Multiple Chemical Sensitivity Symptoms can seem overwhelming but can be avoided if you know what to look for.

There is nothing worse than having to sit next to someone wearing perfume. It’s not because I don’t like the smell, it’s because it actually makes me sick.

Being exposed to fumes, candles, fragrances, plug-ins, air fresheners or new products that give off gasses can put me in bed for days with a horrible migraine headache.

How can a smell affect your health? Breathing in perfume can cause the release of histamine in some people giving them an allergic reaction.

It’s not just perfume, it can be paint fumes, dryer sheets, scented candles or anything with artificial fragrance.

Do you have any of these chemical sensitivity symptoms?

Multiple Chemical Sensitivity Symptoms

  • A headache
  • A runny nose
  • A migraine
  • Joint Pain
  • Watery Eyes
  • Sinus Problems
  • Rapid heartbeat
  • Air hunger
  • Rash
  • Hives
  • A sore throat
  • Dizziness
  • Brain fog
  • Confusion

Did you happen to notice that all these symptoms are the same as histamine intolerance symptoms?

When you are exposed to a chemical, it produces histamine as an allergic response to the chemicals. It can be chemicals in your food, pollution in the air, cleaners in your home or just in your environment.

It’s extremely frustrating to live with reactions to smells and chemicals. I find myself blowing out candles when no one is looking, shopping only for fragrance-free items and checking ingredients constantly.

Multiple Chemical Sensitivity and Histamine Intolerance

Bear with me for a second but Multiple Chemical Sensitivity and Histamine Intolerance sound like the same thing. I haven’t met a person dealing with histamine issues that aren’t sensitive to smells and chemicals.

I don’t think these are two separate illnesses, I think it all comes under someone dealing with histamine issues or mast cell issues.

So why do people react to smells and why do their histamine levels rise when exposed to chemicals?

For most people, it’s an over triggered immune system caused by food allergies or gut infections.

When you start reacting to everything around you…the histamine levels in your body are overflowing so to speak.

If you have a gut infection which a lot of people with histamine issues do… the bad gut bacteria or candida overgrowth cause tons of extra histamine in the gut. 

Infections also inhibit the production of DAO which is an enzyme that eats away extra histamine.

If you are eating something you are allergic too, that is a great way to skyrocket your histamine levels daily. You must eliminate the foods that are triggering your histamine.

For me personally, after taking care of my gut infection and cutting out foods my body didn’t like, I can tolerate smells for a longer period of time before it cause some problems.

Now I don’t dare wear perfume just for the sake of it or light stinky candles in my home but overall my reactions to chemicals have calmed down greatly and are very manageable.

How to get rid of a gut infection

Gut infections can take hold by eating too much sugar, stress, overuse of prescription medication and alcohol use.

Bad gut bacteria overgrowth or SIBO (small intestine bacterial overgrowth) or candida infections can be reduced by cutting out sugar and adding in some supplements to kill the candida or bad gut bacteria.

By focusing on your gut health, you can reduce the level of histamine floating around in your body thereby reducing reactions to chemicals.

Oil of Oregano

This is a powerful oil that does a great job of killing off candida and bad gut bacteria, almost like a bomb in your intestines. Oregano oil is anti-viral, antibacterial and anti-fungal. In this study, it was shown to kill off parasites in the gut and improve overall gut health.

It’s also been shown to lower inflammation and decrease pro-inflammatory cytokines in colitis patients in this study.

We love Gaia Herbs Oregano Oil for killing off bad gut bacteria and candida. This oil is strong and shouldn’t be taken long term.

Olive Leaf Extract

This powerful herb is antifungal, antiviral and antibacterial but is a little more gentle on the gut and digestive system. Olive leaf extract has been shown to reduce candida and slow virus growth and lower blood pressure.

Many people including myself have found Olive Leaf Extract to be helpful in reducing gut infections and decreasing histamine reactions.

ProBiota HistaminX

I have been taking this probiotic and have noticed a huge difference in my chemical sensitivity reactions since taking it. The bacteria strains in this probiotic have been chosen because the bacteria actually eat away at extra histamine in the gut.

ProBiota HistaminX is a smart choice for anyone dealing with Chemical Sensitivity and histamine intolerance issues because it works to lower histamine levels and reduce allergic reactions.

Smart Products for Multiple Chemical Sensitivity

It can seem impossible to find chemical-free brands and products that don’t cause reactions. I have found some resources I would love to share with you that you can safely use in your own home.

Home Cleaners

If you have Multiple Chemical Sensitivity you know how frustrating it can be when you have to use a cleaner or degreaser in your home. Nothing is worse than spraying a product and reacting a few minutes later.

Puracy is a brand of products that are hypoallergenic, vegan, gluten-free, and chemical free. These plant-based cleaners are safe for your kids, pets, and anyone with allergies.

Eden’s Garden

This isn’t just an essential oil company that I adore, Eden’s Garden has expanded into making plant-based products free of harsh chemicals and toxins. Recently they introduced all-natural deodorant, room sprays, and soy-based candles.

Normally I would never ever light a candle in my home but these candles use soy and coconut based wax with nontoxic wicks and are gently scented with real essential oils. This is a candle I can use and won’t aggravate my chemical sensitivity symptoms.

Check out Eden’s Garden for a line of home products that will not aggravate your histamine issues and chemical sensitivity.


Finding laundry detergent that cleans well and is fragrance-free can be a huge problem for many dealing with chemical sensitivity symptoms. Luckily, Charlie’s Soap has developed a completely fragrance-free detergent that cleans amazingly.

Please never use those stinky dryer sheets from the grocery, I get chemical sensitivity symptoms just walking down the aisle. You can choose a chemical free option like Budieggs Wool Dryer Balls to get the wrinkles out of your clothes and shorten drying time.
