SP-10 Xuehai
SP-10 Xuehai (血海) is a point on the Spleen meridian. In TCM theory it is described as influencing the channel's qi, and it is traditionally used in the context of the whole pattern rather than as a stand-alone remedy. This page explains how to locate it, what the tradition says about it, and how to press it safely.
Location
Two cun above the superomedial corner of the patella, on the bulge of the vastus medialis muscle.
How to find it
Sit with the knee bent. Place the palm on the kneecap; the thumb rests at the upper inner corner. Slide the thumb two finger-widths up into the muscle bulge.
Traditional functions
- The "sea of blood"
- Invigorates and cools the blood
- Regulates menstruation and benefits the skin
Traditional uses
- Menstrual patterns in traditional practice
- Skin irritation and itching
- A tendency to bruise easily
- Thigh tension
How to press it
Press with the thumb for 1 minute, using a slow circular motion. The muscle can be tender.
Acupressure is generally a gentle practice. Use the pad of the thumb or finger, start with light pressure, and increase only to a comfortable level. A mild ache or warmth is common; sharp pain is a signal to ease off.
Safety
Avoid strong pressure during pregnancy, over varicose veins, or on an injured thigh.
How this is viewed today
SP-10 appears in trials for eczema, urticaria, and menstrual pain. Evidence is limited and often preliminary.
