At what point did herbal medicine become this generalised?
A gentleman recently presented with chronic kidney disease. His renal function had declined to 38%. Prior to attending the clinic, he had been taking a combination of pre-made herbal pills: Eight Treasures Pills (Ba Zhen Wan) and Restore the Right Pills (You Gui Wan) for six months. At the commencement of this treatment, his kidney function had been 49%.
Combining pre-made formulas in this way reflects a lack of precise diagnostic differentiation and an over reliance on theoretical accumulation rather than structured clinical observation. In serious disease presentations, this approach risks obscuring the true pattern rather than clarifying it.
During his initial consultation, we were able to reduce the presentation to a single coherent formula structure - what we refer to as aligning the disease pattern with the formula pattern. This was the original intention of herbal medicine: restoring normal physiological function through accurate pattern recognition.
This process depends on careful questioning, observation, and palpation. When performed correctly, each clinical finding begins to reinforce the others until a single, coherent formula structure emerges.
Key Diagnostic Findings
- No Thirst or Veiling/DIzziness.
These findings immediately allow us to exclude a number of formula structures containing Alismatis Root (Ze Xie).
Additionalfindings included
- Poor appetite
- Vexation and agitation
- Abdominal bloating and distension
- Bowel movements occurring three to four times daily, soft, containing undigested food, without foul odour or stickiness
- Clear, frequent urination with nocturia two to three times each night
- A wet, turbid yellow tongue coating
Taken together, these findings both exclude and support specific herb combinations, progressively narrowing the diagnostic and herbal possibilities.
At this stage, the working structure begins to resemble a Dried Ginger (Gan Jiang) based formula. However, this must be confirmed through both abdominal palpation and tongue examination.
Abdominal and Structural Findings
Abdominal examination revealed marked distension accompanied by dry skin. There was also a distinct temperature differential, with the area below the umbilicus noticeably colder than the upper abdomen, reinforcing the indication for Dried Ginger.
Pulsations were palpable above the umbilicus, extending to the midway point between the the umbilicus and the xiphoid process. Within a Gan Jiang - based structures, this finding supports the inclusion of CinnamonTwig (Gui Zhi) or Poria (Fu Ling).
Importantly, there was no fixed, non-responsive spherical shape in the upper epigastrium, allowing formulas centred on Ginseng (Ren Shen) to be excluded.
Given the wet tongue coating and deep pulsations consistent with fluid accumulation, Poria remained clearly indicated alongside Dried Ginger.
The upper epigastrium demonstrated a non-specific, non-responsive fullness without a defined shape, consistent with obstruction by turbid fluids (dampness). Combined with the wet, turbid yellow tongue coating, this supported the inclusion of aromatic damp-transforming herbs such as Black Atractylodes Root (Cang Zhu) rather than White Atractylodes Root (Bai Zhu), as Black Atractylodes Root more effectively transforms and mobilises turbid dampness.
Formula Structure
The resulting prescription aligned precisely with Licorice, Dried Ginger, Poria, and Atractylodes Blend (Gan Jiang Ling Zhu Tang), a formula well recognised for presentations involving impaired kidney function.
The foundation of this prescription is Licorice and Dried Ginger Blend (Gan Cao GanJiang Tang).
Dried Ginger can be understood through the image of the sun. When the sun is strong, it radiates warmth downward and inward, warming the earth beneath it. When its warmth weakens, the ground becomes cold and wet. Within the body, Dried Ginger performs a similar function by directing warmth inward and downward, dispelling internal cold and restoring core metabolic activity.
When this descending warming function becomes weak, the gas level cools and water can no longer be properly warmed, steamed, and regulated. Symptoms then emerge, including abdominal distension without true fullness, skin that feels rough and dry, frequent urination, loose watery stools, and a sensation of cold in the lower abdomen.
As this warming and descending function continues to deteriorate, heat is displaced upward as counterflow, producing vexation and agitation affecting the Heart.
Throughout this entire process, there is often a persistent sense of urgency within the body's physiology. This highlights the essential role of Licorice (Gan Cao), which moderates, harmonises, and stabilises the strong pungent action of Gan Jiang, allowing warmth to be restored without force and physiological movement to recover without strain.
The addition of Black Atractylodes Root enables the body to properly transform and transport fluids. This becomes particularly important in presentations characterised by frequent urination or loose, watery stools. Similar to Unripened Bitter Orange (Zhi Shi), Black Atractylodes Root assists in appropriately distributing fluids between the Large Intestine and Bladder, helping to restore normal water metabolism and function.
Poria (FuLing) works synergistically with Black Atractylodes Root to regulate the movement of water through the Bladder and Large Intestine pathways, promoting effective drainage. This action complements the descending warmth generated by Dried Ginger and Licorice, helping restore core temperature and normalise fluid metabolism.
Clinical Outcome
Following three powdered prescriptions over six weeks, renal function improved from 38%to 59%.
Nocturnal urination resolved completely. Bowel movements normalised to once daily and became well formed. Appetite and thirst returned to normal.
The patient's dry skin improved, abdominal pulsations above the umbilicus disappeared, and the tongue coating cleared, indicating restoration of fluid transformation and internal warming.
Abdominal distension also reduced significantly, although it had not yet completely resolved. The lower abdomen remained slightly cooler than the upper abdomen, indicating that the underlying formula-disease pattern required further treatment.
Closing Reflection
This was ultimately a straightforward case once the diagnostic process was simplified through systematic exclusion and confirmation.
When questioning, observation, and palpation are integrated correctly, the formula structure becomes increasingly self-evident.
Complexity arises when theory is applied without precise clinical anchoring. This often results in over-layered prescriptions, unnecessary modifications, or combinations of pre-made formulas that lack a coherent structural rationale.
By contrast, when the disease pattern and formula structure are accurately aligned, treatment becomes both simpler and more precise, even in patients presenting with chronic or complex disease.
