1. High incidence of thyroid nodules has become common in health checks – understanding the root cause is essential for proper care

What is a thyroid nodule? Perspectives from Western and traditional Chinese medicine

1.1 Western medical perspective:
A nodule is a localized mass formed by abnormal proliferation of glandular cells. The thyroid gland is located in the front middle‑upper part of the neck, shaped like a butterfly or a shield. It is the largest endocrine gland in the human body. A normal thyroid gland is thin and not visible to the naked eye or palpable. A thyroid nodule is essentially a localized mass caused by abnormal cell proliferation within the thyroid gland. It is a common chronic endocrine condition. In the early stages, most people experience no obvious discomfort, and the nodule is often discovered incidentally as a firm, painless mass during a routine ultrasound examination. As the nodule slowly develops, some individuals may experience neck swelling or a sensation of a foreign body when swallowing. In severe cases, it may compress the airway, causing voice changes or breathing difficulties. A small proportion of nodules may exhibit functional abnormalities leading to hyperthyroidism. With the widespread availability of health check‑ups in recent years, the detection rate of nodules has been rising year by year. The detection rate among young and middle‑aged women is significantly higher than that among men. Staying up late, emotional stress, and irregular daily routines are key triggers for the high incidence of nodules in modern populations.

1.2 Traditional Chinese medicine perspective:
Nodules fall under the category of "gall disease" (ying bing), with the core root cause being qi stagnation in the liver and gallbladder leading to phlegm congealing. In the TCM system of pattern differentiation, thyroid nodules are classified as "gall disease." Director Yu Huafen of Tiandao TCM, based on ancient TCM classics and clinical experience, has proposed that thyroid conditions are closely related to the liver, gallbladder, and Sanjiao (Triple Energizer) meridians.

TCM emphasizes that "emotional disharmony leads to liver qi stagnation." Long‑term suppressed emotions, anxiety, and unresolved stress can cause qi stagnation in the liver meridian. The liver and gallbladder are internally‑externally related. When qi is stagnant, the transportation of body fluids becomes disordered. Phlegm‑dampness stagnates in the thyroid meridians at the front of the neck. Qi stagnation, blood stasis, and phlegm congealing intertwine and accumulate, eventually forming nodules. At the same time, the thyroid gland is located in the area through which the Sanjiao meridian runs. Both the Hand‑Shaoyang Sanjiao Meridian and the Foot‑Shaoyang Gallbladder Meridian are associated with the Shaoyang qi mechanism. When the Sanjiao's function of transporting fluids is impaired, turbid pathogens block the glandular vessels, further accelerating nodule formation. Therefore, TCM management of nodules should not focus only on the local neck area, but also address the overall qi movement of the liver, gallbladder, and Sanjiao.


 

2. Five common triggers for thyroid nodules

• Emotional factors: Long‑term emotional suppression is the primary trigger for nodules. Clinical surveys show that more than half of patients with nodules have lived for years in a state of anxiety, irritability, or depression. Under the dual pressures of modern work and family life, negative emotions cannot be released in time, continuously depleting liver qi. Qi stagnation is the initial trigger for nodule formation and a key driver of nodule enlargement.

• Imbalance between diet and iodine intake: Iodine is a basic raw material for thyroid hormone synthesis. Long‑term excessive iodine intake or iodine deficiency can disrupt the normal secretion rhythm of the gland, inducing compensatory hyperplasia and nodule formation. Blindly consuming large amounts of high‑iodine seafood for a long time, or adhering to a deliberately iodine‑free diet, is not conducive to thyroid stability.

• Lifestyle strain and overwork – depleting qi and blood in the internal organs: Long‑term sleep deprivation, overwork, and lack of rest continuously consume the body's qi and blood. The transport function of the internal organs declines, making it easier for phlegm‑dampness and blood stasis to stagnate in the neck gland meridians, accelerating nodule formation.

• Constitutional predisposition and environmental factors: Some individuals have a constitutionally weaker internal organ function, with an inherent deficiency in the transport capacity of the liver and gallbladder. When combined with external factors such as environmental radiation or chemical irritation, the risk of nodule development increases.

• Secondary to other thyroid gland conditions: Chronic thyroid inflammation such as Hashimoto's thyroiditis or subacute thyroiditis repeatedly irritates the gland. During the repair and hyperplasia process of the gland tissue, nodules may also easily form.
  
  
   

3. Tiandao TCM Qiteng Therapy: an external approach to managing thyroid nodules based on TCM qi‑blood theory

3.1 Core TCM theoretical basis of Qiteng Therapy

Qiteng Therapy is an external comprehensive treatment independently developed by Tiandao TCM based on traditional qi‑blood theory. It follows the ancient TCM principle of qi‑blood circulation: qi and blood throughout the body rely on the meridians for distribution. When qi flows smoothly, blood circulates freely, and stasis is less likely to form. Once qi stagnates, blood stasis and phlegm‑dampness accumulate, leading to meridian blockage and the formation of hard masses. A thyroid nodule is precisely a tangible manifestation of qi stagnation, blood stasis, and phlegm congealing in the meridians of the front of the neck.

3.2 Advantages of external treatment: bypassing oral administration, reducing the burden on spleen and stomach metabolism

Traditional oral Chinese herbal medicine must be digested and absorbed through the gastrointestinal tract, which some individuals with weak spleen and stomach function may not tolerate well. Qiteng Therapy is a purely external treatment. The herbal properties penetrate through the sweat pores on the body surface to take effect, without passing through the digestive tract. It does not add extra burden to the spleen, stomach, liver, kidneys, or nervous system. This makes it suitable for patients with nodules who have a weaker spleen and stomach or who cannot tolerate long‑term oral medication.

3.3 How Qiteng Therapy works in managing thyroid nodules

Step 1: Whole‑body high‑temperature herbal steaming – opening the pores and unblocking superficial meridians.
The therapy consists of two main stages. In the first stage, the patient receives whole‑body steaming with high‑temperature herbal steam. The warm environment opens the sweat pores, accelerates blood circulation and metabolism throughout the body, unblocks superficial meridians, helps expel superficial cold‑dampness and turbid pathogens, raises the body's yang qi, and improves the constitutional tendency toward cold‑dampness, thereby reducing the source of phlegm‑dampness formation at a systemic level.

Step 2: Targeted high‑temperature herbal application on the neck – penetrating to resolve the stagnant lesion in the gland.
After whole‑body steaming, precise high‑temperature herbal application is performed on the neck area corresponding to the thyroid nodule. The warm herbal action reaches the deep fascia and glandular tissue at the front of the neck through the opened pores, gradually breaking down the stagnant waste, phlegm‑dampness, and hard masses adhered to the thyroid meridians and interstitial tissues. The broken‑down turbid waste is converted into fine particles and expelled from the body through the sweat pores, forming scabs on the skin surface. When the scabs naturally fall off, this indicates that localized turbid waste is being gradually eliminated.

3.4 After the expulsion of turbid waste, the body's self‑healing capacity is activated, and the microcirculation of the gland is supported

As the stagnant waste in the neck is continuously expelled, the meridians at the front of the neck gradually become unblocked. Fresh qi and blood can continuously nourish the thyroid gland tissue. The local ischemia and hypoxia of the gland are improved. The stiff and hardened diseased tissue is gradually activated and relaxed. The internal microcirculation of the gland is optimized. The stagnant environment that favors nodule growth is improved, achieving an overall therapeutic effect.
