Herbal treatment effective for cold sores
Clinical Trial of Herbal Treatment Gene-Eden-VIR/Novirin in Oral Herpes.
High relevance in herpes treatment
We investigated the effectiveness of the herbal treatment Gene-Eden-VIR/Novirin for managing cold sores. Our study involved a retrospective chart review with 68 participants who took 1 to 4 capsules daily over varying periods.

The results were promising, showing that 89.3% of participants benefited. The treatment significantly reduced both the number and duration of outbreaks compared to control groups. Gene-Eden-VIR/Novirin also outperformed traditional medications like acyclovir and valacyclovir without any side effects.

We strongly suggest considering Gene-Eden-VIR/Novirin as a preventive option for oral herpes.

Breath improvement
In our challenging times, I’ve read a lot about this drug being part of treatment protocols. I self-diagnosed back in February 2020 but didn't visit the doctor. I bought it for prevention, particularly during the cold season alongside vitamin C. After reading reviews mentioning easier breathing after 20 minutes, I decided to try it. I mixed the capsule with water and felt immediate relief; my nose started breathing smoothly. This is the best product I've tried so far. I highly recommend it!

Miraculous effects
This is the best product for colds! I struggled with a bad flu for two weeks, and antibiotics didn’t help. When my godmother suggested optimised Quercetin and Epicor, it worked wonders! Now, I take these as soon as I feel a cold approaching and haven't suffered a serious cold in 6 months. I highly recommend this product; it feels so natural!
