Perilla oil

Description

A light yellow drying oil expressed from the seeds of mint plants (Perilla ocymoides or Perilla frutescens) native to Asia (China, Korea, Japan and northern India). The seeds contain 35 to 45 percent oil. Perilla oil contains primarily linolenic (41-46%), linoleic (31-42%), and oleic (3-10%) acids. It has been used as a Linseed oil substitute in house paints, varnishes and linoleum, but is not recommended for use as an artist paint because it yellows with age. Perilla oil is also used for cooking, dressing leather, and as a component in inks.
