I've recently been researching the work of Dr. Price and the X-factor that high vitamin butter, combined with fermented cod liver oil, will cause teeth to re-mineralize and stop tooth decay. If this is why you want to purchase this product, DO NOT. I'm sure it's fine for ghee, but when I switched from the pricey butter oil to this, I found cavities were growing. When I switched back, they stopped growing. Again, this is great for ghee, but don't use as part of preventing/curing tooth decay as Dr. Price's research recommends.
Ok for cooking, do NOT USE for preventing cavities
