I bought fenugreek seeds on a whim remembering I'd seen them in recipes. I can't find the recipes, but I have heard they were good as a tea. I'll def. try this, more for PMS than gas though.
I love cabbage, I've always simmered it with tumeric so maybe that helps with the gas. Cabbage, noodles, kasha, curry powder and a handful of golden raisens.
Ginger tea is my go to for stomach ills.
