Supports urinary system health.∞

Traditionally used to ease discomfort associated with acute urinary tract infection or blockage ∞

The source text describes Zhu Ling Tang for use when the body’s yin (functional moisture) is exhausted or inadequate. It’s important to recognize that there is a difference between healthy, functional moisture/body fluid (yin) that circulates, cools and moistens the body and pathological body fluid (dampness) that is out of circulation and simply accumulates and gets in the way.
In this situation, we see dampness trapped in the lower abdomen that has begun to heat up (damp heat). This is a common place for dampness to accumulate because it is the domain of the bladder and kidneys, and because fluid is heavy and tends to sink. It is the kidney’s job to process and eliminate old fluid. When this organ system is chronically weak, fluid will come in faster than it can go out, leaving an accumulation of turbid fluid. Over time, the liquid component of body fluid partially reabsorbs into the tissue and leaves the tiny particles of old cell debris and mineral deposits the body can’t use behind. This creates a thicker, more turbid fluid that is increasingly difficult for the bladder and kidneys to eliminate. This dampness becomes the perfect environment for infection and a host of other issues.
Traditionally, in Chinese Medicine, this formula has been widely used for people with infections or stones in the kidney/bladder system. The problem comes when the body doesn’t have the ability to fully flush out old fluid right away leaving an accumulation of thick dampness.
 Imagine two bodies of water, first is a small pond sitting in the sun in the middle of summer. It is alive with mosquitos, fish, algae and bacteria all thriving in this little hot, cloudy, closed ecosystem. Now imagine, this same area has a rushing creek that flows and twists and turns. This creek is fed by other channels of water and is in constant motion. There is life here, but the water is cool, clear and is a very poor incubator for bacteria or mosquitos. The same is true in the body: if that little sun baked pond is likened damp heat in the kidney/bladder system, it’s easy to understand how bacteria can gain a foothold to reproduce or how it might become thicker and more turbid over time.
This internal environment is a huge factor in recurrent urinary tract, bladder or kidney infections. Western medicine’s solution is to use antibiotics to kill the bacteria that have taken over the pond. Alternatively, staying with the pond analogy, Chinese medicine approaches this problem by draining the water and restoring the pond’s natural filtration system (your Kidneys).
Chinese medicine views stones as an extension of that same imbalance. Stones are formed when this dampness stays trapped for long enough and the clear fluid continues to reabsorb. The dense particles within the fluid have nowhere to go. The fluid here becomes more dense until ultimately these accumulations become hard stones. Depending on the individual body’s chemistry these stones can be made of different types of particles, but ultimately all need to be broken down and eliminated. Traditionally, Chinese medicine has a long history of using herbs intended not only to break down the accumulations and flush them out, but also to strengthen the kidney/bladder organ system and restore the damaged yin fluid in order to break this cycle and restore the body’s internal environment.
In addition to the Classical base formula, Zhu Ling Tang, we’ve included two herbs that are traditionally indicated to help unblock painful urinary obstruction or dribbling, clear damp heat, soothe the urinary tract, and help facilitate the passing of stones. After this pattern has cleared, one might consider further supporting kidney yang with Recharge..
