Mike Wyleover 1 yearMustard oil Yes or No ?7 comments,0 shares,0 likesHari Ghotraover 1 yearI like to use it in specific dishes - veg dishes and fish dishes too. And yes heat it to high then let it cool before using.booover 1 yearMustard oil is said to be slightly toxic due to its high level of erucic acid. But there is no danger if you heat it up for deep frying. And a spoonful of mustard oil for the wonderful flavour now and then will do no harm! As @Arthur vdH mentioned, millions of Indians have used it for ages!! @Mike WyleJo dunnover 1 yearhttps://www.harighotra.co.uk/blog/first-edible-mustard-oil/ampJo dunnover 1 yearDefinitely yes @Mike Wyle. @Hari Ghotra has written Mustard Oil - Finally Edible Thanks to KTCArthur vdHover 1 yearThere have been tests in India, one result being that it offers slight protection against heart diseases, another that it doesn’t. But if millions of people have been using it for ages you can be pretty sure that it’s safe to use as traditionally used. If it were unsafe, people would have noticed and stopped using it.Mike Wyleover 1 yearYeah test was never done on humans was it ?Arthur vdHover 1 yearYes. Unless you’re a male lab rat, then no.
