Traditional uses

Long before it colored supermarket cheese and butter, annatto was one of the most treasured plants of the Maya and other Indigenous peoples of tropical America, who ground the seeds into a vivid paste for body paint, ceremonial dye, and cooking. Traditional healers across Central and South America have used seed preparations to soothe upset stomachs, calm skin irritation, and cool a fever. Spanish colonizers carried the seeds back across the Atlantic, and annatto followed trade routes into Caribbean, Filipino, and West African kitchens, where it remains a beloved souring and coloring agent in dishes like cochinita pibil and Filipino kare-kare. Today it is best known as the natural source of that warm orange-red hue in cheeses, margarine, and smoked fish.

Did you know?

The bright red-orange pigment in annatto seeds, called bixin, is the same coloring long used to tint cheddar cheese, butter, and smoked fish, and it earned the plant its common nickname, the lipstick tree, because Indigenous peoples of the Amazon crushed the seeds into a paste for body paint and ceremonial adornment.

Safety

Annatto is safe in normal culinary amounts. In concentrated doses it may lower blood sugar or affect blood thinners and blood pressure medication, so use caution beyond food amounts if you take those; rare allergies have been reported.
