Extractum cepae is Latin for onion extract, specifically from the bulb of the red onion (Allium cepa). It is an ingredient in some topical scar treatments, like Contractubex gel, where it works with heparin and allantoin to reduce inflammation, prevent excessive scar tissue formation, and improve scar appearance, stiffness, and color.
Properties and Uses
Anti-scarring properties: Extractum cepae helps to prevent the formation of hypertrophic scars (raised, excessive scars) by suppressing chemical activity involved in inflammation and scarring.
Anti-inflammatory and bactericidal effects: It has properties that reduce inflammation and kill bacteria.
Improves scar appearance: Studies show it can significantly improve scar color, stiffness, and irregularity.
Wound healing: It is used in topical gels for the prevention and treatment of scars, particularly those from surgery or injury.
How it Works
The extract contains various bioactive compounds, including flavonoids, quercetin, and sulfur compounds.
It is thought to work by suppressing prostaglandin F1-beta (PGF-1b), a chemical that promotes inflammation and excessive scarring.
In summary
Extractum cepae is a beneficial component in scar management due to its anti-inflammatory and anti-scarring actions, which promote more normal and less problematic scar healing.
