Achiote

Achiote may be lesser known among the common household spices, but this fragrant and colorful herb can actually be found in many homes around the world, either explicitly added for cultural significance or subtly present as a dye in processed foods. Its nuanced presence, however, belies its original use as a powerful natural medicine.

Health Benefits of Achiote

The unique combination of bixin, antioxidants, and tannins found in achiote seeds can provide the following medicinal benefits:

  • Speeding up wound healing. Like most carotenoids, bixin possesses strong anti-inflammatory action, which can soothe burns and blisters on the skin when applied topically.

  • Supporting the treatment of stomach parasite infections. When combined with astringent tannins, achiote's anti-inflammatory action is thought to possess mild antimicrobial and antifungal effects, alongside significant antiparasitic activity.

In addition, the bark and root of achiote has been traditionally used to reduce fever, inflammation, and stomach infections.

How It Works

The main compound responsible for achiote's medicinal benefits is a carotenoid known as bixin, which is also responsible for the herb's bright orange-red color. In addition, achiote seeds contain a significant amount of tryptophan and threonine, two essential amino acids. Furthermore, the flavonoids and other antioxidant compounds found in achiote act as free radical scavengers in the bloodstream, and are thus believed to delay oxidative damage, although the full extent of this property or its implications is still to be confirmed.

The nutritional value of achiote is intensified by the presence of vitamin E (as tocotrienol), different flavonoids, tannins, sterols, and saponins.

Anti-inflammatory properties are also present in aloe and greater plantain, whereas elecampane and papaya seeds can provide similar antiparasitic benefits.

Side Effects

Achiote is considered generally safe; however, it can cause allergic reactions in sensitive people. Symptoms include anaphylactic shock and hives. 

Overconsumption of achiote can cause diarrhea and gastrointestinal discomfort.

Cautions

Although no drug or supplement interactions have been reported for achiote, the herb has shown hypoglycemic effects, so diabetics under glucose control medication are advised to consult to a health professional before consuming achiote in medicinal doses.

While no adverse reactions have been reported, because of the lack of information on achiote during pregnancy and breastfeeding, it is advised to limit the consumption of the herb in women going through these stages.

How to Consume Achiote

Achiote is mostly used for culinary purposes; however, it is rich in anti-inflammatory and antioxidant compounds, and various medicinal preparations are meant to take advantage of these properties.

Remedies

Main preparations: Liquid extract, capsules, infusion, pulp

  • Liquid extract. These products are typically made from the seed powder.

  • Capsules. This preparation offers controlled dosage of the herb. They are typically taken to reduce inflammation or for their antioxidant properties.

  • Infusion. In traditional medicine, achiote tea made from the plant's roots and leaves has been used to relieve respiratory inflammation, such as a sore throat.

  • Pulp. The seed pulp has been applied traditionally to burns and wounds.

Food

Achiote seed powder or paste is used as a seasoning and coloring, especially in Latin American food. It is unclear whether or not the amount typically consumed in dishes is sufficient to provide anti-inflammatory benefits.

Buying

Raw and Simply Processed Achiote

Due to its tropical growth requirements, achiote trees are largely restricted to their native and naturalized regions, though seeds and roots can be found in select specialized health food stores and ethnic markets. They may come whole, but the more common presentation around the world is as a finely ground powder, which makes shipping and home use an easier process. Teas and infusions that utilize the herb can be found in similar locations or even online.

Achiote Supplements

It is currently easiest to find achiote supplements via online retailers, which offer the widest selection of brands, prices, and concentrations. Powders and liquid extracts are the most common, but capsules are also carried at some outlets. As awareness of achiote's benefits continues to grow, it's possible that more products will become mainstream in the future.

Growing

Quick Facts (Growing)
  • Life cyclePerennial
  • Harvested partsSeeds
  • Light requirementsFull sun
  • Soil pH6.1 – 6.5 (Slightly acidic)
  • Growing habitatTropical rainforests

A tropical perennial shrub, achiote, annatto, or lipstick tree, is grown mostly as an industrial crop, although in India, where conditions are conducive to its propagation, it is also cultivated as an ornamental plant.

Growing Guidelines

  • Temperatures between 82 - 112°F (28 - 44°C) and ten hours of daily sunlight are required for proper development.

  • Precipitation levels should, ideally, range from 31 - 59 inches (800 - 1,500 mm) each year.

  • Slightly acidic soil that offers good drainage works best, and flowers and fruit start to form three years after planting.

  • Stable plants can live for 20 - 25 years.

Additional Information

Plant Biology

Achiote is an evergreen that can grow up to 25 feet (7.6 m) tall and has large, broad leaves and pink or white flowers. Its red, spiny fruit can either be smooth or found covered in dense bristles. When ripe, approximately 50 seeds and a red seed pulp are harvested from within.

  • Classification

    Achiote (Bixa orellana) is a member of the Bixaceae family and, as the most famous of these 25 species, its name is sometimes used as a colloquial umbrella term for this diverse group of trees, herbs, and shrubs.

  • Varieties and Subspecies of Achiote

    There are three varieties of achiote in existence today, differentiated by the colors of their flowers and seeds. However, these do not have specific names, and there are no true subspecies, given that the change in genetic composition is so slight. Trees that feature white flowers tend to produce seeds with green capsules; those with purple flowers come with brownish-red capsules; and those with pink flowers yield capsules of a truer shade of red. Difference in color appears to have no bearing on medicinal efficacy or taste.

Historical Information

Achiote was well-established in human culture well before its official discovery, though records don't indicate exactly how far back its use stretches. It is known, however, that the herb was prized by Mayan and Aztec civilizations and used as part of religious ceremonies as a representation of blood. It was also employed as a cosmetic, body paint, food dye, and herbal medicine. European discovery by Spanish and Portuguese settlers led to its existence in the Western world, though it continued to remain more popular in imperial colonies, taking root in India, Sri Lanka, and even Eastern Africa.

Economic Data

Despite the little publicity that achiote receives, today it is a thriving part of international crop cultivation, used mainly for manufacturing Annatto Red, a very popular food coloring. The U.S., which imports approximately 40% of the world's supply, is particularly interested in the herb, since the country's Food and Drug Administration (FDA) does not require annatto dyes to be certified for use. Brazil and Peru lead achiote production, yielding roughly 5,500 tons of the plant's seed each year, with Kenya following close behind.

Other Uses

A multipurpose plant, achiote has found diverse other uses over the years, starting as an insect repellent and dye not only for the skin but also for cloth and leather. It also works as a natural cosmetic, generating the nickname "the lipstick tree" for this reason.

Furthermore, achiote is an effective nontoxic sunscreen, and the fruit provides animal fodder. The tree's bark is quite flammable and is a source of fuel in some places.

In India, the tree itself is a popular ornamental plant, and the seed paste is dotted on women's foreheads as a sign of marriage.

Its pulp is what grants achiote industrial value, since it contains bixin, which is widely used for making natural food colorants.
