9 Cypress Essential Oil Benefits, Uses & Safety Tips

QUICK SUMMARY

Cypress essential oil, typically distilled from Mediterranean cypress (Cupressus sempervirens), has a fresh, woody aroma used in diffusion, diluted massage, and household blends. Laboratory and animal studies suggest antioxidant, antimicrobial, and other biological activity, but human clinical evidence for treating liver disease, infections, cold sores, varicose veins, or respiratory conditions is limited. Learn nine potential benefits, what the research actually tested, and how to use cypress essential oil more thoughtfully.

Cypress essential oil has a distinctive fresh, woody fragrance, and its potential benefits have attracted interest in natural wellness research.

The Mediterranean is well known for its distinctive aromatic plants, including the coniferous Cupressus sempervirens, or cypress tree. Cypress has a long history in traditional plant use, although the region’s longevity cannot be attributed to any one herb or essential oil.

History & Chemical Components

Cypress essential oil is steam distilled from the needles of the cypress tree Cupressus sempervirens. The oil is also referred to as Mediterranean or Italian cypress, named for the region where it is commonly found.

Not to be confused with blue cypress, or Callitris intratropica, which comes from the same family but is a very different plant cultivated in Australia. Each oil has unique constituents as well as distinctive properties and aroma.

This article will focus on Mediterranean cypress.

Major constituents reported in cypress essential oil include: (2)

• α-pinene
• carene
• limonene
• α-terpinolene

Today, cypress is used commercially in fragrances and shampoos. Trees translated as cypress are mentioned in Isaiah, although the precise botanical identity of ancient Biblical tree names is debated. The wood used for Noah’s ark is likewise not securely identified as modern Mediterranean cypress. Cypress leaves and cones have a long history in folk medicine for skin complaints, digestive discomfort, and other concerns, but traditional use does not establish clinical effectiveness. (1)

9 Benefits Of Cypress Essential Oil

I’m sure you’ve seen a lot of anecdotal evidence out there in the blogosphere that cypress oil is great for the bladder and urinary tract system – many parents swear by the fact that it has helped their children with enuresis (bedwetting). As a researcher, though, it’s important for me to note that there is no research to validate this in a clinical setting.

Family experiences can help generate research questions, but anecdotes cannot tell us whether an oil reliably treats bedwetting or whether symptoms improved for another reason. Persistent bedwetting deserves an age-appropriate evaluation rather than an untested oil protocol.

Cypress essential oil does not have an extensive body of human clinical research. Most of the findings below come from in vitro experiments, animal studies, or traditional use. Let’s look at what they do, and do not, establish.

1. Potential Liver-Protective Compounds

In 2007, researchers in Egypt isolated the compounds in cypress leaves and tested them on rat livers. (3) They discovered that these compounds protected the rats’ livers, thanks to their antioxidant activity. Antioxidants are compounds that help stave off the damage done by free radicals, which can cause oxidative stress. This is linked to disease and unhealthy aging.

This is intriguing preclinical research, but the experiment does not show that applying or inhaling cypress essential oil protects human liver function. The isolated compounds and the distilled essential oil are not necessarily equivalent preparations.

Application: For a pleasant aromatic massage, add 2-3 drops of cypress essential oil to 1 ounce of your favorite carrier oil in a roller bottle. This is a massage blend, not a proven liver treatment. 

2. Antioxidant and Enzyme Research

Cypress preparations have shown antioxidant activity in laboratory assays. (4) Some studies discuss flavonoids such as quercetin in cypress plant extracts, but these nonvolatile compounds should not be assumed to occur at meaningful levels in steam-distilled essential oil. (5)

Laboratory testing has also explored inhibition of butyrylcholinesterase (BChE), an enzyme involved in neurotransmitter breakdown. This is a research lead, not evidence that cypress oil prevents Alzheimer’s disease, improves memory, or protects the human brain.

Application: Diffuse 2 drops each of cypress, frankincense, and lime essential oil for a refreshing woody-citrus aroma. Diffusion is not a proven brain-protective treatment.

3. Antibacterial and Biofilm Research

Cypress oil has been shown to have a “significant” antimicrobial effect on several strains of bacteria, including E. coli. (5) This is in agreement with several studies.

It has other advantages as well. Biofilm are a group of microorganisms that are “stuck” to surfaces. Harmful bacteria in biofilm can be difficult to clear without the right cleansing agent but research shows that cypress oil can effectively clean it. (6)

Antimicrobial activity depends on the organism, oil composition, concentration, and experimental conditions. Laboratory findings involving biofilms or fungi, including Candida albicans, do not establish that a homemade cypress cleaner disinfects household surfaces or prevents infections. Use an appropriately registered disinfectant when reliable pathogen control is needed.

Application: Add a few drops of cypress and lavender essential oils to your kitchen cleaning solutions.

4. Preliminary Antiviral Activity

Cypress essential oil was part of a study out of Iraq that tried out various plant extracts and essential oils from the cypress family, as well as others, in treating Herpes Simplex-1. (7) These natural compounds were compared to acyclovir, a drug used to treat this type of viral infection. The researchers reported antiviral activity under laboratory conditions. Such comparisons do not demonstrate that cypress oil works as well as acyclovir in people.

These were laboratory findings, not clinical trials of cold-sore healing. Essential oils can irritate the lips and damaged skin; proven antiviral medicines remain important for people who need treatment.

Application: For routine lip care, consider our Soothing Lip Balm recipe as written. Do not add cypress oil to a cold sore or broken lip skin as an antiviral treatment, and do not share lip products during an outbreak.

5. Traditional Wound-Care Interest

Traditionally, cypress essential oil has been used to heal wounds. This may be due to the claim that it can constrict blood vessels, meaning it has the potential to help blood clot quickly when used on bleeding injuries. (8)

Cypress ingredients have also been used in commercial soaps. (9) That does not establish safety or healing benefits when essential oil is placed directly on an open cut. Clean minor wounds with water and use standard wound care; seek medical attention for deep, infected, or heavily bleeding wounds.

Application: For intact skin, cypress may be included in a properly diluted body-care blend. Explore our lotion bar recipes without treating them as substitutes for wound care.

6. Skin and Body-Care Applications

Cypress is included in some traditional and cosmetic approaches to oily skin, body odor, and acne. It also appears in aromatic deodorant blends. (10, 11) Evidence is insufficient to recommend it as a treatment for rosacea, cellulitis, or other diagnosed skin diseases. Cellulitis in particular requires prompt medical assessment.

Application:  Make a DIY toner by diluting 6 drops of cypress and 6 drops of lavender in half an ounce of 190-proof alcohol. Then slowly add half an ounce of witch hazel and 1 ounce of distilled water. Spritz on skin. Store in a cold place and discard after 1 month.

7. Botanical Herbicide Research

Do you love gardening but dislike the options you have for defending your plants against weeds and pests? Many of these options contain harmful ingredients that can be toxic to your health, especially if you are growing your own food.

Laboratory and experimental studies have investigated cypress essential oil for herbicidal, antifungal, and insect-related effects. (11, 12) That does not establish that it is harmless to people, pets, soil organisms, or desirable plants, or that a homemade mixture provides reliable weed control.

Application: Add 2-3 drops of cypress essential oil to our Homemade Weed Killer recipe.

8. Respiratory Aid

Cypress oil has traditionally been used in aromatic blends during colds and coughs, but there is little clinical research demonstrating respiratory benefits. 13 Its scent may feel pleasant, yet diffusion does not treat bronchitis, asthma, sinusitis, or respiratory infection.

We recommend you diffuse a small amount first if you have asthma or respiratory allergies to ensure it does not adversely affect you.

Application: Diffuse 2 drops each of orange, mandarin, and cypress essential oils when struggling with colds, coughs, and other minor respiratory issues.

9. Varicose Veins

Cypress oil is traditionally included in leg-massage blends for the appearance of varicose veins, but clinical evidence that it shrinks veins or corrects venous insufficiency is lacking. A gentle diluted massage may feel soothing, but avoid massaging a leg that is newly swollen, painful, red, or warm; these symptoms need medical evaluation.

Application: Create a 2% dilution (12 drops per 1 ounce of oil) with your favorite carrier oil and massage into your legs.

Cypress Essential Oil and Safety

Use these common-sense safety tips when using cypress essential oil, especially when trying it for the first time:

• Cypress essential oil should not be assumed safe to consume. For topical use, follow appropriate dilution guidance. Medicinal internal use requires product-specific evidence, dosing, and qualified supervision; avoid self-treating bleeding or clotting conditions.
• Store in dark glass to avoid oxidation.
• Some sources claim that cypress oil should be avoided during pregnancy but there is no research supporting this statement. However, you might want to avoid it while pregnant or breastfeeding to be cautious.
• Cypress oil can interact with respiratory issues as either an aide or an irritant. Use with caution if you have asthma or allergies.
• Avoid cypress oil that has oxidized because it can pose a greater risk of skin sensitization. You’ll know it has oxidized if the smell or color changes or it has expired.
• Do not give cypress essential oil internally to children without qualified, product-specific guidance. One drop per dish is not an established pediatric safety threshold.
• For children, consider age, respiratory sensitivity, oil identity, and exposure time before diffusion or topical use. A 1% dilution is not a universal guarantee of safety.
• Don’t consume straight out of the bottle, and don’t drink with water (remember oil and water do not mix).
• Do not casually ingest essential oils in water or neat (undiluted). Internal use of essential oils requires proper dilution, product quality, dosing knowledge, and safety guidance. Learn more about how to ingest essential oils here. The original 2-3-drop capsule suggestion is not an established safe protocol for cypress.
• Do not stay on cypress oil for an extended length of time. Ideally, you should rotate your oils every few weeks.
• Stop using it immediately if you experience any side effects.
• Use with caution if you take medications. Check with your healthcare provider first.

Cypress essential oil generally has a thin consistency and a fresh, woody aroma. It blends well with other woody or resin-based oils, such as frankincense or myrrh, florals such as lavender or geranium, and with the citrus family of oils.

This aromatic tree from the Mediterranean can be a useful addition to your essential oil cabinet for thoughtfully diluted body-care blends, massage, and diffusion. Its early antimicrobial and antioxidant findings are interesting, but stronger human studies are needed before making disease-treatment claims.
