Peanuts come under the name of:
ground nuts, earth nuts, monkey nuts.

Some minor food ingredients may be derived from peanuts:
hydrolysed vegetable protein, food additives E471 & E472 (a-e) & lecithin.

Check 'specialised formulas' and old stocks of formula for addition of arachis
oil.

Check baby massage oils and skin creams.

If peanuts or peanut oil enters the trachea it may cause terrible damage to
the lung, so throwing up a peanut and catching it in the mouth - considered to
be a good 'party trick' by many - is a very very dangerous thing to do no
matter how old you are.  Not only may one fall prey to choking but also the
oil from the nut is such an irritant.
I have had the misfortune to know two people who have lost a lung because of
inhalation of peanut.

It is recommended that young children with a personal or family history of
allergy should not be given peanuts in any form and that these children are
not given peanuts or nuts in their diet until at least three years old, some
authorities say seven years.

Most of the above is gleaned from an article in National Childbirth Trust New
Generation Journal, September 1997, pp16& 17, authors, Hannah Hulme Hunter,
Karen Lake & Christine Knox.
