Chanca piedra tea vs tincture

"According to Mrs Chang tinctures work better for the liver whereas teas are better for the kidneys.

I live in Brazil, and although Chanca piedra is commercialized all over the world, it is a Brazilian herb and I bought a 250ml bottle of Chanca Piedra Tincture and paid the correspondent of 4 dollars."


Good info, but who's Mrs. Chang? Tweet
