From the rfc FAQ:

MUSTARD OIL - This spicy oil is extensively used in Bengali and some
other Indian cuisines. It is said that it is very hard, if not
impossible, to find good quality mustard oil outside of India. In the
'Western' countries, mustard oil is required to be sold with a "for
external use only" warning, since it contains allyl isothiocyanate and
erucic acid, both of which have been implicated in some health problems.
