MONQ, LLC is a wellness lifestyle company and we recommend our products for those interested in leading a holistic life.  However, everyone is different and you may have a different reaction to the ingredients of MONQ blends and adverse reactions can occur.  You are utilizing these products at your own risk.  You should not use MONQ diffusers if you are concerned about a potential adverse reaction, if you have any of the conditions listed below, or if advised not to use them by your healthcare provider.

The information provided to you on this website and on MONQ, LLC’s various social media sites as well as statements and products referred to throughout this site have not been evaluated nor approved by the FDA. MONQ® is not a medical product, and MONQ is not intended to diagnose, treat, cure or prevent any disease or condition, or otherwise affect the structure or function of the human body. If you have a health condition or concern, consult a physician or your alternative health care provider. Always consult a medical doctor before using any new product, including MONQ personal essential oil diffusers, and MONQ essential oils in bottles, roll-ons or bath soaks.

Be aware that some of the products on this site may interact with medications you may be taking, or medical conditions that you may be experiencing. These devices should not be used as a substitute for your own physician’s advice. You should consult your own physician regarding any issues related to your health. MONQ, LLC takes no liability for misuse of our Products, nor for your reliance on the information on our various websites. MONQ personal aromatherapy diffusers should be utilized according to our instructions. MONQ products should be purchased only from MONQ.com and authorized retailers to ensure the highest quality products. 

MONQ Diffusers are not intended for individuals under 18.


Allergic Reactions:

Allergies are rare with MONQ essential oil blends and yet we encourage you to read the list of the ingredients to ensure that you do not have a known sensitivity or allergy to any of them. If you are allergic to, intolerant of, or think you are allergic to or intolerant of any of the ingredients, you should not use MONQ products.  If you experience an allergic reaction, or any other adverse reaction to any of our products, we encourage you to seek medical care and to discontinue use. Please notify us as soon as practical, if you believe you have experienced an adverse reaction, of any nature, to any of our products. A variety of contact methods can be found on our Contact Us page. 

Not recommended for former smokers or asthmatics:

MONQ personal aromatherapy diffusers should be utilized according to the instructions.  We are cautious about recommending MONQ Diffusers to former smokers, as we don’t know if the use of a device of this nature will increase the urge to return to smoking, and therefore we do not recommend that former smokers utilize our personal aromatherapy devices. Keep these devices out of the reach of children and pets. The small plastic top to the shipping tube can be a choking risk to them.

Our discussion regarding the scientific basis behind aromatherapy is for your information only.  It includes some theories, including those surrounding Forest Bathing and terpenes that, while interesting, have not been proven factually, and should be interpreted as such. 


Essentially all substances, salt and water included, are dangerous, at inappropriate concentrations. The same can be said of the various aromatherapy constituents found within MONQ personal aromatherapy diffusers, as well as our bottled blends, roll-ons and bath soaks.  True allergies can occur with MONQ, and could lead to meaningful health-related issues. That being said, the overwhelming majority of issues listed below are dose-dependent, and are not likely to be problematic in the extremely low dosages found within MONQ diffusers.

Special Precautions Regarding MONQ Liquids in a Bottle

Please note that in June 2018 MONQ initiated a release of essential oil blends in a bottle that are not intended to be used in our Personal Aromatherapy Diffusers, nor in any form of personal and/or portable vaporizer.  These liquids are not to be placed into any e-cigarette, mod or other similar device produced by any manufacturer. 

Our suggested method of utilizing them remains via a personal method, such as via a pendant or necklace.  However, they are suitable for use within a standard desktop diffuser as well. MONQ does not sell eJuice, and in an abundance of caution we again remind you that MONQ Liquids which currently come in 10mL bottles are not to be used in a vaporizer.

Please be aware that, unlike our Personal Aromatherapy Diffusers, people can experience skin sensitivity including rashes and/or photosensitivity when using topical essential oils. These liquids are not to be taken internally, are not to be ingested, are not to be used topically, and should be kept out of the reach of children.

General Precautions

For thousands of years, cultures worldwide have utilized aromatherapy. The risks of an allergic reaction, or other adverse reactions, are present with all essential oils, including those used by MONQ. For a comprehensive review of essential oil safety, please consult the textbook by Robert Tisserand: Essential Oil Safety.

Interactions with Medications:

All essential oils should be properly diluted before use. Never ingest essential oils unless under the direction of a medical professional. In regards to pregnant/nursing women and small children, we advise not to use essential oils or products containing them on these populations. Some safety precautions for specific essential oils are based on ingestion or topical application, and also on exposure to extremely high volumes and/or concentrations. MONQ recommends that any individual with health concerns or taking prescription medications check with their medical practitioners and refer to appropriate medical research literature for possible pharmacological interactions and contraindications, prior to using any essential oils, including those sold by MONQ.

When using MONQ Diffusers with the LED light-activated, you are taking in vapor or mist, not burned products. Within the mist are a variety of naturally occurring plant extracts from organically grown herbs, spices and other plants from which aromatherapy products have been produced for centuries, in addition to the heated vegetable glycerin which makes up 80% of the contents.  

MONQ products are not to be inhaled into the lungs:

Just as with any new product we encourage you to use judgment and moderation. We do not recommend using MONQ excessively, and in fact, a few very gentle uses, a few times a day, is our recommended usage level. Furthermore, there is no need to inhale at all. In fact we strongly discourage inhalation into the lungs as it is unnecessary, and lowers the experience of MONQ.

Please note that while each of the main ingredients in MONQ devices has been shown to have certain independent effects when used alone, the final product containing all the ingredients has not been tested, and no specific claims are made for the combination of ingredients in any individual MONQ Diffuser. Furthermore, many of the specific plants and many of the specific terpenes which have been studied by independent researchers and subsequently referenced in the various articles on this website are not included in any of the current MONQ blends.  The references to the scientific literature are intended to provide background information on the subject of plant-based and terpene-based wellness benefits only, and no specific health claim regarding any MONQ blend should be inferred.

While many of the organic ingredients in our whole plant extracts have been used for thousands of years both in aromatherapy as well as in other forms of medicine, and their safety and health benefits with those uses have been well documented, breathing through a heated portable diffuser is very recent, and there are always risks with new methods of use. In addition, the effects of many compounds are altered when blended in various combinations, and the specific blends of MONQ essential oil blends have not been specifically tested. Please note, the International Federation of Aromatherapists does not recommend taking Essential Oils internally, such as swallowing them, but only inhaling them.

The main ingredient in MONQ personal aromatherapy diffusers is certified organic coconut-derived vegetable glycerin.  Vegetable Glycerin (VG) is vaporized by millions of people daily.  Whole-plant extracts have been utilized for thousands of years as aromatherapy constituents, and have been very well studied. The inhalation of heated essential oils has been done for centuries, such as by adding them to boiling water over a fire.  However, they have not been heated and utilized using an electronic device until approximately 20 years ago, and thus there is no long-term experience with essential oils used in this manner.

It is believed that extended breathing of concentrated essential oils can be deleterious to your health. Please note that MONQ personal aromatherapy diffusers do not contain concentrated essential oils, but rather diluted essential oils, and inhalation is not the proper method of use. If you are concerned about this, don’t use MONQ personal aromatherapy diffusers.

People with known upper respiratory illnesses or weaknesses, such as asthma or COPD, should not use MONQ personal aromatherapy diffusers.

Side Effects of MONQ Therapeutic Air Diffusers

We would appreciate being notified of any adverse event that occurs to you so we can document them here.  Note that the most frequent side effects are a dry mouth, loose stools, and mild irritation of the throat or eyes.

Dry mouth is usually a result of inhaling the mist of the vegetable glycerin base.  This is a common occurrence when vegetable glycerin is heated. Many users find that this feeling of a dry mouth recedes on its own after a relatively short period of time, frequently measuring days or a couple of weeks.  For others, they find that drinking more water can be very effective. If this is disturbing to you, you should discontinue the use of any MONQ diffuser. Note that we offer a 30-day unconditional money-back guarantee, and if you are dissatisfied, for any reason, please contact us for a refund.

Some upper respiratory irritation may be due to allergies.  If you develop any upper respiratory irritation, you should discontinue using MONQ products immediately.  Please note that as the liquid in the device is used up, the blend may begin to taste bitter or, even stale.  This is an indication that the useful life of the product is over and that you should discontinue using that specific diffuser. MONQ original diffusers devices are not refillable, but you can recycle them or check out our eco-friendly option, MONQ R, a rechargeable portable aromatherapy diffuser that allows you to switch out different Blend PODs (personal oil diffusers) while using the same rechargeable device, eliminating additional waste.

Vegetable Glycerin has frequently been used as a suppository to prevent constipation.  You may find that you have a looser stool than usual when first starting with MONQ products or you may find a bit of nausea or an upset stomach.  In most instances this, like dry mouth, is transitory. While MONQ has not been notified that our products have caused all of these potential effects, other reported adverse effects from vegetable glycerin are aches, wheezing, swelling of the tongue and gastroenteritis.  Again, should you experience any of these issues, you should discontinue using MONQ products immediately, and seek medical attention should the severity of your condition warrant it.
