Can Essential Oils Help Circulatory Conditions?

What blood looks like inside a vessel

Let’s start with cardiovascular diseases (CVD) as they are one of the top causes of death worldwide. One metadata study reviewed the effects of essential oils on risk factors of CVD which include hypertension (high blood pressure), diabetes, fatty liver and an abnormally high amount of lipids in the blood (dyslipidemia). Evidence showed that essential oils improved lipid balance, liver function, reduced blood pressure, the onset of diabetes, relaxed blood vessels and inhibited blood clots. The studies reviewed included those on animals and humans. The study concluded that essential oils may be promising therapeutic agents for CVDs. https://www.researchgate.net/publication/327983319_Essential_Oils_and_Factors_Related_to_Cardiovascular_Diseases
 
In another systematic review, herbal essential oils were shown to reduce coronary artery disease, heart attack, abnormal heart rhythms, heart failure, vascular diseases and many others. However, these studies were conducted in mice, rats and rabbits. https://www.heighpubs.org/hda/pdf/ida-aid1016.pdf
 
In a third systematic review, the cardiovascular activity of essential oil constituents was studied. These studies were conducted on animals as well. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6151533/
 
Although results of animal testing aren’t an indication that the same result will be obtained in humans, it can suggest possibilities for further research.
 
One study measured the blood pressure of subjects at home that inhaled a blend of lavender, ylang ylang, marjoram and neroli. The experimental group’s blood pressure was significantly reduced, compared to the placebo and control group. The effects were seen in as little as ten minutes. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3521421/
 
Another study used inhalation of marjoram essential oil and observed that blood pressure and heart rate decreased in this group but not the control group. https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0172841
 
A study was conducted on 40 patients who had open heart surgery and after inhaling lavender, their heart rate and blood pressure was significantly reduced. This is important since many patients experience abnormal or high heart rates and high blood pressure due to the stress and pain of their surgeries. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5423266/
 
For hemorrhoids, myrtle essential oil was reviewed and found to significantly improve bleeding, pain, irritation and itching, even in patients who did not respond to current chemical ointments.
