What are the therapeutic properties this herb?

The main therapeutic properties of Origanum vulgare are attributed to its ability to inhibit the growth of pathogenic microorganisms, exerting its antimicrobial properties through the presence of carvacrol, a volatile oil responsible for its bactericidal and fungicidal activities.

Origanum vulgare also exhibits significant antioxidant properties, scavenging free radicals and protecting cells from oxidative damage due to the presence of flavonoids such as ursolic acid and oleanolic acid. The plant's anti-inflammatory properties are mediated by the sesquiterpene carnosol, which inhibits the production of pro-inflammatory enzymes and cytokines, contributing to its analgesic and anti-edematous effects. Additionally, Origanum vulgare has been found to possess antiviral properties, hindering the replication of various viruses by disrupting the viral envelope and interfering with viral replication machinery.

Furthermore, its antifungal activity is attributed to the presence of saponins, which disrupt the fungal cell membrane and inhibit the growth of fungal pathogens.

What are the medicinal constituents this herb?

The most important healing constituents of Origanum vulgare are carvacrol, thymol, linalool, bornyl acetate and caryophyllene oxide.

Carvacrol exhibits antimicrobial, anti-inflammatory, and antioxidant properties due to its ability to inhibit the activity of enzymes involved in the production of inflammatory mediators and its scavenging activity against free radicals. Thymol has been shown to have antimicrobial, antiseptic, and antifungal properties, which contribute to its use as a natural preservative and disinfectant. Linalool, a monoterpenoid alcohol, has been found to possess anti-inflammatory, antioxidant, and antimicrobial activities, while bornyl acetate, a sesquiterpene, demonstrates antimicrobial and anti-inflammatory properties.

Caryophyllene oxide, a sesquiterpenoid, has been identified as an inhibitor of inflammatory mediators and a potent antioxidant, contributing to its therapeutic potential in the treatment of various inflammatory conditions.

What are the main herbal preparations this herb?
