This is one of those topics that has been brought up in the past. The oil recommended is Extra Virgin Siberian Pine Nut Oil, 8.5 oz bottle costs = $45.95.
The Ads claim: Three teaspoons of delicious extra virgin pine nut oil daily
is all you need to heal your gastrointestinal lining, boost your metabolism and
optimize your digestion and nutrient assimilation.
I am leery of anything than is "all you need" to cure GERD and help you lose weight too.
