Woodblock illustration from a work on 'Chinese' medicine by the 18th century Japanese physician Hara Masakatsu, published in 1807 (4th year of the Bunkwa era). The lung channel of hand taiyin is one of the Twelve Channels. It originates at zhongfu (Middle Palace) and terminates at shaoshang (Lesser Shang). There are altogether 22 acu-moxa locations on this channel, on both sides of the body, i.e. zhongfu (Middle Palace), yunmen (Cloud Portal), tianfu (Celestial Palace), xiabai (Clasping the White), chize (Foot Marsh), kongzui (Utmost Opening), lieque (Break in the Sequence), jingqu (Channel Ditch), taiyuan (Great Abyss), yuji (Fish Border) and shaoshang (Lesser Shang). It has a branch running from the back of the wrist to the tip of the index finger on the thumb side. The acu-moxa locations of the lung channel of hand taiyin are used to treat disorders considered to relate to the pulmonary system, such as coughs, asthma, sore throats, cold pain in the back and shoulders, pain in the inner part of the forearm, etc.
