It also reduces the severity of Flu and Cold symptoms if they are already present, and works to accelerate recovery – naturally.

Flu-X® was developed by Professor D.S. Liu, Ph.D, one of China’s most eminent and respect virologists and medical doctors, during China’s SARS epidemic in 2002/2003. Due to its highly safe and effective anti-viral properties and its success in preventing and treating SARS-CoV infected patients and and preventing SARS-CoV infections at several hospitals in China, the original drug was rebranded as Flu-X®. Over the past 5 years, this product has been sold in Canada, the US, the UK, and China.

Additional Information

Scientific Evidence

A 160 patient placebo-controlled clinical trial of patients with Viral Respiratory Tract Infection demonstrated an 82.9% recovery rate in the Flu-X group compared to 19.6% in the placebo control group. Further, comparative in-vivo studies on mice confirm the product’s superiority to Interferon, a leading anti-viral pharmaceutical against the influenza virus, offering a protection rate of 55% compared to only 40% for Interferon. In clinical tests Flu-X has also been shown to inhibit the H.Influenza, Aureua Staphylococcus and A-hemolytic Steptococcus bacteria strains, associated with secondary flu-related, respiratory bacterial infections.

Long and short term clinical toxicology studies conducted on the product confirm Flu-X to be safe even at 400 times the recommended human dosage. Additionally, the product has been used by over 1,000 volunteers and has been shown to be safe and highly effective in the prevention and treatment of influenza, by killing and preventing the replication of the Influenza A & B Viruses.

The similarities between SARS-CoV and SARS-CoV-2 are striking, not only in name. The whole genome of SARS-CoV-2 has a 86% similarity with SARS-CoV. Both viruses share high degrees of homology to SARS-like viruses isolated in bats, suggesting that bats are the probable origin of both SARS-CoV and SARS-CoV-2. Even in terms of disease   dynamics there are apparent similarities.   The main transmission route is thought to be respiratory droplets, although viral shedding via faeces has also been reported for both   viruses.  The angiotensin-converting enzyme 2 (ACE2), found in the lower respiratory trace of humans, has been identified as the receptor used for cell entry for both SARS-CoV and SARS-CoV-2. To be clear, Flu-X is not proven to address

Didn’t think it would work

I started feeling the soreness in the back of my throat right when the whole world started shutting down due to the Coronavirus. With two kids at home and my wife, I was terrified that I had contracted it. Thankfully it wasn’t Covid, but I was still worried it was the flu friend suggested this product. I used as suggested, and still had symptoms before bed and in the morning, but during the day I was in top shape. A bit of fogginess and heady numbness but nothing that affected me much. I never really subdued to the symptoms of the flu, just a sneeze here and a cough there and I was perfectly fine 3 days later! I usually don’t trust “natural” products as I think most of them are snake-oil. But this works. 5-sprays, 4 times a day. Simple.
