Although the Passion Flower Poison Antidote that had been in the possession of Gung Sheun Tze and/or Kau Cheen Chek was lost, the Indian Monk and Wong Yung were able to save Yeung Gor by using the Deun Cheung Grass, which was a natural antidote to the Passion Flower Poison. That makes me wonder: was the original antidote that Gung Sheun Tze/Kau Cheen Chek had just Deun Cheung Grass, or was it some other compound (made of different ingredients) that could also cure Passion Flower Poison?
