Peppermint flavour (7)

I believe the answer is:

menthol

(Other definitions for menthol that I've seen before include "Soothing substance from peppermint" , "medicinal compound" , "Substance from peppermint oil used as flavouring." , "Peppermint camphor" , "Peppermint oil derivative" .)

I've seen this clue in the Sydney Morning Herald.
