The law defines someone who is an unlicensed complementary and alternative health care practitioner as someone who:
(3) is engaging in complementary and alternative health care practices; and
(4) is providing complementary and alternative health care services for remuneration or is holding oneself out to the public as a practitioner of complementary and alternative health care practices.
