Eucalyptus (Eucalyptus globulus). A good essential oil to use for asthma, sinusitis, colds and flu symptoms. It can clear the head and be uplifting. Also good to use for aches and pains. Use 4 - 5 drops in a warm bath and agitate the water to disperse the oil.
Also good for cellulite when used in a massage along with body brushing after a shower.
