Torch flowers or Bunga Kantan are in season at present and are sold quite cheaply. I bought mine at RM1 for 3 stalks. When it is not in season one stalk can fetch up to RM2.50.
The lady at the market who sold them to me shared a herbal tip for these lovelies. It seems that boiling two of the flowers for about 10 minutes or so and drinking the concoction will help treat problems with sore leg muscles and joints. The measurement is to boil two flowers in about half a litre of water for 10 to 15 minutes. Then you can drink the concoction several times a week.
