What is rukhole ? As for mint, some beardies might eat a bit but none of my dragons really care for it. Try greens like mustard, collard, turnip, kale arugula.
Beardies often bite at green things [ that's why I can't have fake plants in my enclosure ] and will swallow some and spit other stuff out.
Beardies don't care too much for the very strong taste of mint but might eat a bit mixed in a salad. Use greens like turnip, mustard, collard, arugula, dandelion and kale but not spinach or swiss chard, they contain high amounts of oxalates.
