The historical accounts suggest that the discovery and formalization of 11.10 Mu Huo [木火穴] – Wood Fire as a “fixed” point (Ding Xue) was crystallized during the treatment of Lon Nol. Prior to this case, many points in the Tung system were treated as ‘undetermined’ (Bu Ding) or ‘reaction points,’ where the practitioner would look for specific physical markers—such as blue veins, dark shadows, or sensitive nodes—to determine where to needle.
Point 11.10 Mu Huo [木火穴] – Wood Fire, located on the middle finger, was one such point effectively used to address the underlying “Internal Wind” and “Phlegm Fire” associated with Lon Nol’s hemiplegia. Through repeated, intensive needling of the middle finger over the course of the 22-day first mission, the anatomical location and specific clinical protocol for this point were formalized. It was during this time that the name “Mu Huo” (Wood Fire) was applied, reflecting its theoretical ability to harmonize the Liver (Wood) and the Heart (Fire).
Technical Specifications of 11.10 Mu Huo [木火穴] – Wood Fire
Point 11.10 is located on the dorsal side of the middle finger, specifically at the center of the distal interphalangeal joint. This location is strategically significant because, in the holographic mapping of the hand, the middle finger corresponds to the central axis of the body and the brain.
| Feature | Description |
| Zone | Zone 1 (Fingers) |
| Location | Dorsum of the middle finger, center of the junction between the 2nd and 3rd phalanx Hu Wen Zhi adds three points on the second, fourth, and fifth fingers at the same location. |
| Primary Indication | Hemiplegia (stroke paralysis), limb numbness, Wood-Fire imbalance |
| Needle Technique | Dorsum of the middle finger, center of the junction between the 2nd and 3rd phalanx |
| Reaction Area | Heart and Liver |
A critical component of the “discovery” of 11.10 Mu Huo [木火穴] – Wood Fire was the refinement of its needle retention protocol. Master Tung observed that, because the point is highly stimulating and targets deep neurological pathways, overstimulation could deplete the patient’s Yuan Qi (Original Energy). He developed a specific, diminishing retention protocol that was meticulously applied during Lon Nol’s recovery.
- Initial Treatment: Retention of 5 minutes to initiate the movement of Qi and Blood.
- Second Treatment (approx. 5 days later): Retention of 3 minutes to maintain progress without exhausting the patient.
- Third Treatment (approx. 10 days later): Retention of 1 minute, serving as a subtle “reminder” to the nervous system.
This protocol reflects a sophisticated clinical insight into the management of chronic stroke patients, where the body’s self-healing capacity must be carefully balanced against the force of the medical intervention.
Theoretical Foundation: The Wood-Fire Axis
The naming of point 11.10 as “Mu Huo” is a direct reference to its energetic function in the Five Fases (Wu Xing) theory. In traditional East Asian medical theory, a stroke is often the result of “Liver Wind” rising. The Liver belongs to the Wood (Mu) element. When Wood becomes overly active, or Yin is deficient, it can generate Internal Wind that carries Heat—associated with the Fire (Huo) element—upward to the brain.
Master Tung’s choice of point 11.10 for Lon Nol was based on the point’s location on the middle finger, which corresponds to the Heart channel in Tung’s acupuncture.
