Have been using green bean powder with milk as mask for the last three days. My neighbour advises my mum to try this to reduce outbreak and not to rely too much on intake medicine (that’s me). The green bean powder is blended with chinese herbs, you can ask the chinese medical hall to blend them for you.
So i did some research at the taiwan yahoo and found 绿豆＋中药偏方 to read about the function. There are 2 other sites with DIY masks recipes, but all in chinese: MyChat and 美容diy.
