A natural alternative to antibiotics


The carvacrol molecules in Ropadiar® come into contact with the bacterial cell wall so that the mechanism of action based on the unique properties of carvacrol can unfold


The carvacrol molecule increases the permeability for protons and ions in the cell membrane of the bacterium, so that it looses its integrity


Vital cell components such as nucleic acids and ATP are leaking away. Metabolic processes that are crucial for the energy supply of the bacteria are disrupted, and the bacterium dies

The mode of action

An important part of the activity of Ropadiar® can be ascribed to carvacrol. Our essential oil consists of at least 70% of this organic compound. Numerous scientific studies have shown that carvacrol has a strong activity against a broad spectrum of micro-organisms. Against bacteria, including: Staphylococcus aureus, Escherichia coli, Pasteurella multocida, Streptococcus faecalis, Streptococcus agalactiae, Vibrio coli, Enterobacter aerogenes, Streptococcus uberis, Proteus rettgeri, Salmonella spp, Proteus vulgaris, Proteus mirabilis, Klebsiella pneumoniae, Corynebacterium pyogenes, Pseudomonas. aeruginosa, Cryptosporidiae spp., Streptococcus pyogenes anim.C, Erysipelothrix insidiosa, Mycobacterium tuberculosis and Treponema hyodisaenteriae. Against fungi, including: Aspergillus spp, Mucor spp, and Candida spp. Against parasites, among others: Eimeria spp, and Histomonas meleagridis.

Thymol also contributes to the activity of Ropadiar®. Thymol is found to be very effective against certain micro-organisms . Since both carvacrol and thymol are found in oregano it is believed that oregano has a stronger effect, and possibly kills a broader spectrum of micro-organisms than carvacrol alone.

Wild oregano contains four times as many antioxidants as blueberries. These polyphenols mitigate oxidative stress, protect against free radicals, thereby preventing damage at the cellular level.

In animal studies carvacrol and thymol showed to have a blood vessel relaxing effect on the aorta tissue, laboratory tests also show a beneficial effect of oregano oil on glucose and lipid metabolism and a preventive effect of carvacrol on DNA damage in rats.

In Oregano, dozens of other components are identified, whose properties are yet to be explored. The function of many of these substances is still unknown.

So there are many components in oregano that contribute to its activity, but ultimately the success of Ropadiar® is largely due to the synergy between these components. This means, the ingredients help, complement and strengthen each other. This is where the efficacy of our product is based on.

Resistant bacteria

The danger, what is antibiotic resistance?

Resistance to an antibiotic means that a particular type of bacteria becomes insensitive to an antibiotic. The antibiotic is no longer able to kill the bacteria or to inhibit its growth.

One of the greatest risks of the use of antibiotics in livestock breeding is that it may lead to an increase in the number of resistant bacterial strains.

Animals can transmit resistant bacteria to humans. For example agricultural animals, but also pets like dogs and cats. Besides, People can also transfer resistant bacteria to animals. Moreover, resistant bacteria can be transmitted to humans via the environment (soil, water, air, manure, (swimming) water), and food that is contaminated with resistant bacteria can also infect humans.

In addition, residual antibiotics may remain in meat and animal by-products. Eventually people may consume these materials, with a potential impact on our health.

Partly due to the use of antibiotics as growth promoters in animal feed, physicians increasingly have to divert to other antibiotics that are considered «the last option to cure» because common antibiotics no longer work. Antibiotic use thus poses a real threat to public health.

The solution Ropadiar® as an alternative!

Since the efficacy of Ropadiar® against microorganisms relies for 100% on natural oregano, bacterial resistance is not an issue. Not any scientific study has ever found an indication that bacteria are capable to adapt, or to resist oregano. It is assumed that this can be explained by the fact that the oregano plants consist of hundreds of different complex elements, in contrast to synthetic drugs, like antibiotics.
