Mold expert stumbles upon an amazingly powerful and non-toxic method of toxic mold removal…in his wife’s aromatherapy kit
In 2005, Edward Close, PhD, a mold remediation consultant with 30 years experience in the environmental industry, 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.
After much urging by his wife, he diffused Thieves oil 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 Thieves essential oil 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.
Disappearing Toxic Mold Spores
10,667 to 13 in 48 hours
75,000 to 0 in 72 hours
Most remarkable to mold remediation experts is that three factors about Thieves oil merge to create a 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. Thieves oil is approved as a supplement by the FDA. It’s so safe that workers can breath 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. Thieves 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. See more at his mold website.
While it is exciting to finally see Thieves-specific research on toxic mold, the following studies on the individual ingredients in Thieves have been telling us the same story for years.
Mold/Candida/Fungus Studies
| Fungus Type | Thieves ingredient | Abstract Summary |
| Rhizopus stolonifer | cinnamon | A wax paper infused with cinnamon essential oil completely inhibits the growth of Rhizopus stolonifer.View Abstract |
| Aspergillus flavusAspergillus fumigatusAspergillus nidulansAspergillus niger | cinnamon | 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 | Cinnamon oil caused inhibition of growth and aflatoxin production in Aspergillus parasiticus.View Abstract |
| Aspergillus flavusAspergillus nigerFusarium spp.Penicillium spp. | cinnamonclovelemon |
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. |
| Aspergillus flavusCandida albicansPenicillium islandicum | cinnamoncloverosemary | 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. | cinnamoncloverosemary | 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 | cinnamoncloveeucalyptuslemon

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.View Abstract |
| Coriolus versicolorLaetiporus sulphureus | cinnamon | Cinnamaldehyde, the major compound in cinnamon essential oil, showed strong antifungal indices against both Coriolus versicolor and Laetiporus sulphureus.View Abstract |
