A diffuser 1 for diffusing essential oil into a room using steam comprising a housing 2, a liquid container 6 in the housing, a heater 11 for heating the liquids in the container 6 to vaporize it, and a support 5 for holding volatilizable-substance matter 20 above the liquid container. For convenience, the volatilizable-substance matter 20 is in the form of an aroma packet, having upper 22 and lower 23 cellulose tissue webs, holding between them some dried plant material, for example lavender blooms. The webs are sealed together at their edges by a rim, which is sized to fit the support of the diffuser.
