[[File:Kasa_Samprapti.JPG|500px|'''Image 1: Samprapti of Kasa'''|thumb]]

*[[Dosha]]: [[Vata]], [[Kapha]]
*[[Dushya]]: [[Rasa]]
*Srotasa: pranavaha, rasavaha

*In association [[kapha]] or [[pitta]], [[dosha]]-specific measures shall be used. [Cha.Sa.[[Chikitsa Sthana]] 18/132] When [[vata]] dominant kasa is associated with [[pitta]], medicated ghee and milk after food is indicated. [A.Hr.Chikitsa Sthana 3/2]<ref name= Hridaya > Vagbhata. Ashtanga Hridayam. Edited by Harishastri Paradkar Vaidya. 1st ed. Varanasi: Krishnadas Academy;2000.</ref>

===Disease-specific treatment principles===
 
'''Cough due to traumatic injury:'''
 
*This acute condition should be treated immediately with drugs promoting strength and improving muscle tissues ([[mamsa dhatu]]). Sweet and life-promoting (jivaniya) drugs shall be used.  [Cha.Sa.[[Chikitsa Sthana]] 18/134]  
*Kerria lacca (laksha) mixed with honey with milk is advised. [A.Hr.Chikitsa Sthana 3/73]<ref name=Hridaya/> 
*Medicines used for [[pitta]] dominant kasa are indicated.

[Cha.Sa.[[Chikitsa Sthana]] 18/150]  These therapies and purification therapies  (srotoshodana) shall be done alternatively. As all three [[dosha]]s are vitiated in this type of kasa, the therapies aim to pacify and balance all three [[dosha]]s. [Cha.Sa.[[Chikitsa Sthana]] 18/187-88]

If the amount of [[pitta]] and [[kapha]] are less, and associated with emaciation, then ghee processed with Pistacia chinensis (karkatakasringi), Sida cordifolia (bala), Sidarhombifolia (atibala) and milk should be given.
 
If kasa is associated with discoloration or difficulty in urination, then milk processed with Pueraria tuberose (vidari), Neolamarckia cadamba (kadamba) or with tender fruits of Flacourita jangomas (tall) should be given. [Cha.Sa.[[Chikitsa Sthana]] 18/153-54]

==Contemporary views==

===Case reports===

'''Solanum xanthocarpum'''

The whole plant (panchanga) of Solanum xanthocarpum showed significant anti-tussive activity when compared to its roots. Administration of 10 gms of powder of drug for 10 days in 30 patients reported better action over [[kapha]] dominant kasa. The drug might be suppressing the central cough center by stimulating opioid receptors in the brain. It may be acting through protective ciliary activity in the respiratory tract. The action as demulcent can relieve cough.<ref name=mansukh>Mansukh S Parmar (2012): A  comparative pharmacognostical, physicochemical and pharmacological study of moola and panchanga of Kantakari (Solanum xanthocarpum Schrad. & Wendl.) w.s.r. to its kasahara karma, Department of Dravyaguna Vigyan, IPGT&RA, Jamnagar</ref>

'''Tribulus terrestris'''

An experimental study reported anti-tussive activity of root powder of Tribulus terrestris (laghu gokshura) in sulphur dioxide induced cough models. The number of cough episodes was significantly less in  Tribulus terrestris (laghu gokshura) root administered group. While root of Pedalium murex (brihat gokshura) showed insignificant decrease in number of cough episodes. In a clinical study, administration of powder of Tribulus terrestris (laghu gokshura) root and root of Pedalium murex (brihat gokshura), 3gm twice a day in 28 patients of kasa is observed. It reported better effect in group administered with Tribulus terrestris. The effect was better in reducing [[vata]]kasa. This study also suggested effect of drug on central nervous system and its anti-inflammatory activity.<ref name=chandrika>Chandrika N Methekar (2012): A  comparative pharmacognostical and phyto pharmacological assessment of moola, panchanga of laghu gokshura (Tribulus terrestris Linn.) and Brihat gokshura (Pedalium murex Linn.) w.s.r to its kasahara karma, Department of Dravyaguna Vigyan, IPGT&RA, Jamanagar</ref> 

'''Combination of terminalia chebula and rock salt''' 

In a study conducted on 19 patients, Terminalia chebula (haritaki) with Rock salt (saindava lavana) was found effective in reducing the symptoms of [[kapha]]kasa. There was 92.3% relief in cough with sputum and itching in throat. The action of haritaki on [[vata]] and [[kapha]][[dosha]] due to its hot potency is observed as reason behind efficacy.<ref name=rout>Rout AK, Dwivedi RR.

PMID: 22736910; PMCID: PMC3326882.</ref> 

'''Kantakari-marichaleha'''

In a study, kantakari-marichaleha (ayurvedic formulation) was administered for 7 days in 30 children with symptoms of [[kapha]]kasa. It was found effective in reducing the signs and symptoms.<ref name=sawant>Sawant S, Nandgaonkar J A, Gujarathi R H.

'''Samasharkara powder formulation'''
 
In another study on 60 patients with [[kapha]]kasa, 10gms of Samasarkarachurna for 15 days is found effective in reducing the signs and symptoms.<ref name=dighe>Dighe P M. Efficacy of Samsharkara Churna in Kaphaj Kasa. Ijam. 2013, 4(1), 36-42</ref> 

'''Bhrigarajasava as adjunct to anti tubercular treatment'''
 
In another study conducted on 60 patients with pulmonary tuberculosis (TB), administration of Bhrigarajasava along with the standard treatment was found effective in reducing the cough. The cough progressively diminished and became occasional and non-productive within 15 days of treatment.<ref>Dornala SN, Dornala SS.

PMID: 23723670; PMCID: PMC3665204.</ref>

'''Vyaghri-haritaki avaleha in chronic bronchitis'''

A study on 66 patients with chronic bronchitis reported that Vyaghri-haritaki avaleha effectively reduced the productive cough, which is the cardinal feature of chronic bronchitis.<ref>Ram J, Baghel MS. Clinical efficacy of Vyaghriharitaki Avaleha in the management of chronic bronchitis. Ayu. 2015 Jan-Mar;36(1):50-5. doi: 10.4103/0974-8520.169009. PMID: 26730139; PMCID: PMC4687240.</ref>

'''Unctuous enema in pertussis'''
 
Administration of unctuous enema (sneha[[basti]]) in pertussis patients of pediatric age group ( n=2) was studied. It was found very effective in reducing dry cough. Sesame oil in a dose of 10 - 20ml is used in [[basti]] for 14 days along with antimicrobial therapy. Initially, the intensity of cough was reduced, followed by a reduction in the frequency of cough episodes. Unctuous enema acts directly over the colon to restore normal functions of [[vata]][[dosha]].<ref>Gujarathi RH, Gokhale VM, Tongaonkar JN. Effect of Basti (oil enema) therapy for the management of cough in pertussis. Ayu. 2013 Oct;34(4):397-400. doi: 10.4103/0974-8520.127722. PMID: 24696577; PMCID: PMC3968703.</ref>

'''Kasahara dashemani tablets'''

In 40 children with kasa, administration of Kasahara Dashemani vati for 60 days showed relief in all symptoms of kasa. Reduction in acute eosinophil count (AEC) and erythrocyte sedimentation rate (ESR) levels are noted. The decrease in IgE levels indicates the drug’s action against allergy. It is found effective in [[vata]] and [[pitta]] predominant kasa.<ref>Subrahmanya NK, Patel KS, Kori VK, Shrikrishna R.
