What is aguaje?
Aguaje is the fruit of the moriche or buriti palm, Mauritia flexuosa. The palm grows in swampy ground across the Amazon basin. In Peru, Brazil, Colombia and Venezuela the fruit is an everyday food.
The fruit is small and oval, with red-brown scaly skin. Under the skin sits a firm orange pulp. That pulp is one of the richest known plant sources of beta-carotene, which your body turns into vitamin A.
People eat it fresh or soaked soft. It is also sold as juice, ice cream, sweets, dried powder and capsules. The pulp and seeds give buriti oil, used on skin and hair.
Here is the honest verdict. As a food, aguaje is a well documented source of provitamin A and healthy fats. The popular claims, that capsules reshape the body or balance hormones, are not supported by human trials.
Long use in a tradition is not proof that something works. It is also not proof that it is safe.
How is aguaje supposed to work?
One part is simple and established. Aguaje pulp is packed with carotenoids. Your body converts these into vitamin A, which your eyes, skin and immune system need.
The hormone story is a different matter. Aguaje contains plant sterols, including beta-sitosterol and stigmasterol. Marketers call these "plant oestrogens" and claim they add curves or ease menopause.
That claim has not been tested properly in people. Plant sterols can bind weakly to oestrogen receptors in laboratory work. Whether eating aguaje changes hormone levels in a human body is simply not known.
In test-tube studies, aguaje extracts mop up free radicals, which are unstable molecules linked to cell damage. In animal studies, buriti oil has shown anti-inflammatory and wound-healing effects. Neither finding tells you what happens in a person.
On skin, the oil works mostly as a plain emollient. It is thick, fatty and holds water in the skin. That part needs no special theory.
How is aguaje sold?
Most of it is eaten as food. Common forms include:
- Fresh fruit, soaked in warm water to soften the pulp - Frozen or pasteurised pulp - Aguajina, a sweet drink made from the pulp - Ice cream, sweets, jam and yoghurt - Dried pulp powder and aguaje flour - Capsules and tablets, often sold for "curves" or menopause - Buriti oil, for skin, hair and soap
Food forms and capsules are not the same product. A capsule gives a small, concentrated dose of pulp powder or extract. A bowl of pulp gives far more fibre, fat and carotenoid.
Buriti oil is normally used on the skin. Culinary oil exists but is less common outside the region.
Where does aguaje come from?
Moriche palm has been used by Amazonian peoples for a very long time. Groups in Peru, Brazil and Venezuela called it a tree of life, because it gave food, fibre, thatch and oil.
The fruit was eaten fresh and made into drinks and pastes. The oil was traditionally applied to burns, scrapes and dry skin. Palm hearts and larvae from fallen trunks were also eaten.
In the twentieth century the fruit became a street food in Iquitos and other Amazon cities. Around that time a folk reputation grew up in Peru. Aguaje was said to give women a fuller figure and to ease the change of life.
That reputation drove today's capsule market. It was never based on trial evidence.
When to see a doctor:
Stop and seek urgent care if you get swelling of the lips, face or throat, hives, or trouble breathing. That can be an allergic reaction.
See a doctor soon if the whites of your eyes turn yellow. That is jaundice, not harmless carotene colouring, and it needs checking.
Also see a doctor if you have any bleeding after menopause, or if menopause symptoms are disrupting your life. Do not try to manage these with supplements alone.
In Peru, Brazil and Colombia aguaje is an ordinary food sold openly in markets. In the UK, EU and United States it is treated as a food or food supplement, not a medicine. Supplement sellers there may not legally claim it treats any disease.
