Good news for weebs: Natto is very medicinal.
The enzyme Nattokinase found in Natto can kill pathogens in the digestive system, reduces inflammation, breaks up blood clots, and likely reverses many types of cancer. It is also effective against viruses like Covid-19, and can even dissolve the spike proteins from people who have been vaccine injured. Also it helps you lose weight fast.
