My aunt asked me to try this Nan Fei Leaves (南非叶), she said her friends tried and found that it can actually cure cough. Another cough remedy? then I must try lar, no harm trying mar, since i cough for so long already.
She showed me a newspaper article about this Nan Fei Leaves (南非叶). After I read the newspaper article (if you know chinese, click
here to read about the article.), this article does not mention anything about curing cough, but apparently this Nan Fei Leaves has antioxidant that can prevent cancer and also very good for ppl who has high blood pressure and high cholesterol. Wow...
Anyway, my aunt asked me to try as she said it really cured her friend's cough. Ok ok, let's try then. How does Nan Fei Leaves looks like?

Nan Fei Leaf

wash it, there's about 15 leaves here.

boil a pot of water, when the water boils,
put in the Nan Fei Leaves and turn off
the fire. Cover it for a while.

it taste a bit bitter. drink as much as u want.
According to the newspaper, this leaf is best to eat raw as the heat might lower down the antioxidant. It is best to eat with green apple, blend green apple with this leaf and drink the juice (prevent cancer). I think this is very good especially for old people. A lot of ppl already start planting this at home. If you have high blood pressure or high cholesterol, you might want to try this out. Even you don't have high blood pressure or high cholesterol, you can also try it out as it prevent cancer.
As for the cough, I'm not sure it works or not, as i cough on and off one. hehe, let me try to drink a few more times first then only i let you know. Where to get the plant? Well, i also dono, hehe, maybe you can start by asking your neighbors around, it's a very common plant, maybe your neighbors has it, who knows right?
