The training in TCM in the US by and large gives short shrift to moxibustion, and this is tragic. Many, and perhaps most TCM colleges, train their students only minimally in moxibustion. Across the US many student intern clinic, if they use moxa at all, use only indirect smokeless moxa poles. So much more than that is possible with mugwort. Moxa as a therapy is of immense benefit, and you owe it to yourself to investigate it more closely.
