Bunga kantan is used widely in Penang-style asam pedas...but difficult to get in Europe, US and Australia.
An Indonesian friend, shared with me, this recipe to remove uric acid. I have used it and it works. Cheap and effective method for gout sufferers.
Take 3 shoots of Bunga Kantan (ginger flower – (as used in our famous Asam Laksa). Boil it in 4-5 litres of water. Reduce it till it’s down to about 3 litres. Use it as your daily intake of water.
