Anxiety, sadness, constant irritability, or that feeling that something inside just won’t resolve itself are not weaknesses or exaggerations. They are signals. And Traditional Chinese Medicine has been understanding them for thousands of years with a precision that Western science is now beginning to confirm.
In this article, we’ll tell you what TCM says about negative emotional states, what acupuncture can (and can’t) do for you, and why each emotion is treated differently depending on the organ it’s connected to.

The body and mind are not separate
In Traditional Chinese Medicine, emotions are not something that only happens in the head. They are manifestations that the body expresses when an organ is overloaded, blocked, or deficient. Every emotion prolonged over time ends up affecting its corresponding organ, and vice versa: a weak organ predisposes one to feel that emotion more intensely.
This principle is called the mind-body connection, and it is the basis of the entire emotional approach in TCM. That is why acupuncture does not treat sadness, anger, or fear as separate categories: it reads them in the body, identifies the pattern, and works on the meridians and points that this pattern affects.
The five emotions and their organ
In Traditional Chinese Medicine (TCM), five main negative emotions are described, each linked to an organ. It is common to recognize more than one in each person, with a predominant emotion that sets the pattern:
Anger and frustration → Liver
In Traditional Chinese Medicine (TCM), the Liver is responsible for ensuring the free flow of Qi and Blood (Xue) throughout the body. When this flow stagnates, frustration, irritability, accumulated anger, mood swings, and, in the body, muscle tension, flank pain, indigestion, and irregular or altered menstruation appear.
Worry and Rumination → Spleen
The Spleen governs thought and the ability to transform. When it is overloaded by excessive worry, mental fatigue, constant rumination, difficulty concentrating, low appetite or, conversely, a craving for sweets, and a physical sensation of heaviness and a bloated abdomen appear.
Sadness and apathy → Lung
The Lung distributes Qi throughout the body and governs the skin and breathing. When sadness becomes chronic, this organ weakens: discouragement appears, lack of motivation, a feeling of not having enough air, dull skin, and increased vulnerability to colds and allergies.
Fear and Insecurity → Kidney
The Kidney stores the essence (that which sustains deep vital energy) and is associated with fear. When the Kidney is weakened by excessive fear, exhaustion, or excessive work without rest, insecurity, lack of willpower, profound fatigue, lower back pain, and a general feeling of cold that doesn’t go away with a coat appear.
Anxiety and Insomnia → Heart (Shen)
The Heart houses the Shen, which is the spirit, consciousness, the capacity for sleep and tranquility. When the Shen is agitated, anxiety, insomnia, nighttime awakenings, palpitations, a racing mind, and difficulty enjoying everyday things appear.
What does the scientific evidence say?

Research on acupuncture and emotional health has grown a lot in the last five years. Today we have solid meta-analyses that support its use as a complementary tool.
In 2024, a review published in Frontiers in Neuroscience concluded that acupuncture is effective in reducing the symptoms of depression, especially in mild and moderate cases. That same year, another online review at CNS Spectrums confirmed these results by analyzing multiple variables and subtypes of depression.
A very interesting work published in 2025 in Frontiers in Psychiatry used neuroimaging to demonstrate that acupuncture modifies the activity of brain networks involved in emotional regulation. And a 2026 meta-analysis in World Journal of Psychiatry confirmed that acupuncture raises levels of serotonin (5-HT), one of the key neurotransmitters in mood.
What acupuncture can (and can’t)
It’s important to be honest about the limitations. Acupuncture can be a very valuable tool, but it’s not a magic bullet nor a substitute for other treatments in serious cases.
- Reduce general anxiety and the constant feeling of worry
- Improve sleep quality in cases of insomnia of emotional origin
- Calm irritability and frequent mood swings
- Ease deep sadness and apathy (in mild and moderate cases)
- Support during periods of grief, separation, or life crises
- Reduce the use of anxiolytic or antidepressant medication under medical supervision
- Prevent relapses in people prone to negative emotional states
- Improve energy levels and motivation when emotional exhaustion predominates
However, it is not sufficient (alone) in cases of:
- Severe major depression with suicidal ideation
- Severe psychiatric disorders (psychosis, bipolar disorder in the acute phase)
- Acute panic attacks or very severe anxiety attacks
- Severe addictions in the active use phase
In these cases, acupuncture works very well as a complement to medical or psychological treatment, not as a substitute. At Kan & Li, we always recommend maintaining professional support when necessary.
What to expect from a session on emotional issues?
At Kan & Li, each person is holistically assessed before beginning. We listen to your story, take your pulse, observe your tongue, and ask about sleep, appetite, digestion, predominant emotions, and more.
From there, we design a personalized protocol. In most cases, sessions are combined with recommendations for Chinese herbal medicine, breathing techniques, and lifestyle adjustments, because in TCM the emotional approach is always multidimensional.
The usual frequency is one session per week in the initial phase, spacing out thereafter depending on progress. Most people notice some positive change from the first or second session, and sustained improvement after 6-8 weeks.
Why choose Kan & Li?
- More than 10 years of experience in acupuncture and emotional support
- Personalized diagnosis based on each person’s specific pattern
- Combination of acupuncture, auriculotherapy, herbal medicine, and lifestyle recommendations
- Calm, confidential, and unhurried environment in the heart of the Eixample district
You don’t have to carry this burden alone
Negative emotional states are not a sentence or a character flaw. They are messages from the body and mind asking for rebalancing. And sometimes, that rebalancing is achieved by giving the body the tools it needs to return to its natural state.
Acupuncture is one of those tools. If you’ve been feeling anxious, sad, irritable, or just plain down for a while, Kan & Li can help you understand what’s going on and what path makes sense for you.
