Extractum Cepae is a botanical active ingredient frequently used in dermatological treatments to improve the healing process of skin. It works by inhibiting the growth of excessive scar tissue and reducing inflammation. This extract is a core component in many trusted generic gels and creams used for treating various types of scars. Our platform offers access to effective, verified pharmaceutical products containing Extractum Cepae for skin recovery.
Extractum Cepae is the botanical name for onion extract, a plant-derived substance that belongs to the group of flavonoid-rich extracts. It is most commonly used for its potential to support normal skin healing and to improve the appearance of raised scars. In the United Kingdom, you will find this ingredient in products such as Contractubex.
The best-known medication that contains Extractum Cepae is Contractubex, a topical gel that also includes heparin and allantoin. Contractubex is available in 1 % (w/w) onion-extract concentration and is supplied in 5 g and 15 g tubes. It is a licensed product in the UK and can be purchased over the counter in pharmacies and some online stores. While a generic version of onion-extract gel exists, most UK customers encounter the brand name Contractubex. The formulation is a clear, slightly viscous gel intended for application to flat or raised scar tissue.
These uses are based on the ingredient’s ability to modulate the skin’s repair processes, which can lead to scar tissue that is less prominent. The product is intended for external use only and is not a cure for any medical condition.
Onion extract contains compounds that may help regulate the balance of collagen during skin repair. By supporting normal collagen formation, the ingredient can reduce excess tissue buildup, which often results in raised scars. Users often notice a gradual softening of scar tissue over weeks of consistent application. The effect is not instantaneous; rather, it works alongside the body’s natural healing timeline.
Most people experience only mild and temporary reactions, such as a slight stinging sensation, mild redness, or a brief warm feeling at the application site. These effects usually resolve without the need for medical attention.
Although uncommon, some individuals may develop an allergic response. Signs of a serious reaction include swelling that spreads beyond the scar area, intense itching, hives, or difficulty breathing. If any of these symptoms appear, stop using the product and seek urgent medical help.
Extractum Cepae is a topical ingredient, so it does not interact with oral medicines in the same way systemic drugs do. However, avoid applying the gel on open wounds that are still bleeding, and keep it away from the eyes. Alcohol-based hand sanitiser or strong detergents may reduce the gel’s effectiveness if applied immediately before or after use. For a full list of possible interactions, refer to the specific medication’s information page.
Store Contractubex in a cool, dry place away from direct sunlight, and keep the cap tightly closed to maintain gel consistency. The product is generally intended for short-term use on fresh scars, but some users continue application for several months to maintain results. Always follow the instructions that come with the specific medication, as formulation strength and recommended duration can differ.
