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.

Samsung Research Reveals Over Half of Europeans Admit to Looking at a Stranger's Phone Screen in Public – With Nearly a Quarter Doing so out of Sheer Curiosity1.4.2026 09:00:00 EEST | Press release

As millions of Europeans2 get ready to enjoy the Easter weekend, new research from Samsung finds Europe’s public spaces have become shared screens: 56% of people say they have accidentally looked at a stranger’s phone, citing public transport as the most likely place to notice someone else’s screen (57%). Nearly one in four Europeans2 (24%) admit to looking at someone else’s phone out of curiosity, exposing a stream of private content from personal photos to bank details. Samsung Electronics surveyed 11,000 Europeans2 to support the launch of the Galaxy S26 Ultra, which introduces a built-in Privacy Display. This new hardware-based technology keeps screen content visible only from the front to protect privacy from side angles, without compromising the viewing experience3. The study further reveals a gap between perceived phone privacy and reality: While 48%* feel their own phone use is private when using it in crowded places, 52%** find it easy to view someone else’s screen in public.
