Aromatherapy

Area of Science:

• Complementary and Alternative Medicine
• Clinical Nursing
• Pharmacology

Background:

• Aromatherapy is increasingly used for patient well-being.
• The specific efficacy of different lavender species in clinical settings requires further investigation.
• The role of placebo versus active therapeutic effects in aromatherapy remains a subject of debate.

Purpose of the Study:

• To compare the therapeutic effects of two different lavender essential oils on emotional and behavioral stress in post-cardiotomy patients.
• To evaluate whether topical application of lavender essential oils offers benefits beyond placebo, touch, or massage.
• To investigate potential differences in efficacy between two distinct lavender species.

Main Methods:

• A randomized, double-blind trial was conducted.
• Twenty-eight post-cardiotomy patients received topical application of one of two essential oils from different lavender species.
• Emotional and behavioral stress levels were assessed pre- and post-treatment over two consecutive days.

Main Results:

• The two lavender essential oils demonstrated different therapeutic effects.
• One lavender oil was found to be almost twice as effective as the other in reducing patient stress.
• These findings suggest a specific therapeutic action of lavender essential oils.

Conclusions:

• The study disproves the hypothesis that aromatherapy's effectiveness is solely due to placebo, touch, or massage.
• Different species of lavender essential oils may possess distinct therapeutic properties.
• Topical application of specific lavender essential oils shows potential as an adjunct therapy for stress reduction in post-cardiotomy patients.
