Phyllanthus niruri or Dukung anak.

I have been looking for this wild herb for a long time. When we were young, my mother would send my siblings and I to collect by pulling these herb, roots and all. She boiled this for us to drink. I found this growing a in pot sharing another plant in Singapore.
We called this MA ZAI CHO. Phyllanthus niruri or Dukung anak.
