Lallemantia oil is a seed oil, extracted from the seeds of the Lallemantia iberica . It contains 68% linolenic acid, making it an unusually rich source, and of potential commercial interest. [1] Lallemantia oil has been discovered at a number of archeological sites in northern Greece, dating from the Bronze Age. [2] As the plant is not native to this region, the presence of this oil suggests that it was imported from further east.
Lallemantia oil is a drying oil, and can be used as a substitute for linseed oil in this and other contexts. [3] The oil is also edible. [4]
