    Notes:
    Ling Shu Ch. 21, On Cold and Heat Diseases, mentions this point and its connection with the Hand Yangming Large Intestine channel in tooth decay. Unschuld (2016) says that if there is an aversion to cold the channel is to be supplemented, if not it is to be drained. Wu & Wu (2010) say it should be drained at this point and the channel purged if the arm experiences aversion to cold.

    This point would also be on the upper trajectory of the Chong mai in Jeffrey Yuen's descriptions (Yuen, 2005, The Extraordinary Vessels).
