What natural remedies are there for hand foot and mouth disease? Has anyone tried coconut oil or tumeric for sores?

My daugther had HFMD before. What we did was offering cold beverages and ice pops to ease her pain in the mouth and throat. For blisters on hands and feet, I applied calamine lotion for her to soothe the pain. Try to let the child drink more vitamin C water to let the body heals faster and build up the immune system during HFMD.
