What is moringa leaf?
Moringa is the leaf of a fast-growing tree, Moringa oleifera. In West Africa it is treated as a food first. The Hausa name is zogale, and the leaves go into soups, stews and relishes.
The leaves are dried and ground into a fine green powder. That powder is now sold worldwide as capsules, tea bags and smoothie mixes. The same tree gives edible pods, called drumsticks, and seeds that are pressed for oil.
Here is the honest verdict. As a leafy green, moringa is a genuinely good food, rich in vitamin A, vitamin C, calcium and iron. As a medicine, the human evidence is thin and the trials are small.
Long use in a tradition is not proof that a remedy works, and it is not proof that it is safe. Moringa leaf itself has a good record as food. The root and root bark are a different matter, and are not safe to take.
How is moringa supposed to work?
Two things are going on here, and only one of them is settled.
The settled part is simple nutrition. Dried moringa leaf does supply vitamin A, vitamin C, calcium, iron and some protein. In a diet short of those, the leaf fills a real gap.
The unsettled part is the drug-like claims. In cell studies, compounds from the leaf appear to damp down signals linked to inflammation. In rats and mice, leaf extracts have lowered blood sugar and blood fats.
Some lab work also suggests the leaf slows certain bacteria in a dish. Whether that happens inside the body is not known.
Whether any of this works at useful levels in people is not established. Human trials are small, short and often poorly blinded. Treat the lab findings as leads, not as results.
What forms does moringa come in?
Most moringa sold as a supplement is dried leaf powder, loose or in capsules.
- Fresh leaves, cooked into soups and stews - Dried leaf powder, stirred into food or drinks - Capsules and tablets of leaf powder - Leaf tea bags - Seed oil, also called ben oil, used on skin and in cooking - Whole seeds, eaten roasted or used to settle muddy water - Root and root bark preparations
Steer clear of that last group. Root and root bark carry spirochin and have caused poisoning.
Quality varies a lot between brands. Leaf powder has been found contaminated with lead or with bacteria in some market surveys. Buy from a seller who tests their batches.
Where does moringa come from?
Moringa grows across the Sahel and in South Asia. In Hausa-speaking northern Nigeria and Niger it was known as zogale. Cooks used the leaves as a daily vegetable, and healers used them for weakness, swelling and poor appetite.
It was prized because it keeps its leaves in the dry season. When other greens failed, moringa kept producing. That made it a famine food as much as a remedy.
The tree also has a long record in Ayurveda, the traditional medicine of India. There the pods and leaves were used for digestion and for joint pain. Seeds were used for centuries to clear muddy water.
In the twentieth century, aid programmes promoted the leaf for child nutrition. Marketing later rebranded it as a superfood. The food use is old; the supplement industry around it is recent.
When should you see a doctor?
Stop and get medical advice if you notice any of these:
- Swelling of the lips, face or throat, or trouble breathing; this needs emergency care now - Signs of low blood sugar, such as shaking, sweating, confusion or faintness - Dizziness or blackouts when you stand up - Yellow skin or eyes, dark urine, or pain under your right ribs - Vomiting, severe cramps or diarrhoea that does not settle
Get urgent help if anyone has swallowed a root or root bark preparation.
Also see your doctor before using moringa if you are on any regular prescription, or if you are using it in place of treatment for diabetes or high blood pressure.
In the UK, the EU and the US, moringa leaf is sold as a food or a food supplement, not as a licensed medicine. No regulator has approved it to treat or prevent any disease. In much of West Africa and South Asia it is simply a common vegetable.
