Take lavender oil for example. It works for insomnia. A drop or 2 on the pillow helps you relax and sleep. Marjoram is an even more effective sedative.

A blend of lavender oil and geranium is even more effective than lavender oil alone. Add 1 drop of geranium oil and 1 drop of lavender oil to 1 teaspoon of any CarrierOils, massage your feet with them and see how relaxed you feel in a few minutes. Works on fretful kids too.

chamomile essential oil is a mild relaxing oil which is suitable for children. 1 drop of chamomile oil in 1 teaspoon of any suitable CarrierOil added to a kid's bath helps relax a stressed out kid. Massaging the chamomile oil (in carrier oil) on an upset tummy helps relieve a baby's uncomfortable stomach. (Temporary measure for mild discomforts only. If this is a regular situation, or you suspect something is wrong, bring the baby to see a doctor immediately.)

neroli is another stress busting oil. If you have 'butterflies in your stomach' before an important meeting or event, try a little neroli oil on your wrists. (dilute 1drop neroli essential oil in 1 teaspoon carrier oil first before use). It smells like a beautiful top quality cologne.

rose oil is another oil for stress relief. One of the sweetest scents around.
