|Luo han guo and ginger tea|
So I have been making him Luo Han Guo (罗汉果) Chinese herbal tea with ginger everyday. You can buy the luo han guo at any Chinese provision shop or medicinal hall. All you need is half of one ball. Give it a quick rinse but don't clean the seeds as that's where all the goodness is. Cut a slice of fresh ginger (with skin), about half an inch thick and smash it like Martin Yan on Yan Can Cook - if you can't then just use the back of a heavy knife and whack the ginger a few times. Throw both ingredients into 2 litres of water and simmer for about an hour. All the goodness will come out. Cool and serve warm! If you don't have a cough, this is good for soothing the throat - good for teachers!!
And if you're recovering from flu, the mint and ginger tea would do good!
