It is made from non-toxic ingredients; sodium-acetate (salt & vinegar). When you click the button the vibration makes the salt form a crystal and as it crystallizes, it naturally heats up. When you have activated the pack, make sure you squeeze and/or massage the pack which will make it stay hot longer. The packs will stay hot for between 30 minutes and 2 hours, depending on the pack size.
They are highly recommended by Physiotherapists, Chiropractors and practitioners of natural medicine because of their natural heat. It is like the heat you get when sitting in the sun; it does not burn you (54- 57 ? C). The natural heat opens up the pores, lets the oxygen in and the blood circulates to that part of the body. Most of the time you have pain because blood is not circulating to that part of the body; this product helps to get the blood circulating instantly.
Furthermore, it is great for massage. It opens up the pores and allows massage oils to be more readily absorbed. It also prepares the skin for massage by bringing the blood to the surface. This reduces over-working the skin and risk of bruising.
After you have used the pack and the heat has gone, you just put it in boiling water (in a pot or sterilising unit) for approximately 5-10 minutes. Because it is natural, the salt will melt and go back to liquid. Boiling the pack also sterilises it so that it is fresh and ready to use for next time.
