I have passed green stones, when I used clear oils like Almond Oil, Macadamia Nut Oil and coconut Oil....
How did the green color come, when I did not use the famous green Olive Oil.
Also, the shaped of stones vary all the time. At times, I have passed longish stones. ( pencil size in diameter). other times I passed grape sized stones.
Its amazing and mysterious to me. Post us abt lab analysis. Even if they say. it's not stones, I will continue to flush.....
