Flaxseed provides a gentle, moist heat which promotes healing.
Flaxseeds are flower seeds, rather than grains, so they contain 30-40% oil which remains inside the seed to be warmed again and again. Other products loose their ability to retain heat as the water cooks out of them over time.
When heated, flaxseed pillows retain half their heat after an hour. Under covers (think about those toes…) the pillow will still be warm hours later.
Flax never has that “cooked grain” smell other grain based products have when heated over and over again.
The weight of flaxseed is gentle and comforting.
Flaxseed pillows can also be chilled in the freezer to sooth fevers or slight inflammations, though they don’t get cold enough to provide the numbness needed for things like sprains and back injuries.
