Wheat bags have become very popular in recent times to use for theraputic uses such as various types of muscular, back and arthritic pains. Our heat packs can also be used as cold packs for head aches or sport injuries.For coldpack place bag in sealed plastic bag and place in freeza for at least 1 hour before needed. For heating just place bag in microwave for 1 and a half to 2 mins. (depending on watts).ALWAYS place a mug of water in microwave so the wheat doesn't over heat and spark. It adds a small amount of moisture to the pack.Never over heat as sparks can lead to fire.Because our packs are scented with pure essential oils you will also have the theraputic qualities too. Lavender - headache and stress. Rose Geranium - nausea and PMS relief. Cinnamon and spices -Temporary relief of rheumatic pain.The pack should mould or contour the area to be treated and generally last for approx 30 mins.Use over and over again. Pure luxury!
