Natural Remedies for Mold & Mildew Allergies
Mold and mildew allergies occur when the immune system erroneously responds to mold spores, causing symptoms that include itchy eyes, sneezing and fatigue. Allergy medications, such as antihistamines and decongestants, can help relieve mold allergy symptoms, but may cause unwanted side effects that include dry mouth and sedation. While there is no known cure for mold and mildew allergies, natural remedies may help alleviate symptoms while reducing the overall stress on your immune system.
If you are experiencing serious medical symptoms, seek emergency treatment immediately.
Foods that are fermented or contain mold may worsen symptoms in a small portion of sensitive individuals. According to the Asthma and Allergy Foundation of America, fermented foods, such as:
- red wine
- can trigger the release of histamine by constricting blood vessels
- resulting in increased allergy symptoms (http://www.aafa.org/display.cfm?id=9&sub=16&cont=58 ‘inline-reference::Asthma
- Allergy Foundation of America: Mold Allergy’)
Actual allergic reactions to fungi in foods are rare and aren’t necessarily more likely to occur in people with mold and mildew allergy. Foods high in sugar may promote overgrowth of Candida yeast in the body, which can interfere with digestion and immune function.
Herbs And Supplements
Herbs with anti-fungal properties can help ease symptoms of mold and mildew allergies. Garlic is one of the most well known anti-fungal herbs available. According to the National Institutes of Health, garlic contains the compound ajeone, which inhibits the growth of Candida and Aspergillus fungi 2. Other herbs with anti-fungal effects include pau d’arco, oregano oil and tea tree oil. Nutritional supplements, including vitamin C and selenium, may also help lessen allergy symptoms by strengthening the immune system.
Over-the-counter supplements can cause dangerous side effects and interactions with other herbs and medications. To prevent negative reactions, ask your doctor before taking an herbal or nutritional supplement.
Prevention is the best treatment for mold and mildew allergies. Decreasing exposure to mold spores in your home environment is an important factor in treating allergic reactions.
To control humidity levels, use a dehumidifier in damp rooms, including bathrooms and basements. Keep vents and fans clean, and consider buying an air cleaner with a HEPA filter to help remove mold spores from the air. Keep gutters clear of debris and address leaks within 48 hours to prevent extensive water damage and mold growth.
Keep an eye on the local allergen forecast, and avoid outdoor activities when mold spore counts are highest. Wear a mask when raking leaves or doing yard work, and keep windows closed in your home and car to prevent additional mold spore exposure.

Is Hidden Mold at Home Making You Sick?
March 23, 2004 — Except for an occasional asthma flare up, Caitlin Murray is a healthy, happy 5-year-old, who loves doing artwork. But three years ago, she was terribly sick, and no one could figure out why.
«She would have terrible headaches and her face was swollen and she’d throw up sometimes for seven to 10 days,» Jill Murray, her mother said. «They tested her for cystic fibrosis, for leukemia, all kinds of diseases and they couldn’t find anything wrong with her.
Caitlin said it was a terrible feeling.
«I was like really, really sick,» she said. «I was feeling like I was going to die in a few days.»
Her mother had a gut feeling that whatever was making her daughter sick was in their Pennington, N.J., home.
«We started working with the head of the diagnostic center at Children’s Hospital Philadelphia,» Jill Murray said. «He said ‘Try it. Leave your house. That’s the only way you’ll know.’ «
In the basement, Murray checked inside a crawlspace. There was mold everywhere.
«And with that we just got out,» Murray said. «We literally took the shirts on our backs and left.»
Caitlin’s suffering went on for three years before the girl finally felt better. The Murrays’ experience is not unique. Because modern homes are more tightly sealed for energy efficiency, water — which mold needs to survive — gets trapped inside.
Modern building materials like wood, drywall, wallpaper and fabric are appealing food sources for mold, while building technologies such as synthetic stucco can leak and trap moisture inside. Home appliances including clothes dryers and dishwashers also generate water vapor, again creating the type of environment that mold can thrive on.
Concerns About Toxic Mold
«Mold spores are everywhere,» said Meg Hamilton, CEO of Hamilton Thorne Biosciences. «They’re in your house, in your attic, on the street, in your living room, in your kitchen. It’s a question really of how much and what species.» Some molds are worse than others, said Tom Kelly, a director of the indoor environments division at the federal Environmental Protection Agency.
«There are a relatively small number of mold species that have been identified as producing a kind of toxin called mycotoxin,» Kelly said. «What’s not clear is whether they are toxic to human beings.»
Some industry experts say there’s growing evidence that they may be.
«We certainly are beginning to see strong indications that the so-called toxic mold can make you very ill,» Hamilton said.
Whether some molds are more dangerous than others is just one of the questions researchers like Dr. David Zhang, a research biologist at New York’s Mt. Sinai Medical Center, are trying to answer. There are more than 100,000 mold species, and about 50 are considered toxic. He has invented a DNA-based technology that spotlights the bad ones.
Scientists and doctors do agree on one thing: about one in three people can have allergic reactions to mold. For asthma sufferers who are very young, like Caitlin, or elderly, mold can trigger much more serious problems.
Destroying Home Values
The fungus can affect more than just health. Dan Sitomer, an attorney specializing in mold litigation, says it could destroy the value of your home.
«For the moment in time that that building is viewed as a problem its value goes to zero,» Sitomer said. «The litigation is so aggressive and has multiplied so quickly that it has frightened the insurance industry. The damages can include almost anything. Pain and suffering, negligence, the claims go on and on.»
Most insurance policies do not cover damages related to mold, according to Gordon Stewart, president of the Insurance Information Institute. «In 44 states, mold is excluded, unless it is the direct result of a peril that is covered,» Stewart said. For example, some insurance companies do not cover mold, but do cover water leakage, which can cause mold to grow.
Meanwhile, articles about mold — like one in the magazine Redbook headlined «It’s Invisible. It’s Deadly. And It’s in your home» — have made many homeowners nervous. With unanswered health questions, the looming risk of litigation, prospects of nose-diving property values and no insurance safety net, what’s a homeowner to do?
Experts agree on one thing: If you’ve got mold you need to get rid of it. More importantly, you need eliminate the cause.
«We say: ‘Find the moisture, eliminate the moisture, clean up the mold,’ » Kelly said. «Come back a month later, make sure it’s still gone.»
It is possible to have mold and not know it. If you can’t find it yourself, a «mold dog» may be able to help. Jason Earl, a mold inspector works with a mold dog named Oreo. In the same way dogs can be trained to detect drugs and explosives, Oreo can find mold, he says.
Tracking Mold in Your Home
How does mold get into houses?
Mold is everywhere, in the air indoors and out. To reproduce, mold generates spores (seeds) that become airborne. These spores can remain dormant for 50 years or more.
They become active when they come into contact with moisture and food. Where there’s mold there is always water. Mold colonies develop which, in turn, release more spores into the air. How do you know if you might have mold?
Surface mold. Signs of water intrusion (discoloration, peeling or bubbling paint, bulging walls or ceilings). Water intrusion (broken pipe, flooded basement, roof leak, etc.) that wasn’t completely dried out within 24 — 48 hours. A musty smell.
Persistent physical symptoms (sneezing, runny noses, red eyes and skin rashes) that seem to lessen when the sufferer is not at home. If you see mold on the walls or floors of your home, and it’s less than a 3-foot by 3-foot patch, clean it using bleach and water, and let it dry completely. If you see any spots larger than that, contact an industrial hygienist. (Try the American Industrial Hygiene Association at aiha.org for a referral.)
When should you consider a mold inspection?
When there is a musty smell, but you cannot find any visual evidence. When there is visual evidence and you need to determine the extent of infestation and damage. When there is no visual evidence or smell, but a member of the family has persistent symptoms (sensitivities vary by individual). When you need help locating the source of the water that’s causing the mold. When you’re buying or selling a home. When you need a formal plan to remove the mold and repair the damage.
When you need someone to supervise mold removal and repairs.
How do you select someone to remove the mold and fix the damage?
It is recommended that inspection and remediation not be done by the same person/firm. Insist that the firm/person have a contractor’s license. Look for remediators who are certified. Check with the licensing board and Better Business Bureau for complaints. Ask for references for similar jobs. Call references and ask if the job was done properly, on time and within budget. Inquire if a mold test was done after the remediation work. If you see mold, find the source of moisture, correct it and clean up the mold. If you see signs of water leaks, investigate for mold.
If you smell mold, consider having a qualified mold inspection firm test for mold, locate the mold, determine the extent of the mold, determine the source of moisture and come up with a remediation plan.
How do you prevent mold?
Locate and fix water leaks immediately. Dry water from water leaks within 48 hours. Make sure clothes dryers are properly vented to the outside. Use exhaust fans when cooking, showering or using dishwasher. Insulate exterior walls to prevent condensation inside. Keep indoor humidity below 50 percent. Remember: Just cleaning up mold is not enough. You must find the water source and eliminate it.
How do you clean up mold?
Wear rubber gloves and eye protection. For larger infestations (more than several square feet) wear a N-95 respirator. Wash hard surfaces with water and detergent. Discard absorbent materials like carpet and ceiling tiles. Cleaning up the mold is not enough. You must eliminate the water source.

- separately check the humidity in the kitchen and bathroom, troubleshoot the plumbing;
- install electric dehydrator system;
- if there are places where the paint went to the hills, remove it, treat the surface with an antiseptic to remove the mold, and paint over with a fresh layer;

Here are a few recipes that you can use on different types of surfaces without harm to get rid of mold.
4 tbsp.l.borax, half a cup of white vinegar and 4 cups of warm water, mix to a uniform consistency and spray the spray with a solution of the surface of the apartment. After 10 minutes, carefully wipe dry thoroughly and repeat the procedure for removing the fungus with the antiseptic again.

Further, the whole surface is cleaned with sandpaper, including the previously cleaned areas, and the treatment with furatsilin solution begins. This must be done repeatedly, 5-6 times. And only after this, antiseptic and plaster are used.
