Boiled linseed has drying agents added and is not intended for food use. Raw linseed is better but again is not sold as a food product so does not have to declare ingredients. I use either cold pressed raw bought from horse feed merchants or the cold pressed from Sweden but if it was just for personal use I would use walnut oil bought from any supermarket in a small bottle.
