In traditional Chinese medicine, the lungs are the „delicate canopy“ of the body - the most sensitive of the Zang organs. It governs Qi and breath, distributes defensive energy (Wei Qi) to the surface of the body and controls the water balance. If hot phlegm blocks the lungs, all these functions can no longer be carried out properly.

Phlegm-Heat in the Lung (Tan Re Zu Fei) is a fullness disorder: the phlegm is not cold and watery as with pure phlegm-dampness, but hot, viscous and yellowish. It sticks stubbornly in the lungs and is more difficult to clear. This combination of heat and mucus occurs in different ways: External wind-heat can enter the lungs and combine with moisture. Or a weak spleen produces moisture, which condenses into mucus - and is then „cooked“ by internal heat.

In TCM, the lungs have two main movements: Distributing (Xuan) upwards and outwards, and descending (Su Jiang) downwards. Hot phlegm blocks both directions. The Qi can no longer descend, resulting in coughing, wheezing and shortness of breath. It can no longer disperse - the Wei Qi does not reach the surface, the immune system is weakened.

The result of the mucus heat: The body fights against a stubborn blockage. The lungs cannot breathe freely, the viscous yellow mucus is stuck, the heat dries out the sensitive lung tissue. The chest feels tight and heavy, the cough is agonizing and productive.

The typical signs of mucus heat in the lungs:

• Cough with yellow, viscous mucus that is difficult to cough up
• Feeling of tightness and fullness in the chest
• Shortness of breath and wheezing
• Fever or feeling hot, especially in the afternoon
• Thirst with a craving for cool drinks
• Foul-smelling breath
• Dark, concentrated urine
• Constipation due to internal heat

The good news: Mucus heat in the lungs can be treated well with the right methods. Cooling, expectorant food, targeted acupressure, breathing exercises and proven TCM herbs can clear the heat, dissolve the phlegm and free your lungs again.

From a Western perspective, phlegm-heat in the lungs corresponds to a condition with inflammation and increased phlegm production in the airways. The body reacts to infections or chronic stimuli with an inflammatory reaction that produces thick, purulent phlegm - the yellow or greenish phlegm that TCM describes as „hot phlegm“.

Think of your airways as a fine tube system: Normally, they are lined with a thin layer of mucus that traps foreign bodies and germs and transports them to the outside. In the event of inflammation, the mucous membrane swells, produces thick, sticky mucus and constricts the airways. The result: difficult breathing, an agonizing cough and the feeling of not getting enough air.

Bacterial bronchitis, pneumonia, chronic obstructive pulmonary disease (COPD) or bronchiectasis are particularly common causes. Allergic asthma can also develop into this picture with secondary infection.

What does modern medicine show?

• Acute bronchitis: inflammation of the bronchial tubes with a productive cough and yellow sputum
• Pneumonia: pneumonia with fever, purulent mucus and shortness of breath
• COPD with exacerbation: exacerbation of chronic lung disease with increased, purulent mucus
• Sinusitis with postnasal drip: sinusitis with mucus flowing into the throat
• Bronchiectasis: Dilated bronchi with chronic mucus production
• Chronic smoker's cough: airways damaged by tobacco smoke with inflammation

Modern research confirms: The TCM diagnosis of „phlegm-heat in the lungs“ correlates with elevated inflammatory markers (CRP, leukocytes), purulent sputum and radiological signs of bronchitis or pneumonia. Studies have shown that TCM herbs such as Huang Qin (Baikal Gillwort) have antibacterial and anti-inflammatory effects on the respiratory tract.

This is exactly where TCM treatment comes in: It clears the heat (combats inflammation), dissolves the thick mucus, strengthens the lungs and the spleen as the root of mucus formation - holistically, sustainably and with methods that have been tried and tested for thousands of years.

Why BS+ for mucus heat in the lungs?

According to TCM: „The spleen is the source of phlegm, the lungs are the storehouse of phlegm.“ In the case of phlegm-heat, internal heat also combines with the phlegm - it becomes viscous, yellow and difficult to dissolve. The root cause is often a weakened spleen that does not transform moisture properly. An intestine with impoverished intestinal flora further weakens spleen function and encourages the formation of moisture, which condenses into stubborn mucus when exposed to heat. Only when the intestine is healthy can the spleen fulfill its task again and stop the formation of mucus at the root.

BS+ delivers 11 prebiotic fibers and thus specifically supports the development of a diverse intestinal flora. A strong intestinal flora strengthens the transformative power of the spleen, reduces the formation of cloudy moisture and removes the breeding ground for mucus heat. At the same time, a healthy gut supports the immune system - this is particularly important as mucus heat in the lungs is often associated with recurring infections.

Particularly important for mucus heat in the lungs:

• Strengthens the spleen function via healthy intestinal flora - so that less moisture is produced, which can condense into hot mucus
• Supports the immune system and helps the body to clear the heat component and reduce susceptibility to infection
• Promotes efficient digestion so that cooling, expectorant foods such as radish, pear and mung beans can develop their full effect

Acupressure is acupuncture without needles. - you can apply them yourself at any time. By applying targeted pressure to specific points, you activate the energy flow in the meridians and help your lungs to clear heat and dissolve phlegm.

These three points form an effective combination for clearing heat and dissolving mucus in the lungs. Lu 10 clears the lung heat directly, Di 04 strengthens the immune system and Ma 36 strengthens the spleen - so that the root of the mucus formation is eliminated.

Qi Gong opens the chest - Gentle, flowing exercises that strengthen your lung function and support the spleen so that no new mucus is produced. When there is mucus heat in the lungs, these exercises help to expand the chest cavity, clear the airways and promote deep breathing.

Regular practice of Qi Gong (as little as 10-15 minutes a day) has been shown to have positive effects on lung function, mucus reduction and general well-being.

These Qi Gong exercises are specially selected to dissolve mucus heat in the lungs. They open up the chest cavity, strengthen lung function and support the spleen so that no new mucus is produced.

The best time to exercise is between 3 and 5 a.m. - this is the lung time in the organ clock. Practical and equally effective for strengthening the spleen is the morning between 7 and 9 a.m. (stomach time).

Meridian Yoga combines yoga with traditional Chinese medicine. The result is a holistic exercise concept for better health and more energy.

The following exercises specifically activate the lung meridian - because the lung governs Qi and breathing. If there is phlegm heat in the lungs, activating this meridian helps to loosen the phlegm and restore free breathing.

Both exercises activate the lung meridian, which runs along the inside of the arm and is connected to the lungs. The lung governs Qi and breathing - by activating this meridian, you support both phlegm clearance and free breathing.

Particularly effective: Hold each position for 3-5 breaths, visualizing fresh, clear energy flowing into your lungs with each inhale and expelling phlegm and heat with each exhale.

„Let food be your medicine.“ - This principle has been valid in TCM for thousands of years. In the case of phlegm-heat in the lungs, the right diet is crucial to dissolve the hot phlegm and clear the heat.

The lungs belong to the element Metal, mucus is often caused by a weakened immune system. Earth (spleen). The diet should Cooling, light and expectorant be - anything that generates moisture or heat must be avoided.

What you eat, HOW you eat and WHEN you eat - all of this affects your phlegm, your lungs and your energy.

Start with ONE step!
Don't change everything at once.

Our suggestion for getting started:

1. Consistently avoid dairy products - 2 weeks
2. Eat radish or cooked pear daily - 2 weeks
3. Reduce fried foods, sweets and alcohol - 2 weeks

Step by step, you will notice how the mucus loosens, the heat subsides and you can breathe more freely again.

Your lungs will thank you!

Breathing is the bridge between body and mind. In TCM, we say: „The lungs govern qi“ — through conscious breathing, you can directly influence your energy flow, harmonize all organ systems, and activate your self-healing powers.

Studies show: Proper breathing activates the parasympathetic nervous system (rest & regeneration), massages the internal organs from within, improves oxygen supply, and reduces stress hormones. The good news: Just 5–10 minutes a day can have a measurable effect on your overall well-being.

When your body is relaxed, all organ systems can function optimally. Chronic tension blocks your body's self-healing powers and keeps you in a state of constant stress. Through targeted relaxation techniques, you activate the parasympathetic nervous system and send your body the signal: „Now I can regenerate, heal, and build strength.“

Progressive muscle relaxation is one of the most researched relaxation methods and has been used successfully for over 100 years. It helps you to recognize tension, actively release it, and achieve a state of deep relaxation—whenever you want.

Meditation calms the mind — and a calm mind harmonizes the body. In TCM, we know that every emotion affects a specific organ. Through regular meditation, you learn to break out of destructive thought patterns, find emotional balance, and strengthen your inner core.

Modern studies confirm: Meditation has been proven to change brain structure, reduce stress hormones, strengthen the immune system, and improve self-healing powers. Just 10 minutes a day can change your life forever.

In addition to traditional TCM treatment methods there are many everyday habits that help to dissolve mucus and heat in the lungs. The lungs love purity and fresh air - with the right habits you can support their healing.

Conscious deep breathing

Deep breathing opens the lungs and releases stagnation:

• Breathe in deeply and slowly 3-5 times a day for 5 minutes
• Breathe in through your nose, breathe out through your slightly open mouth
• Consciously breathe longer when exhaling than when inhaling
• Best practiced at an open window or outside

Abdominal breathing

Strengthens the diaphragm and improves lung ventilation:

• Place your hand on your stomach and feel how your stomach rises and falls
• Gently arch your stomach outwards as you inhale
• Gently pull your stomach inwards as you exhale
• Practice daily for 5-10 minutes - preferably in the morning and evening

Out into the fresh air

The lungs need fresh, clean air:

• Daily walks in the fresh air
• Open windows, ventilate rooms regularly
• Ventilate in the morning and evening in particular
• Forest walks are particularly beneficial for the lungs

Steam inhalation

Dissolves mucus and clears the airways:

• Inhale 1-2 times a day with thyme, eucalyptus or camomile
• Hot water in a bowl, towel over your head, inhale for 5-10 minutes
• Not too hot - choose a comfortable temperature
• Stay warm after inhaling and do not go outside immediately

Hot meals

The spleen loves warmth - and a strong spleen does not produce mucus:

• Prefer cooked food, avoid raw food
• Also eat breakfast warm (porridge, congee, soup)
• Avoid cold drinks - they weaken the spleen
• Soups and stews are ideal for eliminating mucus

Consistently avoid dairy products

Milk is the No. 1 mucilage-forming agent in TCM:

• Consistently avoid milk, cheese, yogurt, cream and quark
• Use plant-based alternatives such as oat milk or rice milk
• Also watch out for hidden dairy products in ready meals
• Noticeably less mucus after just 1-2 weeks

Eat regularly

The spleen likes rhythm and regularity:

• 3 meals at fixed times
• Biggest meal at lunchtime, eat light and early in the evening
• Don't eat too late in the evening - the spleen needs rest at night
• Reduce snacks between meals

Avoid brooding

Worry and brooding weaken the spleen:

• Excessive thinking depletes the spleen energy
• Don't work or watch the news while eating
• Breaking through spirals of worry - through exercise or distraction
• Meditation and mindfulness help to calm the mind

No alcohol

Alcohol generates damp heat in the body:

• Consistently avoid alcohol in any form
• Beer and wine in particular generate moisture and heat
• Even small amounts increase the mucus heat
• Instead, drink cool teas such as chrysanthemum or peppermint tea

No smoking

Smoking directly damages the lungs:

• Smoking is the biggest burden on the lungs
• E-cigarettes and shisha also pollute the airways
• Avoid passive smoking - even indoors
• After quitting, the lungs regenerate step by step

No hot spices in excess

Spicy food intensifies the inner heat:

• Chili, pepper, curry - increase the heat in the lungs
• Garlic and onions only in small quantities
• Prefer mild spices such as turmeric or cardamom
• Ginger only in small quantities - it is also warming

No fried food

Deep-frying generates heat and moisture:

• Consistently avoid chips, potato chips and fried snacks
• Also avoid breaded dishes and fast food
• Instead, steam, boil or lightly fry
• Reduce fatty meat - it produces moisture and mucus

Reduce stress

Emotional stress generates inner heat:

• Constant stress and anger create liver fire that attacks the lungs
• Plan regular relaxation - Qi Gong, meditation, walks
• Resolving conflicts instead of swallowing them
• Sufficient sleep - at least 7-8 hours

Air humidity

The right humidity protects the airways:

• 40-60% Humidity is optimal for the respiratory tract
• Use a humidifier for dry heating air
• Laying wet cloths over the heating as a simple solution
• Avoid excessive humidity - promotes mold growth

Keep dust free

Clean air relieves the lungs:

• Regular damp mopping instead of dry sweeping
• Use air purifier with HEPA filter if required
• Wash bed linen regularly at 60°C
• Clean carpets and curtains regularly

Avoid allergens

Allergens irritate the airways and increase mucus:

• Avoid pollen, mold and animal hair as much as possible
• Keep windows closed when pollen is flying
• Wash hair and change clothes after spending time outdoors
• Use mattress and pillow covers for allergy sufferers

Do not smoke and avoid passive smoking

Smoke is poison for the lungs:

• Creating a smoke-free environment - at home and at work
• Ventilate rooms thoroughly after contact with smoke
• Change smoking clothes immediately
• Incense sticks and candle smoke also pollute the lungs

The dissolution of mucus heat in the lungs requires consistency and patience. The most important step is to change your diet - avoid mucus-forming foods and prefer cool, light food. At the same time, breathing exercises and fresh air help to actively cleanse the lungs. Pay attention to your body's signals: if the mucus becomes less and your breathing freer, you are on the right track.

When to see a doctor? If you have a high fever of over 39°C, purulent phlegm, blood in the sputum, severe shortness of breath or symptoms that last longer than 3 weeks, you should definitely consult a doctor. TCM and Western medicine complement each other perfectly here - medical clarification is particularly important for severe or persistent cases.

TCM is not a quick fix for symptoms., but rather a holistic healing process. You will achieve the best results if you consistently integrate the treatment into your daily routine and give your body time to regenerate.

Start with ONE step

Don't try to change everything at once! That's overwhelming and leads to
usually leads to you giving up. Instead:

• Week 1-2: Consistently avoid dairy products, fried foods and mucus-forming foods
• Week 3-4: Acupressure Lu 10 and Tue 04 daily
• Week 5-6: Qi Gong „Drawing the bow“ daily 10 min.
• Week 7-8: Supplement TCM herbal mixture
• From week 9: Add further methods as required

Realistic expectations

After 2–3 weeks: First improvements noticeable

• Less viscous mucus
• Breathe easier
• Less feeling of heat in the chest

After 6–8 weeks: Significant improvements

• Significantly less phlegm and coughing
• Freer breathing and more stamina
• Heat signs are decreasing

After 3–6 months: Sustainable healing

• Lungs feel free and clear
• Mucus and heat are permanently dissolved
• Immune system is strengthened and more resistant

TCM vs. Western medicine

TCM and Western medicine are not mutually exclusive—they complement each other!

When Western medicine is important:

• In acute emergencies
• In case of structural damage
• In case of infections
• For accurate diagnoses (laboratory, imaging)

Where TCM has its strengths:

• In case of functional disorders
• For chronic complaints
• For prevention
• For holistic healing

Ideal: Combine both systems! Use Western medicine for
Acute treatment and accurate diagnosis, TCM for lasting healing
and strengthening the body's self-healing powers.

Important: Never stop taking prescribed medication without consulting your doctor first!
Talk to your doctor when you start TCM treatment.
