Chanca Piedra (Phyllanthus niuri) a 5ar inhibitor?


According to this study:

Chanca Piedra, which is very effective for kidney and gallblader stones, is also good at regrowing hair scalp thanks to its 5ar activity.

I am having a hard time understanding from this study whether:

  • this effect is significant when you consume the herb in a tea as opposed to the alcohol extract
  • this effect is systemic or localized to the scalp
  • the magnitude can be compared to Propecia
