I've been experiencing nausea every night for months. Went to the docs twice, said it could be gastritis or acid reflux.
I was reading up on some Edgar Cayce remedies and his suggestion of slippery elm bark (the loose powder form) is the one remedy that has been helping me.
I put an 1/8th of a teaspoon in a cold glass of water in the morning. Let it sit for a few minutes, stir, then drink.
I've tried nearly every other home remedy and nothing else helped. I figured maybe it could help others out there as well. Cayce also suggested American saffron tea. Haven't tried it but I will be soon.
Note: don't take other supplements 2 hours before or after drinking this as it may hinder absorption.
