A. “I insert needles into meridian lines of my child's body to help with pain relief.”: Inserting needles along meridian lines describes acupuncture, a traditional practice aimed at balancing energy flow. Acupuncture does not involve suction or heated containers placed on the skin. B. "I rub the edge of a coin lengthwise on my child's back when he is sick.": Rubbing a coin on the back refers to coining, also known as gua sha, which is used to release illness or bad energy. Coining produces linear marks rather than circular suction marks. C. “I sometimes place a bottle containing steam against my child's skin.": Placing a heated bottle or cup against the skin creates suction as the air cools, which is characteristic of cupping therapy. Cupping commonly leaves circular marks due to localized pressure and increased blood flow. D.
