A Natural Solution for Removing Toxic Mold

| | Articles

Not only are mold and mildew unsightly, but they can also be seriously detrimental to your health. Mold and mildew spores are known causes of allergies, sinus infections, and skin irritation, to name a few. Essential oils have been proven to be a natural solution to this serious problem.

The potency of pure essential oils reveals a non-toxic and natural method of fighting mold. Mold growth and exposure may be inhibited with these natural plant compounds. There are numerous studies showing the effectiveness of certain essential oils assisting in mold and fungus issues, as well as supporting immune function to aid in recovery from toxic mold exposure.

Mold RX Expert

Edward Close, Ph.D., a mold remediation consultant with 30 years experience in the environmental industry, with awards from many South Beach and Pompano Beach mold removal companies, was asked to do third-party sampling for mold in an apartment complex that had been flooded, evacuated, and later put up for sale. The buyer who was renovating the apartments had paid a company which had used the strongest stuff they knew of—a hospital disinfectant. Yet Dr. Close’s sampling showed that either the product had not killed the mold or that the mold had already re-established itself.

Dr. Close diffused Young Livings' Thieves blend (a branded proprietary blend of five essential oils) in the Aroma-Ace Essential Oil Atomizing Diffuser in the apartments for a 24-hour period. The research project yielded astonishing results, and two weeks later they were even more astonishing!

In another instance, 10,667 stachybotrys mold spores were identified in a per cubic meter area. After diffusing the Thieves blend for 48 hours, Dr. Close retested. Only thirteen stachybotrys remained. Similarly, 75,000 stachybotrys mold spores were identified in a sample of sheetrock. After 72 hours of diffusing, no stachybotrys mold spores remained.

The Perfect Storm Against Toxic Mold

  • It’s powerful. But so is diesel fuel.
  • It’s safe. Many things (like diesel) may kill mold, but they are toxins themselves. So you exchange toxins and the building is still uninhabitable. The oils in the Thieves blend has an FDA supplement facts panel on the label. It’s so safe that workers can breathe it while it’s diffusing.
  • It’s long-lasting. While mold may be reduced immediately by standard remediation products, it often makes a fast comeback. The Thieves blend continues killing the mold for weeks afterward.

Dr. Close documented his first 20 case studies (yielding similar results) in his book Nature’s Mold Rx, the Non-Toxic Solution to Toxic Mold.

Abstract Summary

Rhizopus stolonifer


A wax paper infused with cinnamon essential oil completely inhibits the growth of Rhizopus stolonifer. View Abstract

Aspergillus flavus

Aspergillus fumigatus

Aspergillus nidulans

Aspergillus niger

Candida albicans

Candida tropicalis

Candida kefyr

Histoplasma capsulatum


Vapors of cinnamon bark oil prove to be a potent fungitoxicant against fungi which cause respiratory tract mycoses: Aspergillus niger, Aspergillus fumigatus, Aspergillus nidulans, Aspergillus flavus, Candida albicans, Candida tropicalis, Candida pseudotropicalis (Candida kefyr), and Histoplasma capsulatum. View Abstract

Aspergillus parasiticus


Cinnamon oil caused inhibition of growth and aflatoxin production in Aspergillus parasiticus. View Abstract

Aspergillus flavus

Aspergillus niger

Fusarium spp.

Penicillium spp.

Rhizopus spp.




Citrus limon (lemon) essential oil and the phytochemical eugenol (found in cinnamon and clove) were among compounds used to test the sensitivity of mold strains Fusarium spp., Rhizopus spp., Aspergillus flavus, Aspergillus niger, and Penicillium spp. Eugenol showed prominent anti-mold activity. View Abstract

Aspergillus flavus

Candida albicans

Penicillium islandicum




Essential oils of cinnamon and clove showed strong inhibition of mold when tested for the possibility of creating a protective atmosphere by using natural compounds that could extend the shelf life of packaged foodstuffs. The oils were tested against Candida albicans, Penicillium islandicum, and Aspergillus flavus. Rosemary was included in the test but results weren’t as strong. View Abstract

Aspergillus spp.

Eurotium spp.

Penicillium spp.




Cinnamon, rosemary, clove essential oils exhibited antifungal activity against Eurotium spp., Aspergillus spp. and Penicillium spp., the most important molds in terms of spoilage of bakery products. These findings strengthen the possibility of using plant essential oils as an alternative to chemicals to preserve bakery products. View Abstract

Botrytis cinerea






Among 20 oils tested, cinnamon and clove essential oil demonstrated the antifungal activity against Botrytis cinerea. Essential oils D-limonene, cineole, Beta-myrcene; Alpha-pinene, Beta-pinene, and camphor showed high antifungal activity. Lemon and rosemary and eucalyptus contain these compounds.

Coriolus Versicolor

Laetiporus sulphureus


Cinnamaldehyde, the major compound in cinnamon essential oil, showed strong antifungal indices against both Coriolus Versicolor and Laetiporus sulphureus.

Dr. Close's Mold Rx Protocol

Dr. Edward Close and his wife, Jacquelyn A Close discovered that diffusing essential oils with a COLD AIR DIFFUSER was the best solution to address mold in buildings. To date, thousands of people have told us that their life has been saved or made better by the information we have made available. Essential oils are the best option for addressing mold in buildings and the body. Using all natural, 100% organic, safe and effective therapeutic grade essential oils is the only non- toxic solution currently available.

Using the Aroma-Ace Essential Oil Diffuser for Eliminating Mold in Buildings

The Aroma-Ace™ Essential Oil Diffuser comes with a five-year warranty and is manufactured in the USA. Change essential oils in seconds with the innovative quick-change system. Simply twist a new bottle of essential oil into the atomizer at any time without mixing or spilling. Advanced, built-in, easy-to-use timers provide exceptional operational control and convenience. State-of-the-art Cold Diffusion technology preserves the natural essence and complete therapeutic benefits of essential oils by effectively transforming them into a micro-fine vapor without the use of heat or water. These microparticles permeate the air and remain suspended for hours, fully intact, with all of their NATURAL defenses against airborne viruses, bacteria, mold, pests, and odors. Other common uses are for respiratory therapy, mood enhancement, relaxation, wellbeing, air purification and more.

Aroma-Ace Operating Instructions for Mold Remediation Recommended by Dr. Close:

1. Use the bottle that comes with the Aroma-Ace Diffuser.

2. Be certain the plastic ring around the neck of a bottle is removed before attaching to the diffuser.

3. For maximum results, place one diffuser in each room and diffuse continuously for a minimum of 24 hours. How long you have to diffuse (24-48 hours or longer) can only be determined by appropriate air and tape-lift sampling.

4. To prevent mold (maintenance), diffuse for 8 hours continuously once a week; or diffuse for 20 minutes 2-3 days per week; or diffuse once a month continuously for 24 hours. This is also a good way to do maintenance after doing a 24-48 hour remediation protocol.

5. Use one diffuser for every 1,000 sq ft of floor space when ceilings are no higher than 10 ft.

6. Put a glass plate under the diffuser to protect furniture finishes from spills.

7. Setting the three controls on the Aroma-Ace diffuser:

  • Top Control – RUN Time should be set all the way to the RIGHT for maximum time on.
  • Middle Control - REST should be set all the way to the LEFT for minimum time off.
  • Bottom Control – OUTPUT should be set all the way to the RIGHT for maximum output of the oil.

When you use the Aroma-Ace, with the settings given immediately above, the diffuser will be off (REST) for a short period (less than 1 minute) at the end of every 20-minute cycle (RUN).

The Aroma-Ace diffuser utilizes a cold diffusion technology to atomize essential oils. As a result, the Aroma-Ace Diffuser starts diffusing at a high rate of delivery but that rate decreases over time as the oil level in the bottle drops. This necessitates refilling the bottle on the diffuser every 10-12 hours in order to maintain a sufficient dispersion of oil. The diffuser will not be harmed if it runs dry as it is a cold air jet pump with no heat.

UPDATE: Diffuser World now provides an optional 30 ML Bottle / Atomizer Attachment (double the size) for the Aroma-Ace to reduce the time between refills.
