The Deleterious Effects of Coffee: A Chinese Medicine Perspective

The Deleterious Effects of Coffee: A Chinese Medicine Perspective

How Excessive Heat, Dampness, and Stimulation Are Impacting Health and Vitality

Within Chinese Medicine, the balance and flow of qi (vital energy; qì; 气) and the preservation of yuan qi (original qi; yuán qì; 元气) and jing (essence; jīng; 精) are fundamental to maintaining health and vitality. Maintaining, preserving, and even restoring these fundamental reserves is a daily practice, and paramount to that is understanding how the choices we make on a daily basis—from lifestyle to diet—impact the balance between and our reserves of qi, yuan qi, and jing. One choice that many make daily is the consumption of coffee.

Coffee, Heat, Dampness

Coffee is a stimulating beverage that, from a Classical Chinese Medicine (CCM) and Traditional Chinese Medicine (TCM) perspective, introduces excessive Heat (Rè; 热) into the body. This is due to its inherent warming and stimulating nature, which can introduce and exacerbate conditions of internal Heat, particularly Liver Fire (Gān Huǒ; 肝火) and Stomach Fire (Wèi Huǒ; 胃火). Liver Fire is the excess of Heat in the Liver, leading to symptoms such as irritability, headaches, and red eyes, while Stomach Fire can cause heartburn, excessive hunger, and bad breath. Both conditions reflect significant imbalances that disrupt the body’s harmony and overall health.


Excessive Heat manifests in various forms, including irritability, restlessness, insomnia, and inflammatory conditions. Over time, the accumulation of Heat can lead to more serious imbalances, such as chronic stress, anxiety disorders, and digestive issues. Additionally, the body’s continuous struggle to counteract this excess Heat depletes yin fluids, further exacerbating the imbalance by creating a condition known as yin deficiency heat (Yīn Xū Rè; 阴虚热).

Yin Deficient Heat

Yin represents the cooling, moistening, and nourishing aspects of the body. When Yin is depleted, it can no longer adequately counterbalance the yang (heating) aspects, leading to a state of disharmony. The larger consequence of this disruption is a compromised ability to maintain and restore vital reserves of yuan qi and jing. When these essential energies are depleted, it leads to a weakened immune system, reduced vitality, and accelerated aging. The body’s capacity to heal, regenerate, and resist disease diminishes, setting the stage for a host of chronic ailments.

Additionally, coffee has a drying effect, which further depletes the body’s yin fluids. As Yin becomes increasingly deficient, the body further loses its ability to cool and nourish itself, exacerbating the vicious cycle of Heat and dryness. This condition is known as yin deficiency heat, or simply as deficient Heat.

Yin deficiency can impact overall fluid balance, leading to symptoms such as dry skin, dry eyes, and scanty urine, further highlighting the importance of maintaining Yin for holistic health.


In addition to generating Heat, coffee contributes to the formation of Dampness (Shī; 湿). Dampness refers to a pathological condition where fluids accumulate and stagnate, leading to a feeling of heaviness, sluggishness, and digestive issues. While coffee’s diuretic effect might initially seem to counteract Dampness by promoting urination, this effect can also weaken the Spleen and Stomach, the organs responsible for fluid metabolism, thereby exacerbating Dampness over time. By weakening the Spleen and Stomach, coffee exacerbates Dampness, undermining the body’s ability to properly digest and assimilate nutrients, further compromising overall health.

Dampness becomes pathological as it obstructs the flow of qi and blood, leading to various health issues. When fluids accumulate and stagnate, they create a toxic environment within the body. This stagnation can manifest as bloating, lethargy, a heavy sensation in the body, and even joint pain.

Over time, Dampness can lead to more severe conditions such as edema, chronic sinus congestion, and digestive disorders, and worse.

Who is fair trade coffee fair to?

Depletion of Yuan Qi and Jing

Yuan qi, or original qi, is the fundamental energy that we inherit from our parents at birth. It is stored in the Kidneys and is finite, meaning that it can be depleted but not replenished. Jing, or essence, is closely related to yuan qi and represents the body’s constitutional strength and vitality. Both yuan qi and jing are crucial for longevity and overall health.

The stimulant properties of coffee can lead to the excessive use of the body’s energy reserves. This constant stimulation forces the body to operate beyond its natural capacity, leading to the gradual depletion of yuan qi and jing. Over time, this can result in chronic fatigue, weakened immunity, and a decline in overall health.

Furthermore, the Kidneys, which store both yuan qi and jing, are particularly affected by the regular consumption of coffee. The Kidneys are considered the foundation of vitality, and their depletion can manifest in symptoms such as lower back pain, weak knees, dizziness, tinnitus, and premature aging.

Coffee, Loss of Vitality, and Aging

Coffee’s impact on yuan qi and jing has profound implications for vitality and aging. Yuan qi and jing are considered the essence of life, crucial for growth, development, and longevity. The depletion of these vital substances accelerates the aging process, leading to a loss of vitality and the early onset of age-related conditions.

Regular coffee consumption can lead to the rapid expenditure of yuan qi, resulting in chronic fatigue and diminished resilience against stress and illness. As jing depletes, the body’s ability to regenerate and repair itself diminishes, leading to signs of premature aging such as wrinkles, gray hair, and a decline in cognitive and physical abilities.

The Kidneys, which store jing, play a central role in maintaining youthful vigor. Overstimulation from coffee taxes the Kidneys, contributing to their gradual weakening. This weakening manifests in symptoms like lower back pain, weak bones, and diminished sexual vitality—hallmarks of aging in Chinese medicine.

Understanding the connection between coffee, loss of vitality, and aging emphasizes the need for mindful consumption and the adoption of practices that nurture and preserve yuan qi and jing. By reducing coffee intake and incorporating nourishing alternatives, individuals can support their long-term health and vitality, promoting graceful aging and enhanced quality of life.

Mind-Body Connection of Coffee

From the holistic viewpoint of Chinese medicine, the mind and body are interconnected, and the effects of coffee are not limited to the physical realm. The overstimulation caused by coffee can lead to mental restlessness and anxiety. This can disrupt the Shen, or spirit, which resides in the Heart and is responsible for mental clarity, emotional stability, and overall psychological well-being. When the Shen is disturbed, it can lead to symptoms such as anxiety, agitation, and sleep disturbances. Combined with symptoms of Stomach Fire, Liver Fire, and yin deficiency heat, it becomes clear how coffee can contribute to a state of overall imbalance and disharmony in both the mind and body, underscoring the importance of addressing not only the physical but also the mental and emotional impacts of coffee consumption.

The Five Elements of Coffee

The Five Elements theory is a fundamental framework for understanding the relationships and interactions within the mind, body, and the natural world. The Five Elements—Wood, Fire, Earth, Metal, and Water—correspond to various organs, emotions, and environmental factors. Understanding coffee through the Five Elements theory illustrates the mind-body connection of coffee:

  • Wood Element (Mù; 木): The Wood element, associated with the Liver and Gallbladder, is responsible for the smooth flow of qi and emotions. Coffee’s stimulating nature can over-activate the Wood element, leading to irritability, frustration, and tension. This mirrors the overstimulated state of our culture, where stress and impatience are prevalent.
  • Fire Element (Huǒ; 火): Coffee is associated with the Fire element due to its stimulating and heating properties. Fire governs the Heart and Small Intestine, and excessive Fire can lead to symptoms such as anxiety, insomnia, and palpitations. The consumption of coffee can exacerbate these conditions, reflecting an imbalance in the Fire element.
  • Earth Element (Tǔ; 土): The Earth element, linked to the Spleen and Stomach, governs digestion and nourishment. Coffee’s diuretic and drying effects can weaken the Earth element, leading to digestive issues, dampness, and a feeling of heaviness. This parallels the depletion of natural resources and the resulting imbalances in our environment and economy.
  • Metal Element (Jīn; 金): The Metal element, associated with the Lungs and Large Intestine, governs respiration and elimination. Excessive coffee consumption can disrupt the Metal element by overstimulating the nervous system, leading to shallow breathing and irregular bowel movements. This reflects the disconnection and instability seen in societal structures.
  • Water Element (Shuǐ; 水): The Water element, linked to the Kidneys and Bladder, is the foundation of vitality and essence (jing). Coffee’s impact on the Kidneys and the depletion of jing can weaken the Water element, leading to symptoms such as lower back pain, premature aging, and diminished resilience. This is akin to the depletion of natural resources and the unsustainable growth patterns in our society.
The Micro and Macro of Internal Fire

Identifying The Impacts of Coffee on Personal Health

For those curious about the impact of coffee on their own health, tongue diagnosis serves as a valuable tool. The tongue is considered a mirror of the body’s internal state, and changes in its appearance can indicate underlying imbalances.

Signs of Heat and Dampness on the Tongue

  • Heat: A red tongue body with a yellow coating suggests excessive internal Heat, which could be indicative of Liver Fire or Stomach Fire. Accompanying symptoms may include irritability, restlessness, and insomnia.
  • Dampness: A swollen tongue with teeth marks on the sides, a thick and greasy coating, or a pale, puffy appearance can indicate Dampness. Symptoms may include bloating, lethargy, and a feeling of heaviness.

General Indications and Signs of Heat and Dampness

  • Excess Heat: Individuals may experience symptoms such as red eyes, dry mouth, mouth ulcers, and a rapid pulse. These symptoms suggest that coffee may be exacerbating internal Heat conditions.
  • Yin Deficiency Heat: Signs include night sweats, a feeling of heat in the palms and soles, dry throat, and a red tongue with little or no coating. This indicates that coffee is depleting the body’s yin fluids.
  • Dampness: Common symptoms are a heavy sensation in the body, lethargy, loose stools, and a slippery pulse. These signs suggest that coffee is contributing to Dampness accumulation.

By observing these signs, individuals can gain insights into how coffee may be affecting their internal balance.

Coffee as a Reflection of Cultural Pathology

The consumption of coffee is not just a personal choice but a reflection of a broader cultural pattern. Our modern society is characterized by a state of constant stimulation, urgency, and excess. This mirrors the Chinese medicine concept of excess Heat, which we can observe not only in individual health but also in the environment, climate change, and the economy.

The Microcosm and Macrocosm of Cancer

Our culture’s obsession with coffee and stimulation can be seen as a microcosm of a larger pathology—one of excessive Heat and rampant growth, akin to cancer. Just as cancer cells grow uncontrollably, fueled by excess, our society’s relentless pursuit of productivity and stimulation mirrors this pathological growth. This unchecked expansion leads to resource depletion, environmental degradation, and economic instability, much like how coffee depletes yuan qi and jing, leading to a decline in health and vitality.

Yin Deficient Heat and Cancer

  • In Classical Chinese Medicine (CCM) and Traditional Chinese Medicine (TCM), yin deficient heat is a state where the body’s cooling and nourishing fluids are depleted, leading to unchecked yang (heating) energy. This imbalance creates an internal environment of excessive Heat and dryness, which can contribute to the development of cancer. Cancer, in this context, is seen as a manifestation of uncontrolled, pathological growth that mirrors the unchecked Heat and stimulation in our bodies.
  • Yin deficiency heat creates a conducive environment for cancer because the body’s natural cooling and moistening mechanisms are compromised. Without sufficient yin to balance the yang, cellular processes can become dysregulated, leading to the uncontrolled proliferation of cells. Symptoms of yin deficient heat, such as chronic inflammation, dryness, and heat sensations, reflect the body’s struggle to maintain balance and can contribute to the pathological conditions that foster cancer development.

Dampness and Cancer

  • Dampness, another critical factor in Chinese medicine, refers to the accumulation and stagnation of fluids within the body. This pathological condition obstructs the flow of qi and blood, creating a toxic environment that can contribute to cancer. Dampness can lead to the formation of phlegm, which is often associated with tumor development in both Classical Chinese Medicine and Traditional Chinese Medicine.
  • The presence of Dampness in the body creates a sluggish, heavy, and toxic internal environment. This stagnation can prevent the proper elimination of waste and toxins, leading to cellular damage and mutation. The accumulation of Dampness, combined with the Heat generated by yin deficiency, creates a breeding ground for cancerous growths, as the body’s natural detoxification and regulatory systems are overwhelmed.

Environmental Concerns and Climate Change

  • The excessive Heat generated by industrial activities, deforestation, and the burning of fossil fuels parallels the internal Heat generated by coffee consumption. Both contribute to a state of imbalance and disharmony. Climate change, with its rising temperatures and increasing natural disasters, is a macrocosmic reflection of the microcosmic excess Heat seen in personal health.
  • Just as the environment suffers from the relentless buildup of Heat, our bodies experience similar turmoil when overstimulated by coffee. The continuous strain on natural resources and the resultant ecological imbalance mirror the depletion of yin and the exacerbation of Heat within the body, highlighting the interconnectedness of personal health and environmental sustainability.

Economic Concerns and Living in a Post-Capitalism System

  • The relentless drive for growth and productivity in the global economy can be likened to the overstimulation caused by coffee. Just as coffee forces the body to expend its energy reserves, the economy’s focus on perpetual growth often leads to resource depletion, financial crises, and economic instability. This unsustainable approach ultimately results in systemic imbalances, much like the depletion of yuan qi and jing in the body.
  • The pursuit of constant economic expansion parallels the body’s overstimulation and subsequent exhaustion from excessive coffee consumption, reflecting broader issues of unsustainable practices and the need for a more balanced approach to both economic and personal health.

By recognizing these parallels, we can begin to understand the importance of balance and moderation both in our personal lives and in broader societal contexts. Addressing the root causes of excess Heat and overstimulation can lead to more sustainable and harmonious ways of living. Cultivating balance, moderation, and sustainability in our personal lives and societal structures is essential for long-term health and well-being.

Choose eco over ego

Final Thoughts from the Herbalist

As a popular beverage in many cultures, coffee has become a daily ritual for countless individuals. However, from a Classical Chinese Medicine (CCM) and Traditional Chinese Medicine (TCM) perspective, its consumption can have detrimental effects on the body’s balance. By introducing Heat and Dampness and depleting vital energy reserves such as yuan qi and jing, coffee can disrupt the harmonious flow of energy essential for health. Furthermore, coffee consumption reflects a broader cultural pathology of excess Heat and overstimulation, mirrored in environmental, economic, and personal health patterns.
