Thank you. The rooting powder and the gel both contain Indole-3-butyric acid. You might find this article interesting http://preparednessmama.com/natural-rooting-hormone/.
My mint all died during the rainy season. It was overgrown with weeds and completely drowned. My fault of course, so I was glad I found some on the market. You can probably just put in some water and it will root as well. Good luck experimenting.
