Some of the most common and easiest to find incense and oil fragrances are these:
Amber - it stimulates the body self-healing capabilities. I always use it when doing Reiki
Eucalyptus - Good for respiration. Also used for purification and spirituality
Jasmine - Antidepressive, afrodisiac, and against insomnia. It\'s a pretty strong fragrance, so not everybody may like it. Good for dreams and visions.
Lavander - Calming, against headache, stimulates good health
Lemon - Gives strength but it\'s calming at the same time. Purifies blood and is a tonic.
Honeysuckle - Self-esteem, good for digestion problems and may be of use to lose weight
Mint - For clarity, can be used for respiratory problems, asthma, bronchiti, colds, flu. Good for upset stomach and headaches as well
Orange - Happiness. Against colds, depression. Used to create a pleasant and positive environment.
Pine - Against negativity, helps respiration
Rosemary - this needs a whole new post!
Rose - For harmony and love. Very good in curing scars, can be applied directly on the skin.
Sandalwood - Against depression, used for healing, spirituality and is afrodisiac
Ylang Ylang - Calming, promotes feeling of peace, and good against rage, anciently used as afrodisiac
