    Master Tung's Three Rivers (San Jiang) are three lines of points, one along the midline below each spinous process from L1 to S2 with the another two either side 3 cun lateral to the midline from L2 to S2. They are pricked to bleed a spot of blood.
    They relate to the water phase and Kidneys and are indicated for lumbar pain and conditions of the abdomen, bowels and uterus. Those 3 cun from the midline can also be used for sciatica and as distal points pain of arm, elbows or shoulders (McCann, 2014, Pricking the Vessels).

    In Tibetan medicine:
    Edelweiss flowers are burnt in cones like moxa over crushed garlic at this point as a urinary bladder point to treat urinary stones, urine retention and frequency of urine.
    There are a further two points below this on the sacrum which are the reproductive fluids point, to treat premature ejaculation and impotence, and the downward cleansing mLung point that treats incontinence of the bowels, constipation and mucus diarrhoea (Bradley, 2000: Principles of Tibetan Medicine)
