The wild sweet violet, viola odorata, has a 'scent numbing' component
which dampens the smelling sense so that it seems that the scent has
quickly died. This was used in them thar olden days when the violets
were spread on the floor of churches, etc. and when crushed, their
odorific properties rendered the crusher oblivious to all the the
other smells that might have been around.
