Uses of aromatherapy fragrances can be used for so many things, they can hide unwanted smells, of just to stimulate your senses. In fact some real estate agents advise their sellers to use clary sage or lemon essential oils in their home before potential buyers arrive to put them at ease. If you are trying to uplift your study or office, to get rid of the stuffy feeling, then I would try some of these oils. Basil, rosemary, bergamot or lemon.
Using a vaporizer or burner in the living / lounge room can add a fragrance that can help to prevent ill-health, can balance your emotions and of cause disguise those unwelcome smells that can occur. In the bedroom for a peaceful night sleep try burning, Rose, neroli and lavender oils to create some atmosphere. If you are having visitors and your spare room hasn't been used for awhile try using lavender to get rid of that musty smell.
To get rid of insects try putting Tea tree, eucalyptus, or lemongrass in a vaporizer. And to keep insects off your clothes in your cupboard, place a drop of oil onto a cotton ball and put in your draw or cupboard. If someone is sick in the home, try vaporizing Tea tree, bergamot, lemon and lavender, all these essential oils have excellent antiseptic properties. You can also wipe down your bathroom using a damp cloth with a few drops of one of these essential oils on it to disinfect it. If you're having a party for a "feel good" atmosphere you could use clary sage or jasmine. Or for a Big Festive effect, blend oils like frankincense, sandalwood, cinnamon or orange.
If you want to make a spray bottle for, disinfectants, air fresheners or insect repellent these are all make the same but different essential oils are used for each. Put 250mls of boiled water (cooled) into a spray bottle and add the blend of oils which you want to use, put the lid on shake and keep in the fridge until you want to use it and then just spray the mist into the air. My favorite air freshener is 7.5mls rose, 2.5mls orange and 2.5mls clove, this gives a lovely floral smell, or just creates your own. My favorite disinfectant I use around the home is, 5mls eucalyptus, 2.5mls tea tree oil, 2.5mls of lemon, 1.5mls clove and 10 drops of cinnamon. For our Insect repellent we use the following essential oils, 5mls eucalyptus, 1.5mls of citronella, 1.5mls of geranium, and 10 drops of peppermint, I find that that blend keeps the insects away.
