Let us start by explaining what soy sauce is.
Soy sauce is made from fermented soybeans, water, salt and sometimes roasted grains. It has a dark brown color and is usually salty.
Soy sauce is usually eaten with sushi, dipped in slightly and preferably by adding some wasabi and ginger.
Although soy sauce has its origins, which is mostly associated with the Asian and Japanese cuisine, it can always be used for different purposes.
One odd reason soy sauce can be used for is burns. Yes burns…
Of course if the burn is severe then immediate medical attention is required.
When experiencing a mild burn on an area apply cold water then directly put some soy sauce on the burn. This can help ease the pain and redness from a burn (again, if it is severe seek medical attention).
The sodium content in the soy sauce may be a good explanation but if the soy sauce is low in sodium then it may not be very effective.
Again, these are used for mild burns only.
Just a small tip that we could give.
