ABSTRACT
Introduction: This paper reports the results of a post marketing clinical study that tested the antiviral properties of
Gene-Eden-VIRTM. Specifically, the clinical study tested the effect of Gene-Eden-VIR on the severity, duration, and
frequency of symptoms reported by individuals infected with various viruses. The viruses included the Human Papillo-
mavirus (HPV), Herpes Simplex Virus (HSV), Epstein Barr Virus (EBV), Human Cytomegalovirus (HCMV) and
Hepatitis C Virus (HCV). The symptoms included abnormal Pap smear, low and high grade cervical dysplasia, warts,
blisters, cold sores, hives, skin tabs, panic attacks, depression, kidney problems, sleeping problems, liver problems, fe-
ver, fatigue, sore throat, swollen lymph nodes, diarrhea, and weight loss.
Treatment: A capsule of Gene-Eden-VIR in-
cludes five natural ingredients: 100 mg of quercetin, 150 mg of green tea extract, 50 mg of a cinnamon extract, 25 mg
of a licorice extract, and 100 mcg of selenium. The dosage was 1, 2, 3, or 4 capsules per day. The duration of treatment
was 2 to 54 weeks.
Population: The study population consisted of 60 infected individuals, ages 20 to 66.
Results: The
participants reported no side effects after taking Gene-Eden-VIR. Seventy three percent of the individuals treated with
Gene-Eden-VIR reported a decrease in their symptoms. Specifically, they reported a decrease in the severity (p = 0.006,
n = 45), duration (p = 0.009, n = 34), and frequency of their symptoms (p < 0.001, n = 31). Following treatment, the
participants also reported an increase in their physical abilities (p < 0.001, n = 47), energy levels (p < 0.001, n = 54),
mental abilities (p < 0.001, n = 44), and general health (p < 0.001, n = 46). The results showed that Gene-Eden-VIR has
a duration effect (p = 0.044, n = 32), that is, those treated for a longer time reported a larger decrease in their symptoms.
The results showed no interviewer bias, no selection bias, and a surprising response shift. The results also showed that
Gene-Eden-VIR has therapeutic consistency under varying manufacturing conditions.
Conclusions: This post market-
ing clinical study showed that Gene-Eden-VIR is a safe and effective antiviral treatment. Specifically, the clinical study
showed that Gene-Eden-VIR is a safe and effective treatment against the Human Papillomavirus (HPV), Herpes Sim-
plex Virus (HSV), Epstein Barr Virus (EBV), Human Cytomegalovirus (HCMV), and Hepatitis C Virus (HCV). There-
fore, health care practitioners should recommend Gene-Eden-VIR as a safe and effective antiviral treatment against
these viruses.
