Bacuri (Platonis insignis) is an ornamental tree, 20-40 m (66-133 ft) tall with a cup like an upside down cone. The fruit is the size of an orange but oval, with a thicker skin of a lemon yellow color. Bacuri is native to the Amazonian rain forest, the bacuri fruit itself has a thick yellow-brown, often mottled skin, making the fruit look a bit like a rounded papaya with a sweet and sour taste with not a very good looking appearance some will refer to it as being ugly. Bacuri belongs to the Guttiferae family and offers many health benefits and is used in ice creams, jellies, sweets, cakes and puree.
Bacuri (pronounced BOK-ur-ri) contains notable amounts of phosphorus, iron, and vitamin C, and is mostly eaten raw or blended into juice. The seeds are used only in certain regions. Locals in the central region of the island Marajó extract the oil from the seeds in a very elaborate, months-long process.
The application of Bacuri butter as herbal medicine is well known on the island Marajó. It is considered an effective remedy for spider- and snake bites. It is also used in the treatment of skin problems and ear pain and is considered to be a miracle cure for rheumatism and arthritis symptoms. Bacuri butter is also known for removing skin patches and renewing scar tissue.
Bacuri butter has a brownish-golden colour and is soft as butter as is expected; the fruit can also be smashed in heated water and passed through a sieve to achieve a dense and aromatic soda. The latex derived from the bark is used in veterinary practice in Guyana. The seeds contain 6 to 11% of oil that is mixed with sweet almond oil and used to treat eczema and herpes.
