A recent clinical study has shown that the ViroStop anti-viral spray from Swiss company, Herb-Pharma is effective in reducing the impact of Covid-19 for patients with mild to moderate symptoms.

The key benefits were a 60% reduction in viral shedding after using the treatment and a reduction in the severity of clinical respiratory symptoms. The study supports the findings of earlier in-vitro tests where its mix of polyphenols inhibited the growth of the virus in cell cultures.

The study included 170 PCR confirmed SARS-CoV-2 patients at the Complex Medical Clinic in Budapest, Hungary between January 15th, and May 31st, 2021. The volunteers all had mild to moderate respiratory symptoms, having tested positive in PCR tests for Covid-19 at the start of the study, and their symptoms were monitored over 12 days.

Of the 170 volunteers, 86 received a nasopharyngeal spray, the patented ViroStop solution, which contains a mixture of Cistus Creticus and other polyphenol-rich ingredients. Polyphenols when attached to viral protein, mechanically inhibit the workings of the protein, and thus stop the virus from entering the cell. The rest of the 84 patients remained in the control group and were not given the ViroStop solution. Each patient’s symptoms were checked every two days for 12 days.

At the end of the study the level of viral shedding was checked by PCR tests. Those patients who had used the ViroStop spray from the first day after testing positive, showed an almost 60% reduction in viral shedding on day 12, compared to the control group. The study showed that the severity of respiratory clinical symptoms was also reduced in those who used ViroStop spray.

A reduction was also noted in gastrointestinal symptoms compared to the control group. Recent research has shown that a key factor in the spread of the virus is its ability to also multiply in the gastrointestinal tract.

Dr István Jankovics, whose team ran the study commented, “The primary treatment for Covid 19 is, of course, vaccination, however this study means that the use of the ViroStop spray significantly inhibits the amount of SARS CoV-2 in the upper respiratory tract, thus providing an opportunity for the infected person to develop a specific immune response.”

ViroStop is a non-prescription treatment, made from natural ingredients and can be taken safely by children as young as three. Furthermore, at the time of the study, at least three variants of the virus were present in Hungary, so it is reasonable to assume that the solution and the action of polyphenols is effective against all known mutations of Covid-19.

Artificial intelligence has emerged as the most critical challenge facing CEOs worldwide, ahead of geopolitical instability and economic uncertainty, according to The CEO Response, Egon Zehnder's third annual study of 843 global chief executives. Nearly half of CEOs (48%) consider the adoption and impact of AI an extremely critical challenge, up from 37% in 2025. Geopolitical instability (44%) and economic uncertainty (40%) follow, while 62% expect geopolitical disruption to increase over the next 12 months. These challenges are shaping where CEOs are focusing their efforts. Half (50%) identify AI investment among the three most important changes they're making to their organizations, followed by innovation (48%) and improving their cost base (41%). By comparison, 29% selected upskilling and talent development as a top priority. “CEOs can invest in AI much faster than they can change how an organization works,” said Francesco Buquicchio, Global CEO of Egon Zehnder. “That gap matters.

Grafana Labs Brings Faster Full-text Search and Smarter Data Optimization to Grafana Cloud at ObservabilityCON 202620.10.2026 20:00:00 EEST | Press release

Grafana Labs, the company behind the open agentic observability cloud, today announced new releases at ObservabilityCON 2026 that help teams manage their telemetry in the AI era, finding the right log line in seconds and keeping only the telemetry worth paying for as AI workloads scale. Major query performance enhancements to Grafana Cloud Logs, built on technology from the company's Logline acquisition, are now generally available, and Adaptive Logs Archive is in public preview. AI is massively increasing telemetry volumes. Coding agents are turning everyone into a developer, so more software is being built, faster, and all of it needs to be watched. The agents add to the load too, since every agent call and tool call emits its own telemetry. Left alone, observability costs grow with every new workload, which makes cost and query optimization non-negotiable for running AI at scale. In the 2026 State of Observability Report, also released this week by Grafana Labs and ETR, a Futurum co
