Moringa (Moringa spp.)
While some complementary and alternative techniques have been studied scientifically, high-quality data regarding safety, effectiveness, and mechanism of action are limited or controversial for most therapies. Whenever possible, it is recommended that practitioners be licensed by a recognized professional organization that adheres to clearly published standards. In addition, before starting a new technique or engaging a practitioner, it is recommended that patients speak with their primary healthcare provider(s). Potential benefits, risks (including financial costs), and alternatives should be carefully considered. The below monograph is designed to provide historical background and an overview of clinically-oriented research, and neither advocates for or against the use of a particular therapy.
Moringa has been used in a variety of industrial, folkloric, dietary, and medicinal practices. For cooking, moringa has been used as a frying oil and food seasoning and has been eaten as part of curries and salads. Due to its many healthy components, moringa has also been used as a nutritional supplement. Such components include amino acids, antioxidants, fat, minerals, protein, and vitamins. Moringa is thought to contain more vitamin C than oranges, more potassium than bananas, more iron than spinach, and more protein and calcium than milk.
The use of moringa in traditional medicine reportedly dates back to ancient times. In spite of the many historical uses of moringa, high-quality research on its proposed health benefits is currently lacking. Limited research in humans suggests that moringa may be used to treat asthma, malnutrition, and lack of vitamin A, and to purify water. In other research, moringa leaf was shown to increase breast milk production in the early period after childbirth. Further research is needed in these areas.
These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
|Breast milk stimulant
Moringa leaf has been used traditionally to promote breast milk production. Products such as Natalac, Go-Lacta®, and Prolacta® have been studied for this use. In human research, moringa leaf was shown to increase breast milk production in the early period after childbirth. More studies are needed to confirm these results.
Limited research suggests that seed kernels from Moringa oleifera may be used for the treatment of bronchial asthma. Further research is needed in this area.
According to early research, Moringa oleifera leaf powder taken together with ground soybeans and peanuts may increase the weight of underweight children. Further research into the effects of Moringa alone is needed in this area.
|Vitamin A deficiency
Limited research suggests that Moringa oleifera may improve vitamin A deficiency, and increase the availability of beta-carotene, a vitamin A precursor. When combined with nutritional counseling, Moringa oleifera may be used as a replacement for synthetic vitamin A supplements in children. More high-quality studies are needed in this area.
Moringa oleifera has shown opposing effects for water purification. Although moringa has been shown to lower bacteria levels initially, this effect appears to disappear over time. As well, moringa lacked any benefits compared to chlorine, an agent commonly used to purify water. Although promising, further research is needed in this area.

The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.
Adults (18 years and older)
Factors such as age and health may affect the amount of Moringa prescribed to different people.
For asthma, three grams of dry, powdered Moringa oleifera seed kernel has been taken by mouth twice daily for three weeks.
As a breast milk stimulant, the following has been taken by mouth: a moringa capsule (commercial preparation containing 250 milligrams of moringa leaves) every 12 hours on days 3 to 5 after childbirth; 2 moringa capsules (Prolacta®, 350 milligrams per capsule) 3 times daily until ≥ 3 days before delivery.
Children (under 18 years old)
Insufficient available evidence.
The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.
Avoid in people with known allergy or sensitivity to Moringa species.
Side Effects and Warnings
Moringa leaves and seeds are likely safe when taken, based on the amounts used in typical dietary or traditional health practices.
Moringa may increase the risk of bleeding. Caution is advised in people with bleeding disorders, and in those taking drugs that may increase the risk of bleeding. Dosing adjustments may be necessary.
Moringa may lower blood sugar levels. Caution is advised in people with diabetes or hypoglycemia, and in those taking drugs, herbs, or supplements that affect blood sugar. Blood glucose levels may need to be monitored by a qualified healthcare professional, including a pharmacist. Medication adjustments may be necessary.
Moringa may stimulate the heart and increase blood pressure. Other research suggests that moringa may cause low blood pressure. Caution is advised in people with heart or blood vessel disorders, and in those taking drugs, herbs, or supplements to treat these conditions.
Moringa may increase the flow of urine. Caution is advised when using other agents that may also increase urine flow.
To purify water, use cautiously during outbreaks of intestinal infections.
Avoid consuming moringa root bark and ethanol extracts of moringa leaves and seeds, due to toxic effects. Only minute amounts of moringa root flesh may be consumed due to its spirochin content. Spirochin is a compound that may cause loss of nerve function.
Moringa may increase the risk of developing an enlarged thymus gland. Avoid in people with thymus disorders and in those taking drugs, herbs, or supplements to treat these conditions.
Moringa may increase the risk of neck swelling due to an enlarged thyroid gland. Avoid use of high doses in areas deficient in iodine.
Avoid doses of moringa crude extract in doses greater than 46 milligrams per kilogram of body weight weekly, or seven milligrams per kilogram daily. High doses may have a negative impact on liver and kidney function.
Moringa may prevent implantation and induce abortion. Avoid use in women who are pregnant or trying to conceive. However, in human research of pregnant women ≥ 36 weeks gestation, adverse effects associated with use of moringa leaf to promote breast milk production were lacking.
Avoid use in children, due to a lack of safety information.
Avoid with known allergy or sensitivity to Moringa species.
Pregnancy and Breastfeeding
Moringa may prevent implantation and induce abortion. It is not recommended for use in women who are pregnant or trying to conceive. However, in human research of pregnant women ≥ 36 weeks gestation, adverse effects associated with use of moringa leaf to promote breast milk production were lacking. Moringa leaf has been used traditionally to promote breast milk production. Products such as Natalac, Go-Lacta®, and Prolacta® have been studied for this use. In human research, moringa leaf was shown to increase breast milk production in the early period after childbirth. More research is needed in this area.
Most herbs and supplements have not been thoroughly tested for interactions with other herbs, supplements, drugs, or foods. The interactions listed below are based on reports in scientific publications, laboratory experiments, or traditional use. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy.
Interactions with Drugs
Moringa may increase the risk of bleeding when taken with drugs that increase the risk of bleeding. Some examples include aspirin, anticoagulants (blood thinners) such as warfarin (Coumadin®) or heparin, antiplatelet drugs such as clopidogrel (Plavix®), and nonsteroidal anti-inflammatory drugs such as ibuprofen (Motrin®, Advil®) or naproxen (Naprosyn®, Aleve®).
Moringa may lower blood sugar levels. Caution is advised when using medications that may also lower blood sugar. Patients taking insulin or drugs for diabetes by mouth should be monitored closely by a qualified healthcare professional, including a pharmacist. Medication adjustments may be necessary.
Moringa may interfere with the way the body processes certain drugs using the liver’s cytochrome P450 enzyme system. As a result, the levels of these drugs may be increased in the blood and may cause increased effects or potentially serious adverse reactions. People using any medications should check the package insert and speak with a qualified healthcare professional, including a pharmacist, about possible interactions.
Moringa may also interact with acetaminophen, agents that affect blood pressure, agents that affect the heart, agents that affect the kidneys, agents that affect the immune system, agents that affect the nervous system, agents that affect the stomach, agents that are toxic to the liver, agents used to increase breast milk, antiarsenic agents, antiasthma drugs, antibiotics, anticancer agents, antifungals, antiparasitics, antivirals, aspirin, carbon tetrachloride, chelating agents (chemical agents that bind metal particles), drugs that reduce eye clouding, fertility agents, inflammation-lowering agents, lipid-lowering agents, mosquito repellants, pain-relievers, penicillin, pentobarbitone, radiation therapy, rifampin, scopolamine, spasm-reducing agents, testosterone, thyroid hormones, tuberculosis treatments, urine-promoting agents, and wound-healing agents.
Interactions with Herbs and Dietary Supplements
Moringa may increase the risk of bleeding when taken with herbs and supplements that are believed to increase the risk of bleeding. Multiple cases of bleeding have been reported with the use of Gingko biloba, and fewer cases with garlic and saw palmetto. Numerous other agents may theoretically increase the risk of bleeding, although this has not been proven in most cases.
Moringa may lower blood sugar levels. Caution is advised when using herbs or supplements that may also lower blood sugar. Blood glucose levels may require monitoring, and doses may need adjustment.
Moringa may interfere with the way the body processes certain herbs or supplements using the liver’s cytochrome P450 enzyme system. As a result, the levels of other herbs or supplements may become too high in the blood. It may also alter the effects that other herbs or supplements possibly have on the P450 system.
Moringa may also interact with agents that affect blood pressure, antiarsenic herbs and supplements, antiasthma herbs and supplements, antibacterials, anticancer agents, antifungals, antioxidants, antiparasitics, antivirals, calcium, chelating agents (chemical agents that bind metal particles), fertility agents, herbs and supplements that affect the heart, herbs and supplements that affect the kidneys, herbs and supplements that affect the immune system, herbs and supplements that affect the nervous system, herbs and supplements that affect the stomach, herbs and supplements that reduce eye clouding, herbs and supplements that are toxic to the liver, herbs and supplements used to increase breast milk, inflammation-lowering herbs, lipid-lowering agents, mosquito repellants, pain-relievers, probiotics (healthy bacteria), spasm-reducing agents, tamarind, urine-promoting agents, vitamins A and E, and wound-healing herbs and supplements.
