CASE A: A mother comes in with a child complaining of flu-like symptoms. As a protocol to diagnosis, the physician needs to do an overall check up on the patient to confirm if the situation the boy is suffering from is really flu. Once the shirt of the child was removed, several bruises were noticed on his torso. The mother confirms that such marks came from what she called as cao gio, a supposedly herbal treatment that she confirms to be working especially for the tribe that she and her family belonged with. It is supposed to raise out bad blood thus improving circulation and healing. Nevertheless, this very treatment caused pain to the patient and practically worsened the symptom the child was already suffering from.
