The Yang Qiao Mai Vessel or the Yang Stepping Vessel, like the Yin Qiao Mai Vessel, originates in the heel. However, it absorbs excess Yang Qi from the main channel in the Head, whereas the latter absorbs excess Yin Qi in the abdomen. Yin is slack, so Qi is able to sink in Yin Excess, and Yang is tight, so Qi is unable to move freely in Yang Excess. Pathology with the Yang Qiao Mai is seen particularly in the head.
The path of the Yang Stepping Vessel connects multiple channels and Vessels along the way. Firstly, the Vessel starts at the heel, follows its path to the bone near the external part of the ankle at point BL-62 Shenmai and reaches the point BL-61 Puncan towards BL-59 Fuyang. Next, the point G.B.-29 Juliao connects the upper thigh and the hip, continuing with the S.I.-10 Naoshu which connects the Small Intestine channel and the Yang Qiao Mai Vessel. Then, the path reaches the point L.I.-16 Jugu which connects the Large Intestine and the shoulder, and the point L.I.-15 where the Large Intestine connects to the Triple Burner.
The Large Intestine channel then connects to the Stomach channel with the point S.T.-9 Renying, and reaches the Directing Vessel at S.T.-4 Dicang. The path then continues to the ST-3 Juliao on the Stomach channel and to the point ST-1 Chengqi Directing Vessel. Ultimately, the path reaches the inner corner of the eye at BL-1 Jingming where the channels of the Small Intestine, the Stomach and the Bladder connect. The path ends over the skull at the point G.B.-20 Fengchi, which is located at the back of the ear.
Absorbing excess from the head
The Excess of Yang can cause mental problems including manic- depression and agitation especially with the presence of Phlegm. According to ancient texts, fullness occurs due to fear of ghosts and the longing for a dead relative. The opening points BL-62 and S.I.-3 are used with the coupling points Du-19 Houding, P-7 Daling, L.I.-4 Hegu, Ren-15 Jiuwei and LIV-3 Taichong.

Back pains must be solely unilateral and in a full state to use the Yang Stepping Vessel in treatment. The points include the BL-62 and the S.I.-3 in conjunction with the local points.
The point G.B.-29 Juliao affects the Bladder and Gall bladder channels that reside in the hips. Because of this, hip pain is treated with the points BL-62 Shenmai, S.I.-3 and ultimately the point G.B.-30 Huantiao.
Urinary problems manifest as pain and Dampness in the urinary passages. The points used to treat these include; the BL-62 Shenmai and S.I.-3 Houxi connected with the BL-63 Jinmen, BL-59 Fuyang, Ren-3 Zhongji and SP-9 Yinlingquan.

This vessel can be used for the Bi Syndrome in a full condition, where the wind causes the muscles to spasm. The points used in this treatment include; BL-62 and S.I.-3 aspace with G.B.-20 Fengchi, Du-16 Fengfu and BL-12 Fengmen.
In Hemiplegia, the wind does not only attack the muscles, but also paralyzes them.
