Valerian for stomach flu cramping?

Help! My daughter has had that awful stomach flu for 3 days straight. (she's 18) No vomiting. Just fever and diarrhea. Got the fever under control, but the diarrhea and especially the cramping won't go away. Called the doctor - - - nurse said Kaopectate is better than the anti-diarrhea pills (which didn't work when we tried them). After several dosages of Kaopectate, she is still having cramping every couple of hours.

Yes, I'm pumping fluids into her as much as possible. No solid foods. But I've read online that the herb pills, Valerian, may help relieve intestinal cramping. I have some. Should I give it a try?

P.S. She can't very well go to the doctor's office and wait to be seen in the condition she's in. I asked them to prescribe Lomotril, but they want me to wait another day to see if the Kaopectate works. UGH, but I don't see improvement yet! She has nothing left in her intestines to empty - - - - and I hate to see her keep suffering. Suggestions???

Not heard of valerian for poorly tummy but - have heard of Slippery Elm - soothing herb for the gut (gastro-intestinal tract). If you have wounds (ulcers), spasm or inflammation anywhere in the gut, drink lots of Slippery Elm Tea (actually - it's more of a 'gruel' - like thin porridge). Slippery Elm is very benign - that is, very safe. You can even make your 'porridge' thick - and use it externally to help healing. Slippery Elm has a reputation for being nourishing and easy to digest - hence its use to assist recovery from a long illness, and for the elderly.

I have no idea what it tastes like tho
