Han Lu (Cold Dew)

Han Lu (Cold Dew) in Traditional Chinese Medicine: A Deep Dive into the Large Intestine, Stomach, and Bladder

In Traditional Chinese Medicine (TCM), the cycles of nature and the changing of seasons have long been acknowledged to influence the state of our health. One particular seasonal node, known as 'Han Lu' or Cold Dew, marks the transition from the milder temperatures of early autumn to the colder onset of late autumn. As the earth prepares for winter's embrace, the dews that form during night become colder. This article will delve into the significance of Han Lu and its implications for three pivotal organs in TCM: the large intestine, stomach, and bladder.

Han Lu's Timing and Energetics:

Typically falling around October 8th to 23rd, Han Lu witnesses a shift in the energies from Yang (warm and active) to Yin (cool and passive). During this period, the Qi (life force) of living beings starts to contract and move inwards, focusing on preserving and storing energy for the impending winter.

The Large Intestine during Han Lu:

The Large Intestine, in TCM, is not just a vessel for waste elimination. It is also an organ of transformation, taking in the "impure" and transforming it into the "pure."

• Role in TCM: As part of the Metal element, the large intestine works in tandem with the lungs. During Han Lu, the lungs and large intestine need extra support, given that dryness and coldness can impact these organs.

• Implications during Han Lu: Dryness can lead to constipation. To support the large intestine, one should consume moistening foods like pears, sesame seeds, and tofu.

The Bladder during Han Lu:

TCM views the bladder not just as a storage unit for urine, but also as a part of a deeper physiological system connected with the Kidney.

• Role in TCM: As part of the Water element, the bladder's primary role is to store and excrete urine. It also plays a pivotal role in Qi transformation.

• Implications during Han Lu: Cold weather can challenge the bladder, leading to frequent urination or sensations of coldness. Consuming kidney-beans, black beans, and warming teas like cinnamon can support bladder health during this season.
  
  Seasonal Practices for Han Lu:

• Dietary Adjustments: Include warmer foods, reduce cold and raw foods. Introduce more root vegetables and warming spices into your meals.

• Exercise: Qi Gong and Tai Chi are excellent to ensure the smooth flow of Qi and blood during this time. Morning exercises help invigorate the Yang energy.

• Acupressure: Stimulating points like ST36 (Stomach 36) can help in bolstering the digestive system and overall energy.

Conclusion:

Han Lu, the Cold Dew season, is a gentle reminder of nature's cycles and the impending cold of winter. By understanding the needs of our organs – the large intestine, stomach, and bladder – during this transitional time, we can adapt our lifestyles to maintain balance and health in harmony with the season. Embracing the wisdom of Traditional Chinese Medicine during Han Lu ensures a smoother transition into the deep winter months that lie ahead.
