Use it as a heating pad or ice bag.
These linen and cotton bags are filled with cherry pits aromatised with natural lavender. They can be used as a heating pad or an ice bag.
Believe me, I have tried it. I recently had a shoulder Barbotage (treatment for calcifying tendonitis). A bag like this in the freezer for 1 hour, 15 minutes on the shoulder while we watch the news, and we give thanks for simple things like linen and cherry kernels wrapped in spring odour mist.
