Respiratory Cough
Classical Nomenclature: Kasa-Pratishyaya (कास-प्रतिश्याय)
Respiratory cough in Ayurveda is understood mainly as Kasa (cough) often linked with Pratishyaya (nasal congestion and rhinitis). It is typically a Kapha-Vata condition of the Pranavaha srotas, presenting as dry or productive cough with blocked or runny nose, throat irritation and chest heaviness.

•1. Clinical Overview & Definition
Respiratory cough is one of the most common upper-airway complaints. In Ayurveda it is described as Kasa — a forceful expulsion of air through the mouth that produces a characteristic sound — and it frequently appears together with Pratishyaya, the classical presentation of nasal congestion, sneezing and discharge. Together they correspond closely to cough with cold, rhinitis and respiratory congestion in modern terms.
Classical texts treat Kasa both as a symptom of other diseases and as an independent condition with its own causes and pathogenesis. Charaka Samhita dedicates Chikitsa Sthana chapter 18 to Kasa, while Pratishyaya is discussed in detail in Sushruta Samhita (Uttara Tantra) and Ashtanga Hridaya. The usual pattern is aggravation of Kapha with disturbed Vata (especially Prana and Udana Vayu) in the channels of breath, often after cold exposure, heavy or incompatible food, dust, smoke or seasonal change.
Ayurvedic care emphasises removing the cause (nidana parivarjana), supporting digestion so that Ama does not keep feeding mucus, clearing the nasal and chest channels, and soothing the throat. Warm, light food, steam, rest and simple kitchen herbs are the first supports. Persistent cough, breathlessness, high fever, chest pain or blood in sputum need prompt medical assessment and are not managed with home care alone.
2. Ayurvedic Perspective (Samprapti & Nidana)
Disease Pathogenesis (Samprapti)
Causative factors aggravate Kapha and disturb Vata, especially Prana and Udana Vayu. Impaired Agni allows Ama to form and mix with Kapha, producing sticky mucus. This obstructs Pranavaha srotas (the channels of breath) and the nasal passages (Ghrana moola). Vata, blocked in its normal downward and outward movement, is forced upward through the chest, throat and head and expelled through the mouth as cough (Kasa). In the nose the same obstruction appears as Pratishyaya — sneezing, blockage and discharge. If Kapha predominates the cough is productive and heavy; if Vata predominates it is dry, spasmodic and worse in cold, dry air; if Pitta joins there may be burning in the throat and yellowish sputum.
Classical Root Causes (Nidana)
- Exposure to cold wind, sudden weather change, air-conditioning or damp weather
- Dust, smoke, pollen, pollution and other inhaled irritants
- Cold, heavy, oily, sweet or incompatible foods (Viruddha Ahara), including excess curd, ice cream and refrigerated drinks
- Suppression of natural urges such as sneezing, coughing, thirst or sleep (Vega dharana)
- Daytime sleep, late nights, inadequate rest and irregular daily routine
- Weak digestive fire (Mandagni) leading to Ama, which feeds excess Kapha in the respiratory tract

4. Primary Etiological Causes (Hetu)
01.Seasonal colds, viral upper-respiratory infections and lingering post-viral cough
02.Allergic rhinitis, sinus congestion and post-nasal drip irritating the throat
03.Exposure to cold air, dust, smoke, pollution or occupational irritants
04.Kapha-aggravating diet and weak digestion, which increase mucus in the airways
05.Irregular sleep, daytime napping and suppression of sneezing or coughing
06.In some people, reflux, chronic sinusitis or an unresolved Pratishyaya that progresses into Kasa
5. Diet & Lifestyle Protocols (Pathya & Apathya)
In Ayurveda, diet (Ahara) is considered medicine itself: "Without proper diet, medicine is of no use. With proper diet, medicine is of no need."
Wholesome & Recommended (Pathya)
- ✓Warm water through the day; ginger, tulsi or cinnamon infusions taken warm
- ✓Light, freshly cooked food such as moong dal soup, rice gruel, khichdi and vegetable soups
- ✓Spices that kindle Agni and help clear Kapha: dry ginger, black pepper, turmeric, garlic and a pinch of long pepper, as tolerated
- ✓Honey in small amounts once food or tea has cooled (never heated honey); traditionally used as anupana for cough
- ✓Old rice, barley, horse gram and other light grains classically listed as pathya in Kasa
- ✓Warm salt-water gargles and steam inhalation to ease throat irritation and nasal blockage
Strictly Avoid (Apathya)
- ✕Cold drinks, ice, ice cream, refrigerated leftovers and iced desserts
- ✕Curd, excess milk, banana, fried snacks and other heavy, Kapha-increasing foods
- ✕Oily, stale, excessively sweet or incompatible food combinations (Viruddha Ahara)
- ✕Daytime sleep, late nights and sleeping in a damp or cold room
- ✕Direct cold wind, air-conditioning on the face and chest, and dusty or smoky environments
- ✕Suppressing sneezing, coughing, thirst or the urge to clear the throat
Therapeutic Yoga, Pranayama & Lifestyle
Daily Habits (Vihara)
- •Keep the neck, chest and feet warm; cover the nose in cold wind or pollution.
- •Inhale steam once or twice a day from hot water, optionally with ajwain or tulsi, taking care not to scald.
- •Sleep with the head slightly raised if night congestion or post-nasal drip disturbs rest.
- •Rest the voice; avoid shouting, cold baths and strenuous exercise until the cough eases.
- •Eat only when hungry, keep meals warm and light, and stop eating before fullness to protect Agni.
- •If using nasal oil (pratimarsha nasya) such as a drop of warm Anu Taila, do so only as advised by a qualified practitioner.
Yoga Asanas & Breathwork
- •Anulom Vilom (alternate-nostril breathing) for 5–10 minutes once the nose is reasonably clear
- •Bhramari (humming-bee breath) to soothe the throat and calm Vata
- •Gentle Ujjayi breathing if it does not provoke coughing
- •Bhujangasana (cobra) and Matsyasana (fish) to open the chest once acute fever has settled
- •Avoid forceful Kapalabhati or Bhastrika during an acute productive cough, fever or breathlessness

- Seek urgent medical help for breathlessness, high fever, chest pain, confusion, or blood in sputum.
- Do not give honey to infants under one year of age.
- People with asthma, COPD, heart disease, diabetes, pregnancy, or those taking medicines should consult a qualified clinician before using concentrated herbs or classical formulations.

8. Frequently Asked Questions
Cough is called Kasa. When it comes with a blocked or runny nose, sneezing and head heaviness, it is often linked with Pratishyaya (rhinitis or cold). The combined picture is Kasa-Pratishyaya, which maps closely to respiratory cough and congestion.
