Organic Oregano Extract
Also known as: oregano, wild marjoram, *Origanum vulgare*
Overview
Oregano (*Origanum vulgare*) is a perennial herb originating from the Mediterranean region, recognized for its multifaceted culinary and medicinal applications. This herb is celebrated for its bioactive compounds, notably carvacrol, thymol, and rosmarinic acid, contributing to its antioxidant, antimicrobial, and anti-inflammatory properties. The use of oregano as a dietary supplement has gained traction, particularly in the realm of traditional medicine. While numerous studies explore its potential benefits, the research maturity level is moderate to high, with a mix of quality evidence, predominantly from in vitro and animal studies, indicating significant health-related applications, albeit with a need for more extensive human clinical trials to solidify claims.
Benefits
Oregano presents several evidence-backed benefits. Its antimicrobial properties are significant, inhibiting various bacteria like *Listeria monocytogenes* and *Staphylococcus aureus*, particularly through its essential oil, which has shown efficacy in multiple studies. In terms of antioxidants, oregano extracts demonstrate strong free radical scavenging abilities, essential for combating oxidative stress. Secondary effects include anti-inflammatory and anticancer potentials highlighted by animal studies, while its application in oral health, notably through mouthwash formulations, has proven effective in reducing halitosis over a short duration compared to traditional agents like chlorhexidine. The quality of evidence varies from high-quality trials to limited studies focusing on animal models.
How it works
Oregano works primarily through its bioactive compounds. Carvacrol and thymol exhibit potent antimicrobial action by disrupting bacterial cell membranes and hindering metabolic processes within bacteria. Meanwhile, antioxidants like rosmarinic acid neutralize free radicals, mitigating oxidative damage. These actions also influence the digestive and immune systems; for instance, oregano has shown effects on nutrient digestibility and may modulate immune responses through its anti-inflammatory capacities.
Side effects
Oregano is generally considered safe at moderate doses. The most common side effects (occurring in over 5% of users) include gastrointestinal disturbances such as nausea and diarrhea, particularly at higher doses. Less frequently, allergic reactions and skin irritations may occur. Severe allergic reactions are rare, affecting less than 1% of users. Notably, oregano may interact with blood-thinning medications and diabetes drugs due to its antioxidant and anti-inflammatory effects. Pregnant and breastfeeding women are advised to avoid oregano due to limited safety data. Individuals with allergies to plants in the Lamiaceae family should employ caution.
Dosage
Recommended dosages vary by form and intended use. For essential oil applications, a typical usage is around 0.05% w/w for antimicrobial effects. Oregano extracts are generally taken at doses between 100-500 mg per day, contingent on the extraction method. Although no maximum safe dose is established, doses exceeding 1 gram daily may elevate the risk of adverse effects. It is advisable to consume oregano with meals to alleviate potential gastrointestinal upset. Essential oils should be diluted for topical use or in mouthwash formulations, while extracts can be taken orally. Bioavailability may vary based on extraction methods used.
