antimicrobial essential oils

3. Menagerie There are over 1,000 species of parasites that can live in your body. Doctors can only identify and test for 5% of these parasites. Several parasites have emerged as significant causes of food borne and waterborne diseases. 30% of parasites live in our digestive system; 70% live throughout the body including the blood, brain, eyes and sinus.

4. Asymptomatic Not all parasites produce acute illness—many cause subtler chronic symptoms Flu-like symptoms Allergies Weight loss Ravenous appetite Abdominal bloating, gas, cramping, diarrhea, nausea Fever Joint pain Disturbed sleep Muscle cramps Sugar cravings

5. Costs In the US annually: $3.5 billion spent on OTC cough remedies $2 million spent on “natural” medicines that fight colds $1.3 billion spent on direct medical costs to fight flus 70 million work-loss days associated with illness Lost productivity in the workplace costs businesses $15 billion

6. National Institutes of Health: About 90,000 deaths annually from infections that don’t respond to treatment More and more bacteria (such as Staph. aureus and numerous gut bacteria) are resistant to the most powerful antibiotics available Centers for Disease Control: Doctors prescribe antibiotics to children 65% of the time if they feel parents expect them, even if not needed Nearly all significant bacterial infections in the world are resistant to the most commonly prescribed antibiotics Tiny Creatures, BIG Problem

7. Essential Oils: antimicrobial champions! Thyme (>55% thymol) Clove (>80% eugenol) Oregano (>60% carvacrol) Our Solution

8. Safety Eugenol (from clove EO), thymol (from thyme EO), and carvacrol (from oregano EO) have been used in dentistry since the 19th century for root canals, temporary fillings and cements, periodontal therapy, and abscesses Bernard Schechter, DDS Currently designated GRAS by the FDA Clove oil mixed with zinc oxide powder to form a filling paste for teeth still currently used.Clove oil mixed with zinc oxide powder to form a filling paste for teeth still currently used.

9. Thyme

11. Thyme vs. Microbes A 1995 study by Nicole Didry at the College of Pharmaceutical and Biological Sciences in Lille, France Thyme oil at very small concentrations (<500 ppm) killed the pathogenic organisms responsible for the tooth decay, gingivitis, and bad breath Streptococcus mutans, S. sanguis S. milleri S. mitis Peptostreptococcus anaerobius Prevotella buccae P. oris P. intermedia

12. Essential Oil vs. Oral Pathogens

13. Researchers at the Scottish Agricultural College Daily doses of thyme oil (42.5 mg/K of body weight), drastically slowed age-related DHA degradation in the brain Karesh Youdim and colleagues 3.9 mg thyme and clove oils for 17 months slowed DHA loss Jukic et al (2007) Thyme oil and derivatives slow destruction of neurotransmitters Thyme for Health

15. Thyme: The Bottom Line Research shows us that thyme essential oil: Is potently antimicrobial Has been used for centuries in oral health (and health in general!) May slow or reverse aging of brain tissue by protecting DHA, antioxidants and neurotransmitters May slow or prevent age-related eye tissue damage by protecting DHA

16. Clove

17. Clove: Long History Subjects awaiting an audience with Chinese emperors were required to chew cloves to mask breath odors (207 B.C. to 220 A.D.) Avicenna treated “putrifaction” of the teeth and gums with clove pills (~1000 A.D.) New England physician, Thomas Palmer, wrote in 1696: “Oyl of cloves—stayeth ye putrifaction of the bones in old and new ulcers . . . It heals wounds, diseases, wind, digesteth cold humours. Causes a sweet breath.” Thomas Berdmore, Operator for the Teeth to King George III, treated toothache with “acrid aromatic substances” including mace and cloves (late 1700s)

18. Clove: Long History The Island of Ternate in the Moluccas Archipelago was the site of extensive clove cultivation in the 16th century Dutch destroyed the clove trees to protect their monopoly Native inhabitants were devastated by disease (60,000+ thought to have died) Researchers attributed the sudden onset of epidemics to the lack of “clove leaves and flowers sufficient to purify the air.” Some East Indies natives still wear clove stuck to nostrils and lips so demons do not enter there

19. Safety Safety confirmed by NTP in lifetime animal studies (1983, Technical Report No. 223, National Toxicology Program) Ames salmonella assay also showed eugenol to be antimutagenic (1995, Azizan & Blevins, East Tennessee State University) Animals studies at the University of Wisconsin Medical School achieved similar results in an animal model. The Joint FAO/WHO Expert Committee on Food Additives estimated an acceptable human daily intake of eugenol of up to 2.5mg / kg body weight The German Commission E monograph prescribes mouthwashes consisting of 1 to 5% clove essential oil as an oral antiseptic and topical anesthetic, stating that it has “antibacterial, antifungal, antiviral” action

20. Clove vs. Microbes

21. Clove vs. Microbes Eugenol strongly inhibits growth of HSV I and HSV II Eugenol significantly delayed the onset of herpetic lesion on the eyes of infected animals

22. Clove vs. Microbes Bacteria and fungi tend cluster together in clusters called biofilms that serve as a powerful protective mechanism Biofilms make the microorganisms much more difficult to kill Clove is one of the few natural compounds that can disrupt these biofilms Recent studies have shown that eugenol disrupts Candida biofilms. [1] Ahmad et al., “Antimicrobial activity of clove oil and its potential in the treatment of vaginal candidiasis,” 2005 [2] He et al., “In vitro activity of eugenol against Candida albicans biofilms.” 2007.

23. Clove for Health According to a test developed by USDA researchers at Tufts University clove bud oil is the most powerful antioxidant known

24. Clove for Health Nagababu et al (1995) showed that eugenol protected against CCl4 hepatotoxicity (liver damage) Due to eugenol’s amazing free radical scavenging activity! Also showed that eugenol protected against lipid damage from free radicals (1994)

25. Clove: The Bottom Line Research shows us that clove essential oil: Is potently antimicrobial Is an incredibly powerful antioxidant Is an amazing anti-inflammatory Has been used for centuries in oral health (and health in general!) Shown to protect DHA in retinal tissue

26. Oregano

27. Oregano vs. Microbes

28. Oregano vs. Microbes A 2001 Georgetown University Study found that oregano oil at a concentration of 0.25 mg/ml completely inhibited candida growth Entire control group died in 10 days (100% mortality) Mice infected with Candida fed 8.6 mg of oregano oil for 30 days had only 20% mortality

29. Oregano vs. Microbes Adam et al (1998) Oregano essential oil at a 1/50,000 dilution caused 95% kill of human pathogenic fungi In vitro and in vivo No mutagenic activity! Daouk et al (1995) Oregano oil at 0.1µl / mL strongly inhibited common (and deadly) food fungi

30. Research at Weber State University by Sue Chao found that 12 microliters of oregano had the antibacterial equivalence of 10 units of penicillin. Oregano vs. Microbes

31. Streptococcus pneumoniae before Oregano Oil exposure

32. Streptococcus pneumoniae after Oregano Oil exposure

33. Harry Preuss, MD, at Georgetown found that oregano oil (in particular, carvacrol) works as well as antibiotics on Staphylococcus aureus. Oregano oil also killed E. coli, Heliobacter pylori, Bacillus anthracis, and Klebsiella pneumoniae Penicillin resistant Phase 2: animal studies 50% of mice fed oregano oil for 30 days survived Staph. aureus infections Control mice died within 3 days Oregano vs. Microbes

34. Oregano for Health Carvacrol and thymol in oregano oil are antioxidants Slamenova et al (2007) Very small concentrations of carvacrol protected cells against DNA damage from hydrogen peroxide Carvacrol and thymol themselves did not damage DNA

35. Oregano: The Bottom Line Research shows us that oregano essential oil: Is potently antimicrobial Many microbes that are resistant to common antibiotics Is a powerful antioxidant that helps protect DNA from damage Is not mutagenic or cytotoxic to cells

36. So What? Infectious disease and growing antibiotic resistance are major threats to our health Essential oils, especially thyme, oregano and clove, can help! Powerful antimicrobials No resistance demonstrated Synergistic: also support health in other ways Internal and external benefits Centuries of safe and successful use
