Understanding Dry Mouth
Dry mouth – or xerostomia – is a common side effect of cancer treatment, especially radiation, chemotherapy, and certain medications. It can make eating, swallowing, and speaking uncomfortable, and may increase the risk of cavities or oral infection.
From a holistic perspective, saliva reflects more than hydration. It’s a marker of the body’s vitality and yin – the nourishing, cooling aspect that supports internal fluids. When yin becomes depleted, the mouth and throat feel dry, digestion may weaken, and sleep can be disrupted.
How Acupuncture Can Help
Acupuncture offers a safe, non-pharmaceutical way to support salivary function and comfort. Thin, sterile needles placed at specific points send signals through the nervous system that activate the salivary glands.
Functional MRI studies have shown increased brain activity in regions that regulate saliva production after acupuncture treatment.
In Chinese medicine, this process replenishes yin and restores harmony between the body’s organ systems. Over time, acupuncture can reduce dryness, improve taste, and make eating and speaking easier.
