Marjoram essential oil is popular for a couple reasons. It has some amazing benefits. It is antibacterial, antifungal, and even antiviral; and it is great at keeping bugs away.
Marjoram Essential Oil Properties
The botanical name for marjoram is Origanum majorana. You may see Majorana hortensis as well.
Marjoram is sometimes called sweet marjoram so if you see that name, don’t worry, it’s the same thing. But if you see wild marjoram, you should know that might actually be oregano. Its botanical name is Origanum vulgare. And Spanish marjoram is different too. Its botanical name is Thymus mastichina and is part of the thyme family.
Color and smell
The oil is typically clear and smells like the herb. So think of it as warm, woody, spicy and a little like nutmeg. It’s really nice.
What is in the oil?
The main compounds in marjoram oil include terpinen-4-ol and gamma-terpinene. Other compounds reported include thymol, thujanol, alpha-terpinene, beta-terpinene, linalyl acetate, terpinolene, sabinene, and linalool.
Marjoram Essential Oil Benefits
The benefits of marjoram essential oil show it can neutralize free radicals in vitro. And it can kill bacteria, fungi, viruses, and kill and repel insects (like lice), spiders, ticks, and mites.
It is antioxidant in vitro
The oil has shown strong radical scavenging and antioxidant benefits in this 2011 study and this 2009 one. In the 2009 study, several oils were tested including black pepper, clove bud, and ginger. While marjoram was not the most powerful, it did have good antioxidant benefits.
Side note: clove bud, ginger and cinnamon leaf were the most antioxidant oils tested.
It’s good against lice
This 2004 study tested 50 essential oils on human lice. And the results were compared to delta-phenothrin and pyrethrum (common chemicals used for lice). Would you believe marjoram, eucalyptus, pennyroyal, and rosemary were stronger than the chemicals? It’s true! And even the vapors of the oil were effective.
How wonderful?! But that’s not all. This 2009 study found marjoram oil killed drug-resistant lice too. And it inhibited the eggs from hatching.
So marjoram oil is definitely a great oil to get rid of lice fast.
It’s also insecticidal
Well, if marjoram is good at killing lice then it is an excellent insecticide.
This 2007 study proves it too. It tested 34 essential oils on houseflies and found oregano, pennyroyal, basil, and marjoram were the strongest. And they kept the flies away too.
It repels ticks too
Marjoram oil also has moderate acaricidal benefits, as this 2017 study shows. It tested oils like bergamot, citronella, clove bud, lavender, and marjoram on ticks. And marjoram had good repellent activity, but it did not come close to clove bud’s.
It is antibacterial
Marjoram oil is one of the best antibacterial essential oils. In one study, 0.25% and 0.5% blends killed multidrug-resistant bacteria. That is powerful!
In a more recent study, marjoram was more effective against E. coli and Salmonella enteritidis than synthetic antibiotics. Powerful, indeed!
It is also antifungal
This 2015 study showed marjoram essential oil also had strong antifungal benefits too.
It is antiviral
This is not a common benefit by any means. But it is a testament to the antimicrobial nature of marjoram oil.
A 2009 study tested oils like marjoram, lavender, peppermint, and sage against two viruses: Herpes simplex type-1 and parainfluenza type-3 (PI-3). The study found most oils including marjoram had strong antiviral benefits.
Marjoram Essential Oil Uses
You can add marjoram to your diffuser for a woody, spicy smell. It’s nice and you can mix it with other spicy, woody and citrus oils too. So try it with bergamot, black pepper, cypress, eucalyptus, frankincense, lavender, lemon, peppermint, tea tree and thyme essential oils.
You can use it on your skin too. But you should do a patch test first to make sure you are not allergic or sensitive to the essential oil.
And you saw how antimicrobial the oil is, so use it to treat your bacterial, fungal and viral skin infections. Oh and add it to your cleaning sprays too.
Finally, talk to your doctor before using this oil especially if you are pregnant, nursing or using special medications.
