This is called Yin Sen in Khmer or Ren Sen in Chinese (pinyin). This plant is really useful for rabbits, and I would really thank my Malaysian friend(Hairil Tan) for telling me about this.
When you found out that your pregant rabbit doesn’t have enough milk for the baby, just give a few stalk of it to her. After 24 to 48 hours, then she will produce extra milk . I have been giving several stalks to my doe rabbits, and I have noticed that I could survive much more baby.
We also can cook it with pork, it is healthy green plant for both rabbits and human.
