Introduction

Kasa is one among Pranavaha Srotovikara (disorders of respiratory system) and Kaphaja Kasa (Chronic bronchitis) is a variety among Panchakasa (5 varieties of cough) wherein the morbid Kapha and Vatadosha (factor responsible for movement)[1] along with Rasa Dhatu Dushti involve in disease manifestation thus it explains the depletion in the level of nutrition in the patient suffering from this disease. The prevalence rate of Chronic Bronchitis is directly proportional to smoking and the excess usage of biomass fuels leading to low quality of air due to air pollution. In 2018, 9.0 million adults or 3.6% of those ages 18 or older had chronic bronchitis. There was an estimation that the Global prevalence of Chronic Bronchitis among people aged 30-79 years in 2019 was 10.3%, using the GOLD case definition which translates to 391.9 million people.[2]

More than 65 million people around the world have moderate to severe COPD as per 2021 study among which 35 million were observed to be cases of Chronic Bronchitis. In the past two decades, the Burden of Obstructive Lung Disease initiative and Global burden of Disease collaborators have pioneered efforts to collect country-specific population-based data on the prevalence of and risk factors for Chronic Bronchitis, providing updates on global estimates of deaths, prevalence and disability adjusted life years. In Charaka Samhita, it is mentioned that one should treat according to the severity of all types of Kasa, increases in successive order.[3]

Bronchodilators, Anticholinergic Agents, Beta Agonists, Glucocorticoids, Antibiotics, Oxygen therapy are the conventional treatments available and have modest results. The effect of these treatments last for few hours to maybe a day and if discontinued then there will be exacerbation.

A safe and cost-effective treatment which has to be oriented towards the Margavarana (obstructing channels) as well as Kaphaharana (removing phlegm) is the need of the hour. The formulation used in the present study contains potent drugs mentioned in Kasahara and Shawasahara Mahakashaya[4] in which the total efficacy of all the ingredients is been assessed. Thus, by keeping above aims this clinical trial is selected for the study.

Discussion

Pranavaha Srotas (Respiratory system) serves the functon of Shwasaprashwasa Kriya (act of inspiration and expiration) and during this act of respiration the air enters into the body.

This makes the Srotas to get exposed to environmental factors constantly. There builds up the Khavaigunyata (morbidity) and later gives rise to various Pranavaha Srotovikara (disorders of respiratory system).

Kaphaja Kasa is one such Pranavaha Srotovikara which is caused due to morbid Kapha and Vata Dosha.[8]

Shwasa Kasa Dashemani Ghana Kashaya contains Draksha (Vitis vinifera), Abhaya (Terminalia chebula), Amalaki (Emblica officinalis), Pippali (Piper longum), Shrungi (Pistachia chinensis), Kantakari (Solanum xanthocarpum), Punarnava (Boerhavia diffusa), Bhumyamalaki, Shati (Hedychium spicatum), Pushkaramoola (Inula racemose), Amlavetasa (Garcinia pedunculata), Ela (Elettaria cardamomum), Agaru (Aquillaria agallocha), Hingu (Ferula northex), Surasa (Ocimum sanctum), Jeevanti (Leptadenia reticulata), Duralabha (Fagonia cretica), Chanda.[9] Majority of the drugs possess Vatakapha Shamaka property which are two main Dosha involved in the disease. Some of the drugs such as Pippali[10], Kantakari[11], Surasa[12], Shati[13], Hingu[14], Ela[15], Chanda (Angelica archangelica, As the drug was not available, its substitute Angelica glauca was used)[16] have the properties of Deepana and Pachana thus, act at the level of Agni thereby reducing the Malarupi Kapha/ tenacious sputum. Pushkaramoola[17], Kantakari, Shrungi[18], Shati, Punarnava[19], Agaru[20], Pippali, Surasa, Duralabha[21] possess the properties of Chedana (breaking), Lekhana (scraping), Shothahara (anti-inflammatory). The Pratyatma Lakshana (cardinal feature) of Kaphaja Kasa (Chronic bronchitis) being Bahala, Madhura (sweetish), Snigdha (slimy), Ghana Kapha Nishtivana hence, the above mentioned properties help in Kapha Nissarana, Kapha Chedana, reduce Shotha and clears the obstruction. It is noted that in Kaphaja Kasa Vata is obstructed downwards and takes the Pratiloma Gati (in reverse direction) hence, Anulomana (downward movement) property of certain drugs like Abhaya, Hingu, Ela, Chanda and Amlavetasa helps to restore the normal Gati (movement) of Vatadosha. Drugs such as Amalaki, Jeevanti, Abhaya, Tamalaki, Draksha, Amlavetasa possess Rasayana (rejuvenating) and Brihmana (nourishing) properties which improves Rasadi Dhatu, Ojas/Bala further improving the subject’s quality of life.


As per Modern perspective, the drugs used to treat Chronic Bronchitis must have bronchodilator effect, antibiotic, anti-inflammatory and immune modulatory action. Draksha (Vitis vinifera) contains the constituents such as flavonoids, polyphenols, gallic acid, anthocyanins act as anti-oxidative, anti-inflammatory and anti-microbial. Abhaya (Terminalia chebula) contains high percentage of phenolics which are anti-oxidants. Studies have also showed that Ethanol and aqueous extract of Haritaki have anti-microbial and immuno modulatory effect. Amalaki provides antitussive effect due to its action on the mucus glands and thereby prevents hypersecretion in the airways. Pippali (Piper longum) contains volatile oil, alkaloids such as piperine and piper longuminine. Piperine, the prime constituent of Pippali has a significant anti-inflammatory action. Kantakari (Solanum xanthocarpum) contains apigenin which has anti allergic effect in addition. Also, the Glycoalkaloid and fatty acids of Solanum xanthocarpum acts as anti-histaminic. Punarnava (Boerhavia diffusa) contains coccineone, boeravinone, which possess the property of anti-inflammatory. Bhumyamalaki (Phyllantus niruri) contains ligans niranthin, phyltetralin, nirtetralin exhibit anti-inflammatory action to some extent. Rhizome of Shati (Hedychium spicatum) contains sitosterol, glucosides, diterpene-hedychenone and 7 hydroxy hedychenone and essential oils being the major constituents which are anti-inflammatory in nature. Duralabha (Fagonia cretica) contains Triterpinoides, saponins, oleonolic acid possess anti-inflammatory and antibacterial properties thus reducing infection. Tamalaki (Phyllantus niruri) contains phyllantin which shows immune modulatory action. Amlavetasa (Garcinia pedunculata) contains Garcinol, cambogin which are anti-inflammatory. Hingu (Ferula narthex) is a potent muscle relaxant which has an effect on tracheal smooth muscle due to muscarinic receptor blockage also causes broncho dilation. Ela (Elettaria cardamomum) contains flavonoids which have bronchodilator activity, antioxidant and spasmolytic activity. Pushkaramoola (Inula racemosa) contains Beta-sitosterol, Sesquiterpines lactones which are anti-inflammatory. The aqueous and alcoholic extract of Inula racemosa also shows anti histaminic property. Surasa (Tulasi) consists of flavonoids like triterpenoids and eugenol which show significant anti-inflammatory action.

Jeevanti (Leptadania reticulate) contains steroids, stigmasterol, sitosterol, triterpenoids have anti asthmatic property.

By the above discussion it is clear that, all the drugs mentioned in Shwasahara (relieving dysnoea) and Kasahara (relieving cough) Gana (group) have different properties such as anti-inflammatory, thereby reducing the airway inflammation and hypersecretion of mucus. Certain drugs such as Draksha, Pippali, Haritaki, Punarnava, Amalaki have immune modulatory, anti-oxidant activity which prevent the allergic responses. It can be said that on long term usage, these drugs potentiate immune system.

Conclusion

Shwasa Kasa Dashemani Ghana Kashaya was found to be effective in reducing the symptoms of Kaphaja Kasa/Chronic Bronchitis which was statistically significant with the p value <0.001. Among 40 subjects, all of them showed decrease in the SGRQ score by 22.3% which implies reduction in severity of symptoms, improvement in the quality of daily activities, 14 subjects showed improvement in PEFR value by 6.1% within 2 weeks of intervention of Shwasa Kasa Dashemani Ghana Kashaya. Majority of subjects had good overall improvement, 11 showed fair improvement, 2 showed moderate improvement and 1 patient with negative response. Even after 15 days of treatment, the medicine can be continued as there were no any adverse effects observed during the follow up period.
