Why Sophora Japonica Extract Can Help Prevent COVID-19
- Oct 28, 2021 -

Clinical medicine has already confirmed in 2005 that hydroxychloroquine is a blocking drug, which can block the replication of coronavirus in human cells and tissues. In 2020, when the COVID-19 broke out in Wuhan, China, clinical medicine proved that hydroxychloroquine can block the replication of the new coronavirus in the human body, but the cost performance is not as good as quercetin extracted from sophora japonica extract.


●The principle of quercetin antiviral

The cost-effective quercetin is a natural plant that can act as a zinc ionophore. It has the same mechanism of action as hydroxychloroquine and can help zinc pass through the cell wall, thereby slowing or preventing virus replication.

●The experimental theory of quercetin antiviral

Epidemiological investigations and clinical medical experiments after the outbreak of the COVID-19 have proved that the average daily intake of quercetin in Spain is 18.48 mg, which is much higher than the 9.75 mg of Americans because Spain likes to drink tea, juice, beer, and wine, and also like to eat citrus fruits, cantaloupe, apples, onions, strawberries, and bananas. The result is that Spain's epidemic control status is better than that of the United States.
