trials.
