"Hyssop is a quintessential cleanser, enabling a clarity of spirit and recognition of the divine beneficent power in the universe," writes aromatherapist Valerie Ann Worwood in Aromatherapy For the Soul.
She also says the emotional benefits of hyssop essential oil (Hyssopus officinalis) are to encourage awakening, acceptance, fulfillment, encouragement, direction, balance, and harmony.
Hyssopus officinalis is high in pinocamphone, which might be toxic in large doses. For this reason, use this essential oil only in small amounts.
A gentler and safer chemotype of hyssop is available — Hyssopus officinalis var. decumbens — which doesn't contain much pinocamphone. Know which type you are buying.

Aromatherapy: A Complete Guide to the Healing Art: Hyssop supports the respiratory and digestive systems. The essential oil also eases grief, fear, oversensitivity, and hysteria, while improving mental clarity.
Aromatherapy For Healing the Spirit: In Traditional Chinese Medicine hyssop is hot and stimulating and best used in moderation. This essential oil strengthens the lungs and the defensive Qi and may help improve poor vitality and breathlessness. Hyssop also strengthens the spleen-pancreas and warms the digestion, meaning the oil may help relieve appetite loss, slow digestion, and abdominal bloating.

For bruises: Use a cold compress with a few drops of hyssop or add the essential oil to a carrier oil and rub gently over bruise several times a day.
