For me, a Vietnamese, when I gets flu, I always eat a hot bowl of rice porridge with GINGER, green onion, coriander and some shredded chicken. That helps my body sweating and I feel more energy. This photo is the chicken porridge my partner cooked for me last time when I had a cold flu!
I know that lots of people use ginger when they are sick maybe I must also try it. Here they use it more in teas
Ginger is the best natural immune system booster. So if you want to try a bit first, just cut 2 thin slices of it and crush, put into some soup! It will be perfect but ginger not goes well with some seafood!
