Glami, a firm specializing in natural herbal tea for hangover relief -> -> ->

Dear teachers,

I have 2 questions seen below:

1. It was evaluated by the Korean Food Research Institute as improving liver function and having gastric mucosal protection properties.

=> Does this sentence could be understood as follows?

It was evaluated by the Korean Food Research Institute as improving liver function properties.

It was evaluated by the Korean Food Research Institute as having gastric mucosal protection properties.

2. As Dawn 808 was also the world’s first internationally patented hangover drink, it was able to sweep all of the ten major international invention fairs.

=> Could you please let me know the meaning of "sweep"?

In the dictionary, I found "sweep" only implying physical movement.

Thanks and best regards,

David Kim
