A current international in vitro study demonstrates the / multi-target effect of benzyl mustard oil against MRSA

Eschborn – According to a recent meta-analysis published in The Lancet, antibiotic-resistant bacteria were responsible for at least 1.2 million deaths worldwide in 2019.[1]. To avoid the problem of resistance, experts have been calling for antibiotics for uncomplicated infections, such as urinary tract and respiratory infections, for many years, but prefer proven antibacterial herbal substances such as mustard oils (isothiocyanates) from licorice and horseradish (in ANGOCIN® Anti-infective N) as first-line therapy[2]. A new international in vitro study now provides further evidence that the benzyl mustard oil contained in licorice even has a significant antibacterial effect against problem germs, such as e.g. MRSA (Methicillin-resistant Staphylococcus aureus) caps[3]. Previously In-vitroStudied at the University of Friborg[4] as well as several international research papers[5-7] confirm a wide range of antibacterial effects of mustard oils even against dangerous bacteria, such as MRSA, Klebsiella, vancomycin-resistant enterococci (VRE) or durable Escherichia coli (E. coli)-Tribes. “The use of herbal medicine in acute, uncomplicated urinary and respiratory tract infections can significantly contribute to stopping the deadly threat of resistant pathogens,” says microbiologist and hygienist prof. Uwe Frank from Freiburg, who is responsible for basic research into mustard oils.

Antibiotic resistance is one of the leading causes of death worldwide and thus one of the greatest threats to human health, as explained by the authors of an analysis published in the Lancet.[1]. According to this, in 2019, there were more than 100,000 deaths worldwide due to infections MRSA attributed. MRSA are among the pathogens that most often cause problems with resistance. The embryo is a common and dangerous cause of nosocomial infections. A recent study from the USA shows this MRSA-Transporters: have significantly increased mortality[8]. For example, those who carried the bacteria on their skin – usually unknowingly – had a double risk of dying within the next 10 years. MRSA-Non carriers. Study participants who wore staphylococcus on their skin did not MRSAno increased risk of premature death was identified.

Extensive study situation – a wide range of antibacterial activity

Mustard and horseradish mustard oils have been used for centuries in traditional medicine to treat urinary and respiratory tract infections. Numerous studies prove a wide range of antibacterial effects of plant substances[4-7]. In the current study of the University of Shaanxi / China[3] benzyl mustard oil from licorice was able to inhibit growth MRSA-They contain pathogens. An earlier study by Portuguese scientists even found that benzyl mustard oil has a significant bactericidal effect MRSA established[7].

In-vitroStudies from the University of Freiburg confirm that the combination of mustard and horseradish mustard oils has a significant inhibitory effect on all 13 pathogens of respiratory and urinary tract infections analyzed in the study and relevant in practice.[4]. Next to MRSA there were, among other things, streptococci, VRE and ESBL-forming E-coli and Klebsiella pneumoniae analyzed. Research by researchers from Freiburg has also shown that the combination of the two plants and the mustard oils they contain (mixing ratio as in ANGOCIN® Anti-infective N) complement each other in their effect and a particularly wide range of antibacterial effects can be achieved. In addition, herbal substances inhibit uropathogens E-coli (UPEC) as well as their adhesion and motility and prevent the formation of bacterial biofilms – a bacterial mechanism that is often associated with recurrent urinary tract infections[9-12]. Due to the multimodal effects of mustard oils, the development of possible mechanisms of resistance in bacteria is significantly more difficult[13-15]. “Given the dramatic development of resistance and the search for new antimicrobials that do not cause resistance, the anti-infective potential of mustard oils is therefore of great value,” concludes Frank. Numerous other research projects also confirm that the herbal medicine has a strong anti-inflammatory effect, which significantly contributes to the improvement of the symptoms of acute respiratory and urinary tract infections.[16-18].

Licorice root and horseradish recommended in two directives

Based on comprehensive scientific data on the effectiveness of mustard oils from licorice and horseradish was their use

2017 recommended in guideline S3 “uncomplicated urinary tract infections” for recurrent cystitis[19]. The good study situation and the tolerability of the mustard oil mixture have also been taken into account since 2021 by the updated S2k guideline “Urinary tract infections in childhood”. The directive recommends: Mustard and horseradish mustard oils can be used as a supportive measure for uncomplicated recurrent cystitis in late childhood and adolescence[20].
