Sondra The three yin meridians of the foot move Qi and blood and merge at a major confluence point in the lower leg. The primary acupoint that connects these three rivers is Spleen 6 (SP6), or the “three yin crossing” (Sanyinjiao).
The three rivers (meridians) at SP6 contain:
Spleen channel. The channel manages digestion and transforms food into Qi.
Liver channel. The channel ensures smooth flow of Qi and stores blood.
Kidney channel. This channel stores essence (Jing) and controls water metabolism.
Stimulating SP6 allows the practitioner to influence all three meridians simultaneously. The location is 3 cun (approximately 4 finger-widths) directly above the tip of the medial malleolus (inner ankle bone), on the posterior border of the tibia. Apply firm pressure with the thumb, massaging in circular motions for 1-2 minutes, or use acupressure to move stagnant Qi and blood.
Stimulating this acupoint relieves gynecological issues, supports digestion, resolves dampness, and calms the mind. SP6 is generally considered a forbidden point during pregnancy — it is traditionally avoided because stimulating it can trigger premature uterine contractions.
