I think it’s called acetone it’s like the smell of nail varnish remover when I take two Peppermint Oil Caps with a cold drink
Not every time but some After around 10 mins of taking I burp what I can only describe as nail polish remover taste/smell it’s very strange but I’m in no discomfort I take with 20 billion Live Friendly Bacteria Mebeverine and Pantoprazole My symptoms have got a lot better
