The water in your toilet cistern is usually the same fresh, clean water as anywhere else supplied in your house!
(unless you have a separate supply to your toilet, or maybe use recycled water?)
The only time it gets "Yucky" I suppose is when the water is in the toilet bowl itself, and I'm not suggesting you put your driftwood in the toilet bowl!
This way you're saving water, surely a good thing?
