The heating cushions are a tonic in the winter to use instead of hot water bottle (to be heated in the microwave or oven) for muscle pain, rheumatism, but if they do not contain lavender or chamomile flowers, they can also be used as a bag of ice in the summer or in case of sprains, pains, etc. (in a nylon bag in the freezer). They are filled with cherry stones. Complete with cover and instructions. Once you use one you will not want to separate from it.
