Brazil Nut Oil (Castanha do Par) – Scientific name: Bertholletia excelsa - Obtained From: Seeds - Origin: Brazil - Processing method: Cold-pressed. - Product Abstract - The seed oil is highly nutritious, containing 75% unsaturated fatty acids composed mainly of palmitic, oleic, and linoleic acids, as well as the phytosterol sistosterol, and the fat-soluble vitamins A and E. Extra-virgin oil can be obtained during the first pressing of the seeds, which can be used as a substitute for olive oil.

The proteins in the seeds are very rich in sulfur amino acids, such as cysteine (8%) and methionine (18%); the presence of methionine enhances the adsorption of selenium and other minerals.

It is also considered one of the best conditioners for damaged and dehydrated hair.
