my mother says calm to rhyme with pam..

as for palm oil.. well its not pure refined oil as we are more used to.. (corn oil or vegetable oil)

its more like butter (which is easily 'clarified" and can yeild a pure oil, but most westerns like the taste and characteristic of the 'milk solids' in butter, and rarely use clarified butter.

coconut cream is similar--its not pure oil either, but has coconut meat (suspended solids) in it..
coconut oil is sweet. but red palm oil is sharp (think of the succulent taste of a tomato.. or citrus fruit)

(you can get a similar taste to red palm oil by combining tomato paste and coconut oil.--sounds weird, taste good as gravy (with peanut butter for ground nut stew))

meanwhile getting back to hand/palm
there is also the hosta plant, who's latin name has a palm root--only with (edit, thanks to dr bill,) with a twist.. a metathesis, it's plantian.. (like plantain weeds)
(more editing..)
in checking the metathesis is an old one! these are from the american heritage dictionary, (with links too)

the PLANTAR of plantar warts (on the soles of your feet) is related to the PALM of the palm of your hand!--and to the palm tree..
