I had forgotten about "Gypsy Cold Care," Caleb. Yes, that was of help.
Punkin, I believe I should recommend anise hyssop, aka. licorice mint (Agastache foeniculum). I grew the plants 10 years ago and then found reference to its safety in a UK herb book. So, I gave all those plants away - they are quite ornamental.
After 7 or 8 years casual research, I came to the conclusion that no other source was questioning the safety of this plant. It seems to me that the concern was with licorice, itself. Licorice acts as blood thinner, apparently, not licorice mint, an entirely different plant.
By itself, and especially in combination with lemon verbena, licorice mint is a favorite. And importantly, I can grow it!! Whether it will grow well in eastern Texas

, but I suspect so.
Don't allow it to reach the stage when the swallowtails show up before harvesting some for tea. The seed seems to germinate so easily, you should have plenty of extra plants for the swallowtails. And be advised if you do grow it, it self-sows vigorously.
