Very helpful
Size: 1.5 Ounce (Pack of 5)
My husband had throat cancer approximately 5 years ago. Treated with chemo and radiation. The radiation burned his saliva glands. This really helps him keep moisture in his mouth. I have it on an auto delivery every 6 weeks (pack of 6)

Part of my daily routine for radiation caused dry mouth
Size: 1.5 Ounce (Pack of 5)
This product and xylitol lozenges by xylimelt plus taping my mouth closed as night for sleep make for a comfortable solution to my radiation induced dry mouth condition. Recommended.
