Why do companies put beeswax on hemp wicks? Is there anything else that is safe to use on a hemp wick instead of beeswax?

The use the beeswax to help keep the hemp wick from burning too fast or burning out.   The wax is natural so this is the gimmick to use the hemp wick as a better way to light your bowl.

If you want true flavor, consider using a vaporizer like the Silver Surfer.
