Next to caramel, annatto is the world’s most important natural colorant yielding yellow to red colors. There is global commercial production of the seed, estimated in 1990 at 10,000 tons per year; Brazil being the largest exported.
Atsuete is a tree reaching 4 to 6 meters. Leaves are entire, alternate with long petioles, ovate, 8 to 20 centimeters long, 5 to 12 centimeters wide, with a broad and heart-shaped base, and a pointed tip. The flowers are white or pinkish, 4 to 6 centimeters diameter, 4 to 6 centimeters in diameter on terminal panicles. Fruits are spiny capsules, ovoid or rounded, reddish brown, about 4 centimeters long, and covered with long, slender and soft spines. Fruit dry and split open in two parts exposing many small red seeds covered with a dye-yielding red pulp.
– Planted in and about towns throughout the world.

The main product from B. orellana is an organic dye present in the seed coat called “annatto,” lipid-soluble and widely used in the food industry for its red to orange-yellow colours (cheese, butter, oils, margarine, ice-cream, pastries). Next to caramel, it is the world’s second most important food colorant. Besides providing an attractive color to meat and other dishes, it also imparts a subtle and distinctive flavour. In the cosmetic industry it finds use in hair, nail and soap products, and also in the many of the household products – floor wax, shoe polish, russet leather, wood stains.

Plant showed to be a good source of antioxidants. On repellency testing against A. aegypti, dried seed extracts showed significant skin protection activity. (31)
• Antihistamine / Anti-Inflammatory Activity:
Study evaluated the major constituents of an aqueous extract of B. orellana and its antihistamine activity on acute inflammation-induced model in rats. Results showed anti-inflammatory activity attributed to the inhibitory effect on vascular permeability, suppressed as a result of reduced expression of biochemical mediators (NO and VEGF) in tissues. (see constituents above) (32)
• Poor Wound Healing Activity / Leaves :
Study evaluated the wound healing activity of BO leaf extract in an excision wound healing model on guinea pigs. showed only slight decrease in wound area, not significantly different from the control group. The findings do not support or justify its use in folkloric medicine for wound healing. (33)

(45)
• Open Wound Healing / Seed Oil:
Study evaluated the oil extract of B. orellana as a healing agent in the rat model of open wound healing. Results showed B. orellana oil will hasten the onset of the healing process and its initial phases, but will ultimately produce a scar of poorer quality. (also see 33) (46)
Study of B. orellana through hairy root culture technology yielded secondary metabolites. Compounds 1-10 were evaluated for antimalarial properties. Compound 5 (stigmasterol) was the most potent lead compound. Stigmasterol and the other chemical constituents of hairy roots showed modest antimalarial properties in 3D7 and K1 strains with low toxicity in mammalian cells. (47)
