Turning you orange is definitely not my same experience, then again i took a different product so who knows why that would happen.
The product you used was nettle leaf, right? I used organic nettle leaf from Frontier and brewed it into a concentrate. I used just enough water to cover 1 cup of nettles and it made a 6 oz concentrate so dark it was almost black. I later switched to a nettle tincture that was so concentrated it was black. I was using it as a calcium source when I didn’t tolerate dairy, but got far too much beta carotene as a result.
