# Moringa (genus)
**Moringa** is a genus of flowering plants in the family [Moringaceae](https://www.edgepedia.org/moringaceae), order Brassicales, comprising 13 species of trees and shrubs distributed through southwest Asia, southwest Africa, northeast Africa, and [Madagascar](https://www.edgepedia.org/madagascar).[1](https://www.frontiersin.org/journals/pharmacology/articles/10.3389/fphar.2018.00108/full) It is the only genus of its family, yet it is one of the most phenotypically varied groups of angiosperms for its size, ranging from slender bottle trees to small annual herbs.[2](https://www.formad-environnement.org/Olson2002_Moringa_phylogeny.pdf) The best-known species, *Moringa oleifera*, is cultivated widely across the tropics for food, fodder, medicine, and water treatment.[3](https://feedipedia.review.fao.org/node/124)
| Key fact | Detail |
|---|---|
| Taxonomy | Sole genus of Moringaceae (order Brassicales); 13 recognized species, though some 34 varieties appear in the literature, many unresolved duplicates[1](https://www.frontiersin.org/journals/pharmacology/articles/10.3389/fphar.2018.00108/full) • [4](https://repositum.tuwien.at/bitstream/20.500.12708/10451/2/Tanaskovic%20Vesela%20-%202018%20-%20Making%20Sahara%20desert%20green%20sustainable%20transport%20of...pdf) |
| Name origin | From the Tamil word *murungai*, meaning "twisted pod", referring to the immature fruit[5](https://wjpr.s3.ap-south-1.amazonaws.com/article_issue/e70a1d096a81f311ccdb8da67c2f893f.pdf) |
| Type species range | *M. oleifera* is native from NE. Pakistan to NW. India; first published in 1785[6](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A584736-1) |
| Family divergence | Moringaceae divergence estimated around the Oligocene-Paleocene periods[7](https://pmc.ncbi.nlm.nih.gov/articles/PMC10040795/) |
| Seed oil | *M. oleifera* seeds contain about 30-40% edible ben oil, resistant to rancidity and rich in oleic acid, sterols, and tocopherols[3](https://feedipedia.review.fao.org/node/124) |
| Water treatment | Seed cationic proteins (MOCPs) coagulate colloids and microorganisms in drinking water; 258 articles on moringa and water treatment were published from 1995 to 2019[8](https://www.sciencedirect.com/science/article/pii/S0957582020317626) |
| Clinical evidence | A meta-analysis of 9 randomized trials (649 participants) found no significant cardiometabolic effects, with very low certainty evidence[9](https://pmc.ncbi.nlm.nih.gov/articles/PMC12655524/) |
## Taxonomy and diversity
The genus was described by Adamson (as Moringa Adans.) and sits within the Brassicales, related to [Caricaceae](https://www.edgepedia.org/caricaceae) (papaya) and the cabbage family. Molecular phylogenies recover *Moringa oleifera* and *Carica papaya* as sister clades to a group containing Bataceae, Resedaceae, Capparaceae, Cleomaceae, and [Brassicaceae](https://www.edgepedia.org/brassicaceae).[10](https://pmc.ncbi.nlm.nih.gov/articles/PMC7496422/) A combined DNA and morphology analysis of the family notes that the [Old World](https://www.edgepedia.org/old-world) dry tropical Moringaceae is remarkable for the diversity of habit and floral morphology found within its single genus.[2](https://www.formad-environnement.org/Olson2002_Moringa_phylogeny.pdf) In Pakistan, the genus is represented by only two species.[11](https://efloras.org/florataxon.aspx?flora_id=5&taxon_id=121194)
## Distribution and ecology
*Moringa oleifera* originated from the southern hills of the [Himalayas](https://www.edgepedia.org/himalayas) and was introduced to many tropical and subtropical areas, largely by migrant Asian populations.[3](https://feedipedia.review.fao.org/node/124) Kew's Plants of the World Online lists its native range as NE. Pakistan to NW. India and records introductions across dozens of countries in Africa, Asia, the Caribbean, and the Americas.[6](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A584736-1) The tree is drought-resistant, fast-growing, and produces leaves during the dry season, making it a green vegetable source when little other food is available.[3](https://feedipedia.review.fao.org/node/124) A related species, *Moringa peregrina*, is assessed on the IUCN Red List.[12](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A584740-1/general-information)
## Uses
**Food and fodder.** All parts of *M. oleifera* are consumed as food: leaves, pods, roots, and flowers are cooked as vegetables, immature seeds are cooked, and mature seeds are roasted like peanuts.[3](https://feedipedia.review.fao.org/node/124) The leaves are rich in protein, vitamins A, B, and C, and minerals, and leaf powder is used to aid the recovery of malnourished infants.[3](https://feedipedia.review.fao.org/node/124) In livestock systems, moringa leaves serve as a protein supplement for ruminants, and feeding cattle moringa leaves or seeds significantly decreases ruminal methane emissions.[13](https://www.fao.org/family-farming/detail/en/c/1644586/) Leaf meal is used cautiously in poultry feeds, at no more than 5% of the diet.[3](https://feedipedia.review.fao.org/node/124)
**Water treatment.** Crushed seeds release cationic proteins that neutralize the negative surface charge of colloidal particles and motile microorganisms, allowing them to settle; the approach has been proposed for low-income settings because of low cost, biodegradability, and reduced by-product generation.[8](https://www.sciencedirect.com/science/article/pii/S0957582020317626) Reviews conclude the most viable application is as a flocculation aid, reducing the dose of chemical coagulants, and note that pilot-scale studies remain a research gap.[8](https://www.sciencedirect.com/science/article/pii/S0957582020317626) Seed cake left after oil extraction is used as green manure or a flocculating agent.[3](https://feedipedia.review.fao.org/node/124)
**Traditional medicine.** *M. oleifera* is broadly used in [South Asia](https://www.edgepedia.org/south-asia) and Africa as folk medicine for ailments including paralysis, helminthiasis, sores, and skin infections.[14](https://academic.oup.com/jpp/article/74/3/296/6414694) A systematic review cataloged 163 chemical components in the plant, including flavonoids, carbamates, glucosinolates, and phenols, with reported bioactivities such as anti-tumour, antioxidant, and anti-inflammatory effects.[14](https://academic.oup.com/jpp/article/74/3/296/6414694)
## Evidence on health effects
**Clinical trials remain limited.** The same systematic review concluded that pharmacological studies conducted so far are not sufficient for use in evidence-based medicine, that little clinical trial data exist, and that most studies of constituents such as carbamates and glucosinolates have been conducted only in vitro.[14](https://academic.oup.com/jpp/article/74/3/296/6414694) Animal experiments indicated toxicity limited to the liver, kidney, and blood, and that overdose may cause genetic toxicity.[14](https://academic.oup.com/jpp/article/74/3/296/6414694)
**Cardiometabolic outcomes.** A 2025 meta-analysis of 9 randomized controlled trials (12 study arms, 341 intervention and 308 control participants) found no significant effects on most cardiometabolic outcomes; a modest reduction in diastolic blood pressure (SMD −0.41, 95% CI −0.75 to −0.07) was not robust in sensitivity analyses, and GRADE certainty was very low for all outcomes.[9](https://pmc.ncbi.nlm.nih.gov/articles/PMC12655524/) A separate meta-analysis found no discernible effect of moringa leaf on body weight (WMD −0.06 kg, 95% CI −1.60 to 1.48).[15](https://onlinelibrary.wiley.com/doi/full/10.1002/fsn3.71899)
**Nutrition and lactation.** A systematic review of 33 studies (7 human, 26 animal) found that in humans, higher doses of 14-30 g/day, not lower doses below 10 g/day, improved hemoglobin in children with iron deficiency anemia and improved hemoglobin and vitamin A status in postmenopausal women; 0.5 g/day increased breastmilk volumes. Evidence was described as limited but promising.[16](https://pubmed.ncbi.nlm.nih.gov/35302264/) A meta-analysis of lactating mothers covering 865 participants with exposure up to 180 days found no serious adverse events; minor adverse events occurred in 5 participants (0.3%), all mild nausea or gastrointestinal symptoms.[17](https://link.springer.com/article/10.1186/s43054-026-00539-y)
**Inflammation.** An umbrella review of 26 systematic reviews covering 573 primary articles found leaves to be the most used plant part and flavonoids, phenolic acids, and isothiocyanates the main constituents involved; NF-κB and Nrf2 appear to be the pathways involved in anti-inflammatory and antioxidant mechanisms. However, the included reviews were predominantly of low methodological quality, and translation into clinical practice has not been achieved.[18](https://pmc.ncbi.nlm.nih.gov/articles/PMC12127422/)
## Safety
Within commonly used dosage ranges, trials in adults living with HIV reported no significant adverse events, with kidney and liver function unaffected, though long-term and high-dose safety, particularly in immunocompromised populations, has not been established.[19](https://pmc.ncbi.nlm.nih.gov/articles/PMC12452103/) The genus's roots have been used as a horseradish substitute but may be slightly toxic.[3](https://feedipedia.review.fao.org/node/124)
