Intestinal Cleansing Support

Pure Oregano has powerful anti-yeast, anti-bacterial, and anti-viral properties, as well as intestinal cleansing benefits. It is often used with intestinal Candida/yeast, and as a first aid to help treat food poisoning. Oregano oil has also been found to have powerful antioxidant effects.

Pure Oregano has powerful antioxidant and intestinal cleansing benefits.  It also helps to maintain a healthy microbial balance. The formula contains a 10:1 extract, which is the equivalent of 1,500 mg of oregano. 

Pure Oregano is a powerful plant extract with highly effective antimicrobial properties, as well as important antioxidant and intestinal cleansing benefits. Similar to rosemary, garlic, ginger, turmeric, and other common herbs and spices, oregano is a familiar culinary ingredient whose potential pharmacologic role can be exploited when its essential components are isolated and provided in concentrated doses.

The oil extracts of Mediterranean oregano (Origanum vulgare) and other varieties have a history in botanical medicine for efficacy in the gastrointestinal tract as antimicrobial, antifungal, and antiparasitic agents.


The principal phenolic compounds in oregano—carvacrol [2-methyl-5-(1-methylethyl)phenol] and thymol (2-isopropyl-5- methylphenol)—are well known for their individual antibacterial properties, and when provided together as oregano oil, they have an additive effect.1,2 They have both been shown to be biocidal against strains of Staphylococcus, Listeria, Salmonella, and Clostridium.3 A study of two strains of Staphylococcus microorganisms in vitro showed oil of oregano to be highly effective in attenuating the growth of the Staph biofilm. The researchers proposed that the hydrophobic properties of carvacrol and thymol enabled them to interact with the lipid bilayer of bacterial cell membranes, “causing loss of integrity and leakage of cellular material such as ions, ATP and nucleic acids.”1 In the presence of these compounds, bacterial cells grew as looser colonies and the amount of biofilm was reduced in direct proportion to the dose of oregano extracts.


Oil of oregano has been shown to be a powerful antiparasitic. A small study involving 13 patients with three different intestinal parasites and complaints of GI distress and fatigue resulted in the complete eradication of parasites in 10 patients, along with amelioration of bloating, cramping, fatigue, and alternating diarrhea and constipation after 6 weeks of supplementation with 600 mg oil of oregano (200 mg t.i.d.). This powerful result was obtained with no other dietary or lifestyle modifications.11 A study investigating the antiparasitic properties of Mexican oregano showed it to be more effective against multiple strains of Giardia than the common antiparasitic drug, tinidazole. The mechanisms of action were similar to those observed in antibacterial studies: disruption of cell membranes leading to changes in osmotic balance, as well as irreversible damage to the anchor proteins of the nucleus.12

Why emulsify with olive oil?

Concentrated essential oils can be irritating to gastrointestinal mucosa. To avoid this, the oil of oregano in our product is emulsified in olive oil as a carrier. Additionally, emulsification increases the surface area of the essential oil particles, with one study estimating that 200 mg of oil could theoretically cover the entire luminal surface of the small intestine.11
