Chinese: 在大腿前方内侧,髌骨底内侧端上两寸 (三支手指宽度),股内侧肌隆起处即是本穴. With the knee bent about 90 degrees, rest the palm on the kneecap and the thumb on the inner thigh; the thumb tip marks the point.

Point guide

Find & press

  1. Bend and landmark

    Sit with the knee bent about 90 degrees. Rest the palm on the kneecap and place the thumb on the inner thigh; the tip of the thumb lands on the vastus medialis bulge about three finger-widths above the medio-superior kneecap border. Feel for the soft muscle rise, not hard bone.

  2. Finger-press to dull soreness

    Massage the point with a fingertip until you feel a dull, slight soreness (酸胀). Keep the pressure kind. Sharp shooting pain means ease off and relocate on the muscle bulge.

  3. Rotate 3–5 minutes, both sides

    Maintain that pressure while rotating your finger on the point for three to five minutes. Then repeat on the other thigh. Chinese cue: 以指尖按揉穴位直至有酸胀感,以相同指力持续揉动穴位3-5分钟。两侧交替重复.

  4. Week-before rhythm

    Many people massage daily in the week before their period (月经前一周每日按揉本穴). Between cycles, a short daily press still works as a Blood-sea habit when a physician has suggested it.

  5. Stop cues

    Ease off if the press feels sharp, numb, or wrong. Mild ache that eases on release is common; sharp pain is a stop signal.

FAQs

Quick questions

Where is the Xue Hai (SP10) acupuncture point?

About two cun (three finger-widths) above the medio-superior border of the kneecap, on the vastus medialis bulge of the inner thigh. With the knee bent, palm on the kneecap and thumb on the inner thigh, the thumb tip marks the point. Chinese: 髌骨底内侧端上两寸,股内侧肌隆起处.

How do I know I found SP10?

The palm-on-kneecap and thumb-on-inner-thigh landmark usually lands on a tender spot on the vastus medialis bulge. Mild ache on press that eases on release is common; sharp pain means ease off and relocate.

How long should I press Xue Hai, and should it hurt?

Massage with a fingertip to a dull soreness (酸胀), then rotate for three to five minutes on each side. Sharp pain, shooting tingling, or numbness means ease off.

When should I massage SP10 for my period?

A common home rhythm is daily massage in the week before your period (月经前一周每日按揉本穴), plus both thighs each session. It is not a substitute for treatment if cycle symptoms keep returning.

What is Xue Hai (血海) used for at home?

Home press often supports cycle timing and Blood-related self-care on the Spleen channel. Self-press is a short habit between visits, not care for sudden heavy bleeding or severe pelvic pain. Seek urgent help if those appear.

Can I press SP10 every day?

Short, kind presses once a day for three to five minutes per side are fine for many people when a physician has suggested the habit. Ease off if the thigh stays sore or bruised.
