Here is the question we asked our readers:

What essential oil is your least favorite? Here is what we found out.

The answers to this question all seemed to relate to the smell of the essential oil or how the body reacted to the aroma. That makes sense because each and ever essential oil offers so many positive benefits that what it really comes down to is the smell or your reaction to the essential oil. Maybe the smell even reminds you of an unpleasant memory.

Worst Smelling Essential Oils - Least Favorites

OK, so the results REALLY SHOCKED ME!!

There were so many different answers that I can't just make this the top 10 worst-smelling essential oils because I have a list of over 45 oils that were mentioned negatively. Oils from A-Y (Angelica Root to Ylang Ylang)

What do these findings suggest? To me, it indicates that smell is such an individual preference that it is hard to say what the worst-smelling essential oils are because everyone's list would be different.

5 essential oils really stood out as being unpleasant for several users. Here they are:

1. Patchouli Essential Oil

Patchouli essential oil was voted the worst-smelling essential oil. It has a deep, earthy aroma and is used extensively in perfumes, soaps, and cosmetics. Patchouli oil is also used in aromatherapy and has a range of benefits for health and well-being. It is believed to be helpful for anxiety, depression, and stress.

Patchouli essential oil is also thought to be helpful for acne, eczema, and other skin conditions. It can be used topically or inhaled but should be diluted before topical use on the skin.

"Patchouli, I know a lot of people that wear it as perfume/cologne (men and women) and they put on way too much, it is super overpowering and gives me a headache, almost makes me gag when I smell it on people." -Kristin F, CO

"Patchouli oil I do not care for because it reminds me of a hippy smell." -Karen R, CA

"Patchouli, I am a hippie from the 60s and it brings back not so good memories!!" -Deb W, TX

"Patchouli, I tried to like it. Mixed with orange the smell was OK. But to me it smells like cat pee." -Liz R, FL

2. Tea Tree Essential Oil

Tea tree essential oil is suitable for a lot of things. It can be diffused to help fight off colds and flu and clear up sinuses. You can also apply topically to soothe insect bites and stings, and even help heal cuts and scrapes.

Tea tree oil is also effective at assisting with fungal infections like athlete's foot, ringworm, and candida.

In addition, this oil has powerful antibacterial and antiviral properties, making it an excellent natural remedy for many common ailments and an excellent natural cleaning agent.

"Tea tree because it is soo strong" -Amy V, NY 

"I would have to say that the EO I dislike the smell of is also one of the most valuable and also one that I use most frequently and that is Tea Tree oil. I have used it successfully for so many things from topical for skin problems to use in my natural antibacterial multi-use cleaning products. I almost always use Tea Tree in conjunction with more pleasant smelling oils such as lavender and citrus which also have some of the same properties. " -Claudia S, CA

"Tea Tree oil. My brother spilled a bottle of it in my kitchen...took months to get the smell out. Am afraid to even order something that has it 'blended' in." -August S, MT

"Tea tree oil. Just don't like the smell." -Sherri F, CA

"Tea tree just because the smell is so overpowering to me." -Kristina C, TN 

3. Oregano Essential Oil

Oregano essential oil is gaining popularity for its wide range of benefits. It is a powerful antiseptic and can be used to cleanse cuts, scrapes, and other wounds. It can also be used to aid respiratory infections such as bronchitis and sinusitis.

Oregano oil effectively boosts the immune system, making it a valuable tool in the fight against colds and flu. It is also said to have anti-inflammatory and pain-relieving properties. Oregano essential oil is a versatile natural remedy in most home medicine cabinets.

"Oregano, don't like the stinky smell!" -Jen, CA Okay, so this is me, this oil got my #1 vote. I do not like the smell, and it is hard to get it out once I get it in my nose. I know there are fantastic oregano benefits, but it is hard to smell and use. I will add a drop or two into my blending blends.

"Oregano scent is too strong." -Mary Jo, NM

"Oregano! I love the herb in foods, but the fragrance of the oil is so potent that once I smell it, I can’t get it out of my sinuses, and it isn’t pleasant .:-(" -Cynthia M, SC

4. Lemongrass Essential Oil

Lemongrass essential oil has a wide range of uses and benefits. It is frequently used in aromatherapy and massage, which is believed to help reduce stress and promote relaxation. It is also commonly used in household cleaning products, as it is effective at combating bacteria and odors.

In addition, lemongrass essential oil can be used topically after diluting it with carrier oil to relieve muscle pain and headaches. It is also reputed to have insect-repellent properties, making it a popular choice for natural mosquito control.

"My least favorite essential oil is lemongrass, I try to avoid using it as much as possible because every time I get a whiff I start nonstop sneezing. These aren't good sneezes, these are the choking gagging sneezes. They can be quite painful too. I've given myself the benefit of the doubt and tried diffusing lemongrass in a blend using half the oil and I still suffer. It's safe to say that lemongrass is my least favorite oil. I look forward to learning from you about all the fun oils and how I can transition into have a whole stockpile of cleaning products." -Kim T, OR

5. Valerian Root Essential Oil

Valerian root has a strong odor due to the presence of volatile oils and compounds such as isovaleric acid. These components are responsible for the characteristic smell, often earthy or musty.

"Valerian, the smell is just horrendous!! Barbara S, TX"

More Least Favorite Essential Oils

I didn't anticipate some of my favorites on the worst-smelling essential oils list. I was shocked to read that some fans disliked orange essential oil (yes 2 people said orange), 3 people said peppermint, 1 said cypress...I LOVE each of these oils, and I use them every day. They also make a great essential oil combination too!

Some responders wouldn't name names, others were new oil users and haven't found one they disliked yet. Katharine M from NY said "All essential oils deserve love!"

"I don't have a least favorite. They all do their work and are all powerful healing remedies." -Tannath J.

Why Do My Essential Oils Smell Bad?

If you've noticed that your essential oils have started to smell bad, there are a few possible explanations. One possibility is that the oil has become oxidized. This can happen when the oil is exposed to too much heat, light, or air.

Another possibility is that the oil has gone bad due to bacteria growth. This can occur if the oil isn't stored correctly or gets contaminated.

Finally, it's also possible that you don't like how the oil smells. Each person's sense of smell is unique, so what may smell bad to one person may smell perfectly fine to another. 

If you're unsure why your essential oils smell bad, ask a professional for more advice.



How to Use bad Smelling Essential Oils

Many essential oils have potent aromas that can benefit our health. However, some essential oils have less pleasant smells that can be off-putting. If you find an essential oil that doesn't smell good, there are still ways to use it.

Thankfully, essential oils still work, even if you dislike the smell. Here are some things to try:

Use Fewer Drops of the Stinky Oil

• Try using fewer drops of the oil you dislike. Each drop of oil is so potent and concentrated. You can also dilute the oil in a carrier oil such as jojoba or coconut oil. This will help reduce the aroma's intensity while still allowing you to reap the benefits of the oil. 

Blend with Another Essential Oil

• Another option is to combine the essential oil with other oils that have more pleasant smells. This can help to create a blend that is both effective and pleasant-smelling.
• "I really do not dislike any essential oil. Each of them has a specific medicinal purpose. Some smell more "mediciny" or pungent. They can be diluted or blended with something else to be nicer to the nose. That's how perfumes are created ;) " -Sherry P.

Continue to Use Anyway

• "My least favorite oil is Juniper because of the smell. It helps me with lessening vertigo so I will continue to use it but I don’t like the smell of it." -Kris M, MI.
• "I really don't like the smell of Helichrysum, but I use it because it's a super oil." -Lisa W, GA

Learn to Like It Anyway

• "I find benefits in every single eo! Blend or single, every oil is beneficial to one person or another for various conditions. You may not accept the aroma at first but you and your body learn to accept and use them to their fullest potential" -Geralyn C.

Apply Smelly Essential Oils to Your Feet

• Instead of applying it close to your face and nose, try applying it to your feet or behind your ankles.
• The feet are ideal for applying essential oils because they are full of pores and quickly absorb them. In addition, the essential oils can then be diffused throughout the body, providing a range of benefits.

Find an Alternative Essential Oil

• There are so many essential oils available to purchase that you can easily find an alternative oil that offers similar benefits. I do not like Oregano, but thankfully, Sweet Marjoram is part of the same family and has similar benefits.

Just Be Happy

• "Other than not loving the smell of basil, I don't have any oils that I don't at least like. Whether I love the smell or the effect of a specific oil, they all make me happy!" -Bev J, AZ

Stop Using the Smelly Essential Oil

• Buy new essential oils in small bottles. That way, if you don't like it, you aren't out a lot of cash.
• "The smell of Spikenard is one I haven't gotten used to. It has great benefits but I haven't used it much because of the scent." -Kimberley Z, WA

Trial and Error

• Initially, you may not love the smell of an essential oil, especially if it just smelled out of the bottle. The aroma may change if applied to your skin or mixed with other oils in a blend.
• With some experimentation, you can find ways to use even the most potent essential oils without being overwhelmed by their smell.

When I first got patchouli oil, I didn't like it. I avoided it for about 2 years. Then I pulled it back out and tried it in different recipes and blends, and now I love the oil, primarily when it is used with orange essential oil. I even use it in an Essential Oil Solid Perfume Recipe!

Why Does My Essential Oil Diffuser Smell Bad?

If your essential oil diffuser is giving off a bad smell, there are a few possible reasons.

• First, make sure you are using high-quality essential oils. If the oils you are using are old or of poor quality, they will not evaporate properly and leave behind a residue that can cause a bad smell.
• It's also important to clean your diffuser regularly. If essential oils build up on the surface of the diffuser, they can start to degrade and produce offensive odors.
• Finally, ensure you use the correct ratio of essential oil to water. Adding too much essential oil can vaporize incompletely and leave an unpleasant smell in the air.

By following these simple tips, you can enjoy the benefits of essential oils without dealing with bad smells from your diffuser.

Why does patchouli oil smell so bad?

Patchouli oil is made by steam distilling the leaves of the Pogostemon cablin plant. While patchouli oil has many benefits, it is most commonly known for its strong, musky scent. 

This essential oil has a potent smell that can overwhelm some people. However, others find the scent to be grounding and relaxing.

If you do not like the smell of patchouli oil, you can try diluting it with a carrier oil such as jojoba oil or coconut oil. You can also try using less essential oil or diffusing it for a shorter time.
