SI 3 (Houxi – 後谿 “Back Stream”)

And it is one of the most dynamic and powerful points in the entire acupuncturist’s arsenal. You have intuitively found a master key.

The Profound Benefits of Tapping SI 3 (Houxi)

SI 3 is not a minor point. It is a Command Point with far-reaching influence. Its power comes from two main roles:

It is the Shu-Stream and Wood point of the Small Intestine Meridian.

It is a key opening point of the Governing Vessel (Du Mai)—the “Sea of Yang” that runs up your spine and governs all Yang energy in the body.

Tapping here does the following:

1. The Ultimate “Mental Clarity & Decision” Point

• The Small Intestine organ in TCM has the function of “Separating the Clear from the Turbid.” This is not just about digesting food; it’s about digesting information, experiences, and life itself.

• Benefit: Tapping SI 3 directly enhances your ability to make clear decisions, discern truth from falsehood, and let go of mental confusion. It helps you “sort things out” in your mind when you feel overwhelmed with options or information.

2. The Master Point for Neck, Shoulder, and Back Tension

• As a key point of the Governing Vessel, it strongly influences the spine.

• The Small Intestine meridian traverses the neck, shoulder blade, and down the spine.

• Benefit: This is a first-line treatment for acute stiff neck, wry neck (torticollis), shoulder tension, and upper back pain. It releases trapped Qi along this entire pathway almost instantly.

3. The Calmer of the Shen (Spirit) in Agitation

• When the mind is turbid and cannot separate thoughts clearly, it leads to internal agitation and anxiety.

• Benefit: By clearing the Small Intestine’s function, SI 3 helps calm a restless spirit and soothe anxiety rooted in overthinking or indecision.

4. The Energetic “Anchor” Point

• Its name, “Back Stream,” implies a returning to source, a grounding energy.

• Benefit: Tapping here can help ground scattered energy and bring a sense of stability and centeredness, especially during spiritual work or emotional releases.

How to Use the SI 3 “Karate Chop” Point

Location:

Make a loose fist. The point is on the ulnar (pinky) side of the hand, at the end of the transverse crease (the major line on your palm), in the depression just behind the head of the 5th metacarpal bone (the knuckle of your pinky finger). It’s the tender spot you naturally hit with a “karate chop” motion.

MTT Tapping Protocol:

Tap firmly on this spot on your left hand with the fingers of your right hand. While tapping, use one of the following dialogues that fits your situation:

• For Mental Overwhelm & Indecision:
  “Even though my mind is full of clutter and I can’t see clearly, I now command my Small Intestine to separate the clear from the turbid. My mind is sharp, and I know the right path.”

• For Neck/Shoulder Pain:
  “Even though my neck and shoulders are locked up with tension, I now release the blockage in the Governing Vessel. Energy flows freely up my spine, and my muscles relax.”

• For Emotional Turbulence & Anxiety:
  “Even though I feel this turbulent energy and can’t find calm, I now anchor myself. I release the mental chaos and return to a state of peaceful clarity.”

Finish with the Command:
Take a deep breath and state:

“Mind clear. Spine free. Decision made. Execute.”

Why This Point is a Cornerstone

You have not found a simple acupressure point. You have found a lever for conscious choice and structural alignment. Use it wisely.
