Can essential oils lower blood pressure?

Many people use essential oils for high blood pressure (hypertension). However, there is little evidence yet that essential oils can lower blood pressure. Since hypertension can lead to heart attack or stroke, it is important not to rely on essential oils alone as a remedy. Your doctor may recommend lifestyle changes and medications for high blood pressure. Talk to your doctor before adding essential oils to your treatment plan.

What oils can be used for hypertension?

Bergamot

In a small study of 52 participants, researchers tested whether inhaling an oil mixture containing bergamot could lower blood pressure. The blend also included lavender and ylang-ylang. Based on their results, the researchers concluded that essential oils may help reduce high blood pressure.

Citronella

People traditionally use citronella oil as a mosquito repellent, but it can also help heart health. A 2012 study published in the journal Health Research

, reports that inhaling citronella vapor can lower blood pressure, heart rate, and breathing rate.

Clary sage

A 2013 study included 34 participants with urinary incontinence. Scientists found that clary sage oil reduced participants' heart rates during urodynamic examinations. It's important to note that clary sage oil—unlike clary sage oil—contains a compound called thujone, which can increase blood pressure.

Incense

Frankincense essential oil is a popular component of Eastern medicine. In addition to its anti-inflammatory properties, it can also help combat anxiety and similar problems. These effects may reduce high blood pressure.

Lavender

Lavender is one of the most popular essential oils for enhancing relaxation and reducing stress and anxiety. Researchers found that a mixture of oils, including lavender, could reduce high blood pressure in participants who inhaled it.

Neroli oil

Researchers have found that neroli essential oil mixed with lavender, ylang-ylang and marjoram can reduce stress and blood pressure in people with prehypertension and hypertension.

Rose

Rose oil has a calming effect. Applying rose oil to the skin can reduce blood pressure, heart rate, breathing rate, blood oxygen saturation levels and skin temperature.

Marjoram

Researchers observed changes in the blood pressure and heart rate of participants who inhaled sweet marjoram essential oil.

Valerian

Valerian is an excellent relaxant that promotes sleep and promotes calm in people and pets. Scientists note that the essential oil can be used to treat mild mental stress and improve sleep.

Ylang-ylang

Researchers have used ylang-ylang essential oil in combination with other oils to effectively lower blood pressure. A small 2013 study reported that the aroma of ylang-ylang may have a sedative effect that significantly lowers blood pressure.

Introduction

Essential oils (EOs), including citrus oils, find a wide variety of uses, including for human health. Lemon essential oil, which is similar in composition to orange essential oil (70% limonene, 2-6% citral, small amounts of geranyl acetate, myrcene, citronellol, etc.) is used as a sedative and hypotensive agent. The effectiveness of this use of essential oils increases when combined with psychotherapy methods. The latter is the basis for studying the possibility of using orange essential oil in combination with a psychorelaxation program as a stress-limiting agent for people whose work is associated with psychophysical stress and risk. These include employees of the Ministry of Emergency Situations.

The purpose of this work is to study the possibility of improving the psychophysiological state of employees of the Ministry of Emergency Situations using orange essential oil and a psychorelaxation program.

Objects and Methods

The study was carried out on 19 male employees of the Ministry of Emergency Situations aged 25-40 years. A similar group of the same size served as a control. The subjects in the control group were at rest for 20 minutes with the psychorelaxation recording turned on. The subjects of the experimental group were in the same room for the same time with the same psychorelaxation recording turned on and the evaporation of orange essential oil into the atmosphere, in which limonene predominates (92.0%). Myrcene (2.1%) and a number of minor components are present in much smaller quantities.

The concentration of volatile components of EOs in the room atmosphere was 1 mg/m3. Testing was carried out before and after procedures.

To assess the effect of the procedures on the cardiovascular system, heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (BP) were measured. To assess the effect of EM on the nervous system, we used the SAN test, a proofreading test in the letter version, and a test for memorizing 10 words. The obtained data were processed statistically using paired t - Student's test.

Results and discussion

Initially (before aroma exposure) ADS in both groups did not have significant differences and was within the high norm according to JNC6 (Table 1). ADD was initially lower in the control group (optimum) than in the experimental group (within the high norm according to JNC6). Heart rate is within normal limits. The impact of the psychorelaxation program (control) was accompanied only by a tendency towards a decrease in ADD.

Table 1 Effect of relaxation with orange essential oil on blood pressure and heart rate

In the experiment (exposure to orange essential oil against the background of a psychorelaxation program), a significant decrease in ADP and a tendency towards a decrease in ADP were observed. As a result, blood pressure in the experimental group became significantly lower than in the control group, and heart rate remained significantly higher.

An assessment of the psycho-emotional state of the subjects using the SAN test shows that initially in the experimental group the indicators of vigor and performance were significantly higher and the indicators of tension were lower (Table 2). After the psychorelaxation program, a significant decrease in tension was observed.

Table 2 The effect of relaxation with orange essential oil on the psycho-emotional state (SAN test)

In the experiment (the effect of orange essential oil against the background of a psychorelaxation program), a significant improvement in the general state and well-being was observed. The differences between the experimental and control groups in the final state consisted of significantly better values ​​of general condition, well-being, mood and vigor in the experimental group.

An assessment of mental performance (correction test, letter version) shows that initially the groups generally do not have significant differences in speed of work and only a tendency towards a greater number of errors in the 1st minute of the test in the control group.

Table 3 The effect of relaxation with orange essential oil on mental performance (proofreading test, letter version).

After the psychorelaxation program (control), no significant dynamics of indicators were observed. After exposure to orange essential oil against the background of a psychorelaxation program (experiment), a tendency was noted to decrease the speed of work in both minutes of the test and a significant increase in the number of errors in the 1st minute of the test. As a result, the final speed of work at the 1st minute of the test in the experiment turned out to be significantly lower than in the control.

Thus, we can only talk about a slight inhibitory effect of orange essential oil on mental performance.

Assessment of short-term memory (10-word test) shows that there is no significant difference between the groups at baseline. As a result of psychorelaxation and aroma-psychorelaxation procedures, no significant dynamics in short-term memory indicators were found (Table 4).

Table 4 Effect of relaxation with orange essential oil on short-term memory

Conclusions:

Aromapsychorelaxation procedure with orange essential oil:

-has a moderate (significant for ADS and tendency for ADD) hypotensive effect.

-reduces (at the level of a trend) the speed of work and increases the number of errors in a proofreading test.

-slightly (tendency) improves the psycho-emotional state mainly due to indicators of general condition and well-being.

- has virtually no effect on short-term memory.

How effective are essential oils for high blood pressure?

Overall, research on essential oils for treating high blood pressure is limited. A person should not use these oils as a substitute for prescribed medication.

In 2006, researchers assigned 52 patients with hypertension to three groups: an essential oil group, a placebo group, and a control group. Those in the essential oil group inhaled a mixture of lavender, ylang-ylang and bergamot once a day for 4 weeks. The researchers measured the blood pressure and pulse of all participants twice a week. The scientists noted significant differences between the groups, suggesting that inhaling essential oils may reduce psychological stress responses, serum cortisol levels, and blood pressure.

In 2012, scientists conducted a similar study. This time, the purpose of the study was to examine the effects of essential oil inhalation on blood pressure and salivary cortisol levels in 83 people with prehypertension or hypertension. Those in the essential oil group inhaled a mixture of lavender, ylang-ylang, marjoram and neroli for 24 hours. Afterwards, participants' daytime blood pressure and salivary cortisol levels decreased significantly compared to the placebo and control groups.

However, in 2014, researchers found that exposure to essential oil vapor for more than 1 hour may be harmful to the cardiovascular system.

Massage mixtures

Aromatherapy massage through the skin has a beneficial effect on the functioning of the circulatory system and the condition of blood vessels. The room should be warm enough - up to +23 degrees. Before the procedure, it is important to take a warm shower so that the skin becomes clean, slightly steamed and opens its pores. After the massage, for maximum effect, it is better not to swim for 10-12 hours. This will help maintain a normal state longer.

Important: essential oils for massage must be diluted in a base oil, such as olive or almond, before applying to the skin.

Example of a massage mixture

For 15 ml almond oil (base)

• 3 drops black pepper;
• 3 drops rosemary.

Aromatic baths

Aromatic baths have a more powerful effect on the body than the first two methods separately. In this case, beneficial esters are not only inhaled, but also absorbed through the skin. In this way, a hypotensive person significantly improves his condition, while relieving stress and relaxing. For treatment, baths are usually carried out every other day, as a preventive measure - 1-2 times a week.

The optimal water temperature for an aroma bath is considered to be up to 38 degrees. At higher levels, beneficial substances evaporate. It is undesirable for the volume of oils added to the bath to exceed 10-15 drops. Dosage for the first session – 3-4 drops. If well tolerated, the proportion of substances is gradually increased. There is no need to combine many scents at the same time. It is better to choose from 2 to 4 components.

Important: Esters that increase pressure and any others do not dissolve in water in their pure form. They need to be added to a small amount of a natural emulsifier (honey, salt, heavy cream or sour cream). The resulting mixture is distributed in the bath.

Are essential oils safe?

Essential oils do not pose much of a risk if people use them as intended. However, precautions should be taken:

Do not ingest essential oils—use them externally only.

Always dilute essential oils in a carrier oil before applying them to your skin. Undiluted oils may cause skin irritation.

People with asthma, migraines, or headaches should avoid inhaling certain essential oils.

Avoid using essential oils close to your eyes. If oil gets into your eye, rinse it thoroughly with water and consult a doctor.

Use reputable brands of essential oils and make sure they haven't expired.

Keep essential oils away from children and animals.

When atomizing or diffusing oil preparations, consider other factors. Some oils may be harmful to pregnant women, children and animals.

If a person ingests an essential oil, side effects may appear within 30 minutes, although they may take up to 4 hours. These unwanted effects may include:

• skin irritation
• eye pain, soreness, or irritation
• persistent cough
• nausea and vomiting
• drowsiness
• shallow breathing
• to whom

Does the quality of oils affect the effect?

Aromatherapy gives the desired positive results only when used correctly using natural plant extracts. Only natural extracts from plants without additional impurities in the composition will be effective for hypertension.

The composition of the oil obtained using steam distillation is considered to be of high quality; only this method guarantees the highest concentration of the natural components of the plant. Products reconstituted from dried raw materials will be useless, especially if additional components are added to their composition. This technology deprives the plant of its healing properties and makes the extract from it exclusively perfume.

You can distinguish a real essential oil by the following characteristics:

• dark glass bottle;
• presence of a Latin name;
• comprehensive information about the method of obtaining the product;
• commercial name in the original language.

It is worth paying attention to the expiration date of essential oils planned for use for hypertension. It is advisable to purchase aromatic medicines for the treatment of high blood pressure in pharmacies or special health stores.

Use of essential oils during pregnancy or children

The use of essential oils by pregnant women or children is highly controversial. There is concern that in pregnant women, the oils used may penetrate the placenta and affect the fetus. In addition, inhaled molecules of these oils can pass to the fetus through the blood. However, some essential oils may be safe to use during pregnancy. Pregnant women should consult their doctor before trying any essential oil.

Children have a greater risk of toxicity from essential oils than adults. Even 2 milliliters can cause serious poisoning in infants.

The healing powers of essential oils

Aromatherapy has been practiced since ancient Egypt.
Nowadays, the art of healing with the help of fragrant oily liquids is experiencing a rebirth. Oils and plants with a strong specific odor are used to restore health in many ailments. What are oily esters? These are natural volatile substances produced by cultivated and wild plants. Rich incense is the result of a significant presence of essential substances, which contain:

• Phenols.
• Ketones.
• Alcohols.
• Aldehydes.
• Esters.

First of all, the inhaled aroma enters the limbic structure, the person begins to feel different emotions, depending on the ethereal scent used. Molecules of aromatic oils are able to penetrate not only through the olfactory organs, but even through the pores of the skin.

When used correctly, essential substances can bring invaluable benefits to the human body, as they help improve the functioning of many vital organs and systems. They have the following therapeutic properties:

1. Sedative.
2. Antifungal.
3. Antibacterial.
4. Antiviral.
5. Antiseptic.

Despite the amazing capabilities of essential oils, their illiterate use can harm the body, so doctors advise refraining from self-medication without first consulting an aromatherapist.

Contraindications to the use of aromatic oils

It is worth emphasizing that natural essential oils practically do not provoke side effects, since they do not contain harmful components such as protein, nitrogen and sulfur. Experts explain the manifestations of episodic tearfulness or slight redness of the skin as a specific reaction of the body to aromatherapy. Also, oils do not provoke complications, and some unpleasant manifestations may indicate hidden diseases.

Despite the positive advantages of aromatic liquids, it is better to use them under the supervision of an experienced specialist who will professionally evaluate the therapeutic result, as well as the body’s susceptibility to these substances.

If certain factors are present, you should refrain from treatment with aromas, for example, during pregnancy (especially avoid dill and marjoram oils). For patients with epilepsy, lower dosages of aromatic substances are recommended.

How to choose the right aroma oils

Only high-quality, natural-origin essential substances have real healing capabilities for diseases. In order not to make a mistake in purchasing, doctors recommend focusing on the following nuances:

1. Real fragrant oils are sold in dark glass bottles. This way they are more reliably protected from sunlight.
2. The commercial name is always in the original language.
3. The tag must contain information about the product.
4. The shelf life and favorable storage temperature are indicated.
5. The bottle always has a built-in dropper.
6. Seek help from aromatherapy only after undergoing medical consultation.
7. It is better to buy essential products on the official websites of the manufacturer.
8. Avoid accidental contact of the fragrant substance with the eyes. If this happens, use a cotton swab soaked in vegetable oil to remove it (water is not suitable for this, as it is not capable of dissolving essential substances).
