Eucalyptus trees produce leaves and flowers that share a sweet, camphor-like aroma. Eucalyptus essential oil, which has been used in herbal medicine as an antiseptic and stimulant, carries the same fragrance. Making a simmering potpourri out of eucalyptus will freshen your environment with this scent.
Fill the nonstick saucepan with the distilled water, eucalyptus leaves and lemon grass. You can obtain these fresh botanicals via your local botanical nursery or through an online retailer. Alternately, you can use clippings from your own garden, if possible.
Set the temperature on a stove burner to its lowest setting.
Let the contents of the pot simmer on the stove's lowest setting for approximately 45 minutes at a time to release the smells of the eucalyptus and lemon grass.
Add up to five drops of essential oil of ginger to the simmering pot to add an under-note to the potpourri scent.
