Nasal insufflation

The blowing of powdered medicinals into the nose. For example, chronic paranasal sinusitis (deep-source nasal congestion) can be treated with an insufflation of calcined and ground otolith (Pseudosciaenae Otolithum, 鱼脑石 yú nǎo shí) together with a little borneol (Borneolum, 冰片 bīng piàn) into the nose. Common cold with nasal congestion can be treated by insufflating finely ground centipeda (Centipedae Herba, 鹅不食草 é bù shí cǎo).
