Category Test - Herbs Intro Final

Zhi Ban Xia (pinelliae rhizoma) belongs to which category?
Warm Herbs that Transform Cold-Phlegm are used for copious, thin, clear or white phlegm. These herbs are warm and acrid. Because "the Spleen is the source of phlegm and the Lung is the container of phlegm," these herbs tend to enter these two channels. These herbs are warm and drying; use caution in cases of yin deficiency.
Zhi Ban Xia transforms phlegm, resolves phlegm nodules, and subdues rebellious Stomach qi (nausea, vomiting, morning sickness). Ban Xia is toxic in its raw form. It's prepared by stir-frying it in ginger juice.
