I bought some slippery elm powder from a health food store based on an online article. You make a tea with it, and drink to coat and protect your throat and digestive system. My husband has acid reflux and says it is helping so far.
This was recommended to me but it did absolutely nothing in the way of help.
If it is helping your husband that's great.
I'm all for trying different things. I found Aloe Vera helpful myself.
I wish you well and your husband,
