Ask an Aromatherapist: Can Essential Oils Help with High Blood Pressure?

Research on the aromatic compounds in essential oils shows that there are numerous molecules that are hypotensive or promote lowering of blood pressure. Let's look at just a few of these aromatic compounds and see how we can incorporate these essential oils into products.

The ester benzyl benzoate is an example of an aromatic molecule that has been shown to have an inhibitory effect on aniotensin II induced hypertension. (1) The compound is found in oils such as Peru balsam (Myroxylon balsamum var. pereirae) essential oil (59-86%), jasmine (Jasminum grandiflorum) absolute (15 -24.5%) and ylang-ylang (Cananga odorata var. genuina) essential oil (4.3 - 14.9%).

Cedrol, a sesquiterpenol found in cedarwood (Juniperus virginiana) has been shown to lower blood pressure when inhaled. (2,3)

Linalool, a monoterpenol found in over 200 essential oils such as lavender (Lavendula angustafolia), bergamot (Citrus bergamia) , coriander (Coriandrum sativum), and bergamot mint (Mentha citrata), has a sedative effect and is also hypotensive. (4, 5, 6)

The major component of tea tree (Melaleuca alternifolia) , terpinene-4-ol, also found in sweet marjoram (Origanum marjorana) has hypotensive effects. (7, 8)

There are additional compounds but many commonly used essential oils can have a beneficial hypotensive effect given their aromatic profiles.

How to use these oils in a blend:

The hypotensive benefits of these compounds can be enjoyed aromatically or topically. A diffuser blend or aroma inhaler work beautifully or a massage oil or lotion or bath oil/salt would be wonderful as well. It's best to look at the individual and decide which is the best option. An inhaler is great for on the go or work or in circumstances where a diffuser can't be used. A massage oil or lotion is a great way to couple tension soothing touch with aromatherapy and baths are always a relaxing option. Since there are many oils with hypotensive aromatic compounds one can choose from a variety of aromas from woodsy to floral. Here are a few ideas:

Aroma inhaler: Use 15-20 drops total in an aroma inhaler. Try blending bergamot (8 drops), bergamot mint (5 drops), and coriander (2 drops) to create a fresh uplifting aroma with linalool rich oils. Or try cedarwood (3-5 drops) combined with lavender (10-12 drops), and a drop of ylang-ylang for a floral-woodsy aroma. Inhale as needed throughout the day to promote a sense of calm.

Relaxing lotion: Bergamot is very phototoxic so it is NOT a great choice for a lotion that will be used on an area that gets sun. But there are many other essential oils to choose from. Aim for a 2% blend which is 10-12 drops per ounce for adults. If you are blending for an elderly or frail person aim a 1% dilution is appropriate (5-6 drops of essential oils per ounce of carrier).

I like using ylang-ylang to soothe and calm but more than a drop or two can be very strong and cause headaches. Here are a few ideas for a relaxing lotion: To one ounce of unscented lotion or carrier oil (such as jojoba or fractionated coconut oil) add 2 drops of cedarwood, 1 drop of ylang-ylang, 4 drops of lavender, and 3 drops of orange. The orange, in addition to smelling awesome, contains d-limonene which acts as a skin penetration enhancer to help the hypotensive aromatics get absorbed more readily. For a more herbal, clean smelling blend try a 1 drop of sweet marjoram or thyme linalool, 5 drops of lavender, and 4 drops of orange. These blends would also be great in a roller ball. I like to make a 30 ml (or one ounce) blend in a stock bottle and transfer 10mls into my roller ball. Roller balls are great for on the go and can be easily to the neck, wrists, or as desired.

So yes the aromatic compounds in essential oils do have hypotensive effects and can be used to help promote relaxation and soothe the nervous system. As always do check for allergies and contraindications with medications and supplements before using essential oils and follow the advice of your health care practitioner.
