Which essential oils should be avoided by hypertensive individuals because they act like a salt substitute?

• A. Rosemary, sage, and thyme
• B. Basil, clary sage, fennel
• C. Cedarwood, sandalwood, patchouli
• D. Ylang-ylang, rose, jasmine

Answer: (A)

The main idea is that some essential oils can stimulate the nervous system and cardiovascular system enough to affect blood pressure, so hypertensive individuals should avoid those that are particularly activating. Rosemary, sage, and thyme are known for their strong stimulating properties; when used in aromatherapy or massage, they can increase circulation and alertness and may raise blood pressure in sensitive people. Because of this potential effect on blood pressure, these oils are generally avoided or used with extra caution in clients with hypertension. The other oils listed tend to be more calming or neutral in their cardiovascular impact, so they do not carry the same warning for hypertension.
