Sandalwood is a good oil to use when you want to release pent-up anger and frustration.  You can also use the following blend of oils:  4 drops lavender, 3 drops geranium, 3 drops rosewood, 3 drops rosemary, 2 drops tangerine, 1 drop spearmint, 2 drops tansy, 2 drops blue chamomile and 1 oz pure vegetable oil.  Apply to back of neck, wrist and over the heart area.  Source:  Aromatherapy A-Z by Connie and Alan Highley and Pat Leatham.
