Clinical Overview
In veterinary acupuncture practice, SP6 is one of the most versatile and multi-functional points, often referred to as the "Three Yin Intersection."
TCVM practitioners often include SP6 in protocols aimed at strengthening Spleen Qi, nourishing Blood and Yin, regulating menstruation and gynecological conditions, calming the Shen, and addressing digestive, reproductive, and mental-emotional well-being simultaneously.

Pinpoint Location
Anatomical Landmark
On the medial (inner) side of the lower leg, locate the medial malleolus (the prominent bone on the inner ankle). SP6 is 3 cun directly above the tip of the medial malleolus, posterior to the medial border of the tibia, on the soft tissue just behind the tibia. A quick way to locate it is by placing four finger-widths (your own fingers) above the tip of the medial malleolus, on the soft tissue just behind the tibia.
Primary Clinical Indications
- Diarrhea: Strengthens Spleen Qi to help the Spleen regulate digestion, addressing bloating, loose stools, and reduced appetite.
- Infertility: The "go-to" point for gynecological conditions, fertility, and reproductive health issues.
- Insomnia: Effectively treats sleep disturbances, restless sleep, and mental-emotional turbulence.
- Hind limb paralysis: Used for lower leg discomfort, cramps, swelling, tension, and hind limb weakness/paralysis.
- Stress & Anxiety: Calms emotional turbulence, irritability, and promotes relaxation.
Recommended Point Pairings
In clinical veterinary acupuncture, SP6 is often paired with other digestive, reproductive, and multi-system support points depending on presentation.
Frequently paired with ST36 (Zusanli), the master point for GI tract, to strengthen Spleen Qi and regulate digestion.
Often combined with LIV3 (Taichong),肾俞 (BL23), and REN4 (Guanyuan) for fertility, dysmenorrhea, irregular cycles, PMS, and postpartum recovery.
May be integrated into multimodal support strategies involving acupuncture, nutrition, and veterinary medical care for urinary disorders and pelvic issues.
Modern Veterinary Interpretation
From a modern veterinary rehabilitation perspective, SP6 is one of the most extensively researched points in the literature, with studies finding it effective for pain relief and multi-system regulation.
Integrative veterinarians may include this point within broader digestive, reproductive, urinary, stress/anxiety, and hind limb weakness-support plans involving acupuncture, electroacupuncture, and medical management.
Safety & Needling Notes
Professional Veterinary Use
Acupuncturists typically needle SP6 to a depth of about 0.5 to 1.5 cun, depending on body type and treatment strategy. Needle perpendicularly 0.5–1.0 cun. Patients often feel a dull or heavy sensation that may radiate up or down the leg, indicative of qi activation in the channel.
Gentle Acupressure Guidance
Pet owners exploring supportive acupressure can use gentle, firm pressure on this point for 3–5 minutes daily on both hind legs. Studies found SP6 acupressure delivered by trained personnel significantly decreased pain intensity immediately after intervention, with pain relief remaining up to 3 hours.
