Debbie,

Tung oil has high levels of a conjugated triene, α-eleostearic acid (9-cis,11-trans,13-trans-octadecatrienoic acid).  Linseed (flaxseed) oil, has high levels of a methylene interrupted triene, α-linolenic acid (9-cis,12-cis,15-cis-octadecatrienoic acid).  The tung tree originates in southern China.  Flax seed is believed to have originated in the Republic of Georgia.  Distant cousins at best!

Is this a cousin of linseed oil, well-known self-combustible?
