Callaloo is a leafy green vegetable eaten across the Caribbean. The plant here is Amaranthus dubius, a kind of amaranth. It is food first, not a medicine.
The name shifts from island to island. In Jamaica, callaloo means the amaranth leaf. In Trinidad and Tobago that leaf is bhaji, while "callaloo" is a stew made from taro (dasheen) leaves.
Other local names are zepina in Haiti and bledo in the Dominican Republic. The leaf is also sold as Chinese spinach in some shops.
The honest verdict: callaloo is a good source of vitamin A building blocks, folate and vitamin K. Claims that it treats anaemia or "cleans the blood" have not been tested in people. Long use in the kitchen is not proof that it works, and not proof that it is safe.
Callaloo acts as food. Its effects come from the nutrients in the leaf, not from a drug-like action.
Cooked leaves give beta-carotene, which your body turns into vitamin A. They also give folate, vitamin C, vitamin K and potassium. These nutrient roles are well established in people.
The leaf also holds oxalate, a natural plant acid. In lab work, oxalate binds iron and calcium and makes them harder to take up. So the iron in callaloo is likely absorbed less well than iron from meat or fish.
Lab and animal studies report that amaranth leaf extracts can mop up free radicals. Some rodent work also shows lower blood sugar and blood fats. These are early findings, and nobody has shown the same thing in people eating callaloo.
Callaloo is sold mostly as a vegetable, not as a remedy.
- Fresh bunches of leaves and soft stems - Frozen chopped leaf - Canned callaloo, often salted - Dried leaf and leaf powder - Amaranth leaf capsules, sold as a food supplement
Canned types can be high in salt. Powders and capsules are not standardised, so strength varies by brand. The amaranth grain sold for porridge comes from related species, not from this leaf crop.
Amaranth greens have been eaten in the Caribbean for centuries. The plant grows fast in hot, wet ground and spreads like a weed.
Indigenous American, African and Indian food ways all shaped how it was cooked. Names changed by island: bhaji in Trinidad and Tobago, zepina in Haiti, bledo in the Dominican Republic.
Home tradition treated callaloo as a strengthening food. Cooks gave it in broth to new mothers, to children and to people getting over illness. Older people often spoke of it as food that "builds blood".
In Jamaica, the steamed leaf is a breakfast dish with saltfish. In Trinidad, callaloo on a menu usually means the taro leaf stew. The name alone does not tell you which plant is in the pot.
Stop eating it and get medical advice if you react badly.
- Sharp pain in your side or back, or blood in your urine: this can be a kidney stone - Rash, itching, or swelling of the lips, tongue or throat: call emergency services - Trouble breathing after eating it: call emergency services
- Grey or blue lips or skin in a baby: this is an emergency - Lasting tiredness, pale skin or breathlessness: anaemia (low red blood cells) needs a blood test
Also tell your doctor if you take warfarin and your diet has changed a lot.
Callaloo is an ordinary food. It is sold freely as a fresh, frozen or canned vegetable in the Caribbean, the United States, Canada and the United Kingdom.
Leaf powders and capsules are sold as food supplements. No country has approved callaloo as a medicine for any illness.
