Organic Oregano Leaf Extract

Also known as: Oregano, Wild Marjoram, Greek Oregano, Italian Oregano, Origanum vulgare

Overview

Oregano (Origanum vulgare) is a perennial herb native to Europe, North Africa, and Western Asia, widely recognized for its culinary and medicinal applications. The herb is rich in bioactive compounds, particularly carvacrol, thymol, and rosmarinic acid, which contribute to its antioxidant, antimicrobial, and anti-inflammatory properties. Its use extends beyond flavoring food; oregano is being investigated for potential anticancer activity and serves as a natural preservative due to its ability to inhibit microbial growth and lipid oxidation. While existing animal studies and preclinical research demonstrate these myriad benefits, the need for more human trials is crucial to substantiate any health claims associated with oregano intake.

Benefits

Oregano is primarily noted for its antimicrobial effects, with studies showing inhibition of pathogens like *Brochothrix thermosphacta*. Its strong antioxidant capabilities are evidenced by favorable IC50 values, signaling its role in combating reactive oxygen species (ROS) and possibly aiding in conditions such as colon cancer due to its anti-inflammatory properties. Additionally, oregano supports gastrointestinal health and exhibits food preservation efficiency. However, it must be noted that, though animal studies indicate potential human benefits, the limited nature of human trials suggests caution in extrapolating these findings broadly.

How it works

The primary active compounds in oregano, carvacrol and thymol, exert antimicrobial effects by disrupting microbial cell membranes, thus causing cell death. Its antioxidant activity is facilitated by phenolic compounds that scavenge free radicals, reducing oxidative stress. Oregano also modulates immune responses and inflammatory processes, contributing favorably to overall health. Extraction methods can significantly impact the bioavailability and absorption of these active compounds, influencing their efficacy.

Side effects

Oregano is generally safe for consumption, particularly in culinary amounts. However, excessive intake or prolonged use may lead to gastrointestinal issues and allergic reactions, though severe reactions are rare. Individuals on blood-thinning or diabetes medications should be cautious due to potential interactions. Pregnant or breastfeeding women are advised to avoid high doses due to a lack of safety data. Additionally, those with allergies to Lamiaceae family plants should be careful when using oregano to avoid adverse reactions.

Dosage

Dosage recommendations for oregano can differ based on the intended therapeutic benefit. For antimicrobial effects, research suggests effective dosages range from 100-200 mg/kg of oregano essential oil in animal studies. For antioxidant and anti-inflammatory benefits, daily doses between 500-1000 mg have been utilized in trials. While no official maximum safe dosage exists, intakes over 2000 mg per day are discouraged. Consistent daily supplementation may offer benefits for chronic conditions, and preparation methods can affect absorption, with methanolic extracts often providing superior bioavailability.
