Excerpt taken from: How To Lower Blood Pressure Naturally With Essential Oil.

The following is a list of essential oils that have historically been used to help regulate high blood pressure. All the essential oils mentioned here can easily be incorporated into daily life through inhalation, topical application and massage.

1. Lavender (Lavandula angustifolia)

There are several oils to choose from; however, those that are immediate favorites among essential oil enthusiasts include Lavender (Lavandula angustifolia) because of its high content of esters and alcohols, chemically speaking. Its sweet, floral aroma is very calming and works as a general tonic on the nervous system. In addition to this, Lavender’s soothing effect on the body as well as emotions makes it a favorite in the treatment of nervous disorders.

2. Sweet Marjoram (Origanum marjorana)

A second favorite is Sweet Marjoram (Origanum marjorana), which is high in monoterpenols and serves as a balancing tonic that is calming to the mind. It is great for chronic lethargy and nervous exhaustion. Sweet Marjoram’s warm, spicy scent is quite relaxing and soothing.

3. Cypress (Cypress sepmervirens)

Another essential oil that doesn’t get quite as much fanfare is Cypress (Cupresus sepmervirens), which strengthens the vascular system and increases circulation while at the same time supports the detoxification of the lymphatic system. Quite beneficial indeed!

4. Helichrysum (Helichrysum italicum)

Helichrysum (Helichrysum italicum) is a powerhouse all by itself as a natural anti-inflammatory; it improves circulation and cleanses the blood.

5. Ylang Ylang (Cananga odorata)

Finally, Ylang Ylang (Cananga odorata) which is high in sesquiterpenes, offers a calming and supportive effect to the nervous system while easing stress and tension that leads to high blood pressure. Like several of the previous essential oils mentioned, Ylang Ylang is high in alcohols and esters, which makes it rich in qualities such as promoting sleep and soothing agitation. Its sweet floral scent is quite intense, though, so you will not want to add too much of this oil to your blend.

Kurt Schnaublet, PhD, in his book “Advanced Aromatherapy,” states that even in the minutest amounts, Ylang Ylang has a noticeable and instantaneous effect on heart palpitations. Dr. James Howenstein, MD, recommends rubbing a single drop of Ylang Ylang oil between the fingertips and inhaling for one minute for hypertension. This can be repeated as needed.

There are many, many more essential oils to choose from. It is important, however, to check with your doctor before using essential oils. There are some medical conditions, such as prescription medications and pregnancy that contraindicate the use of some essential oils.
