Glusco works lah. But must take long term.
Stop for 3 months only, and my aching and stiff knee is back.
Ginger is often used for sprains and even slimming too.
Try slicing the ginger or grating it, soat the grated ginger in
chinese rice wine or their so called 'tei ta jiu' (chinese
medicinal wine for external use).
Use the grated ginger, wrap around the swolloen/sprain area with a
bandage for a few hours. (Like what the above ladies has
suggested.)
Or alternatively, soaked your feet in hot water with sliced
gingered.
For slimming, can try ginger powder in your bathtub of hot water,
soaked in it and hour, then wrapped yourself in your blanket to
sleep.
Dont rinse off.
Next morning, you can find your blanket all oily and yellowish cos
the ginger opened up your pores and sweat out the dirty stuffs in
your body.
