Flax Seed is a flower seed that yields linseed oil. Flax Seed is 35-40% oil, the oil is what absorbs and retains the heat which remains inside the seed to be warmed by the microwave. The shell of the seed is soft, allowing moisture from the air to be absorbed for the constant release of moist heat.
Flax Seed, because it is a flower seed, has no cooked food smell in the air or on your clothes because it is not a food product.
Rice will have 10-15% and corn a 4% oil content and has a tendency to develop a bad odor with continued use. Grain products contain mostly water, which cooks out, leaving the heating medium dehydrated so it doesn't hold the heat as long.
Our Body Warmers retain heat for nearly an hour because the oil in the seed has been heated and the shell traps in the heat giving off heat for a longer period of time.
For those sensitive to aromas our flax seed products are unscented. For users who want a scent onto our body warmers we carry Essential Oils that can be sprayed onto the body warmer after removing from the microwave to give you the aromatherapy of your choice.
Just me for your special scent.
