Application wrap: For best results, place 100g of bexters soda crystals into a purpose-made bexters crystals application wrap/mitt and apply directly over the swollen area. Leave the wrap/mitt secured for a minimum of 3-4 hours, preferably overnight. As excess fluid may be absorbed, a towel or waterproof sheet should be placed under the treatment area. Alternatively, a light weight cotton sock can be used in place of an application wrap/mitt. Dispose of the crystals after each use. Do not reuse crystals. Recommended for use on alternate days. Aches and Pains Whole body: Completely dissolve 200g of crystals in a full bath and soak for up to ½ hour. Use 100g for sensitive skin. Take extra care stepping in and out of bath as it will be very slippery. Refer to warning advice. Bath water may be recycled for use on lawn. Foot/Hand: Dissolve 100g of crystals in a basin of warm water. Soak for up to ½ hour
