Botanical source

Unrectified cade is still produced in the Atlas mountains of Morocco, where it has been used in traditional medicine for centuries, particularly for skin lesions.

'Medicinal tar' in the traditional pharmaceutical sense is produced from Juniperus oxycedrus, J. phoenicea, J. thurifera and several other plant species.


Notes

IFRA prohibits crude cade as a fragrance ingredient. Only rectified is regulation-compliant. If a label reads 'cade oil' without specifying rectified, assume crude and do not use.
