This is not mustard oil.  This company has an F rating from the Better Business Bureau.
Reportedly, mustard seed oil is hot and spicy. This is not a hot spicy oil. It looks like almond oil or something. Mustard seed oil reduces scarring. My German Shepherd was attacked by two Rottweilers, and sustained serious injuries. The scarring is bad, and I wanted mustard seed oil to reduce scarring. I have no idea what is in this plastic bottle. It could be anything. If you look at the Better Business Bureau's review of this company, Dr. Adorable, they get an F. All reviewers suspect the oils this Chicago company sells are not what the label say. Amazon needs to take responsibility here, and not let its customers get robbed. If a company has an F BBB rating, how in the world does Amazon end up selling it's "products?" Amazon, you need to step up here.
