Two flavours/scents I can’t abide are cloves, and lavender.
The new toothpaste, Crest, has the distinct flavour of cloves, which is odd as that taste is associated with toothache.
The shower gel, meanwhile, has a nasty, acrid, piercing top-note of lavender.
My bathroom hates me.
UPDATE: It turns out that the active ingredient in clove essential oil is eugenol, and that harsh top note in the lavender fragrance is probably camphor, and both are hepatotoxic, which means they're bad for the liver. So that, boys and girls, is most likely where my dislike for those two compounds derives from. Isn't that interesting?
