Owing to its incorporeal nature and instability [[vata]] is ''anasadhya'' (inaccessible) also. The inaccessibility is characterized in regard to its functional and physical attributes but more relevant regarding the therapeutic aspect. Above explained cardinal features make [[vata]] achintya veerya (inconceivable prowess) and [[dosha]]nam neta (propeller of all functional elements in the body).[Cha. Sa. [[Sutra Sthana]] 1/8]

=== Properties of ''vata'' ===

=== Properties of [[vata]] ===

In [[Vatakalakaliya Adhyaya]], questions have been raised about exciting and alleviating factors regarding qualities of ''vata''. ''Ruksha''(dry), ''laghu''(light), ''sheeta''(cool), ''daruna'' (dreadful), ''khara'' (rough) and ''vishada'' (clean) have been explained as qualities of ''vata''. Repeated use of substances with these qualities and actions of such similar qualities causes aggravation and excitation of ''vata'' and is alleviated by use of substances possessing contrary qualities. This brings out the phenomenon of two mutually interrelated and inseparable of ''sharira vayu'' viz.

#that, the sharira [[vayu]] is a biophysical force and  

#that it is closely associated with material substances which form part of the structure of the body for example, functions of nervous system. It is a chemical reaction sequence which occurs during the course of life. This chemical reaction –sequence, can be accelerated (excited) or inhibited by substances with similar properties (''dravya samanya''), qualities (''guna samanya'') and actions (''karma samanya'') and inhibited by substances with opposite properties. In other words, it may be concluded that the bio – physical force – the ''sharira vayu'' – is closely linked with some material structural factors. These can be influenced by diet and medicine on the basis of similar increase and opposite decrease.

==== Types of ''vata dosha'' ====

==== Types of [[vata]] [[dosha]] ====

 

In Vedic literature, as a medical system, the important five types of [[vata]] are explained with their locations and functions. The word ''tantrayate'' is used to explain the functional quality of [[vata]] and ''sharira'' (physical body) is ''yantra'' for functioning of ''tantra''. The [[vata]] [[dosha]] on basis of its functions is classified into five types. They reside in the ''sharira'' at the level of ''sharira parmanu'' (cell) and also at gross level. Five types of [[vata]] work together in a synchronized manner for the normal functioning of the sharira ([[vayu]] tantrayantra dhara). (verse 5-11)

#which cause indirect ''vata'' vitiation.  

#which cause indirect [[vata]] vitiation.  

Day sleep (''divaswapna'') do not directly lead to vitiation of ''vata''. However, it leads to formation of ''ama'' and cause ''vata'' vitiation indirectly by obstructing ''vata''. ''Vegasandharana'' (suppression of natural urges) and ''marmabhighata'' (trauma to vital organs) etc. are examples of direct vitiation. The pathogenesis is also bi-fold. The initial pathology is aggravation of ''vata'' and diminution of ''dhatus'' and vice versa. One augments the other. This ultimately causes emptiness in channels and rarity in tissues which gives more space for movements of ''vata''. The second pathology is by increase in ''dhatus'' leading to excessive filling in channels to cause their clogging and blocking ''vata''. (verse 15-19)

The clinical presentations vary according to the specificity of ''hetu'' (cause) and ''sthana'' (location). The treatment options also vary accordingly. For example if ''vata prakopa'' takes place due to ''ruksha vriddhi'' in ''pakvashaya'' it may lead to habitual constipation in which ''snigdha, ushna'' and ''tikshna aushadha'' like ''mishraka sneha'' may be a good treatment option.

If the same ''vata'' gets vitiated in ''amashaya'' due to ''snigdha vriddhi'', it leads to gastro-esophageal reflux disease (GERD), ''ruksha ushna'' and ''tikshna'' like ''gomutra bhavita shaddharana'' is the ideal treatment option. ''Anuvasana'' is the ideal therapy in ''vata'' vitiated in ''pakwashaya'', whereas ''vamana'' is the best therapy in ''vata'' vitiated in ''amashaya''. (verse 20-24)

The three characteristics of ''vata'' vitiation viz. ''svatantra dushti'' (vitiation due to independent specific causes), ''gata vata'' (increased movement of ''vata'') and ''avarana'' (obstruction to movement of ''vata''). imply three possible modes of pathogenesis in ''vata'' diseases. These can be further analyzed as follows; due to the following three important properties of ''vata'', it is regarded entirely different from other ''dosha''[Cha. Sa. [[Sutra Sthana]] 12/3]

=== Pathogenesis of various conditions ===

All the verses explain a specific type of ''samprapti'' (pathogenesis) like ''koshthagata vata'' (''vata'' affecting alimentary tract), ''amashayagata vata'' (''vata'' affecting stomach.) etc. They are not to be considered as a single disease. These specific diseases may lead to many disease presentations in which the treatment strategies can be generalized. Any ''dosha'' may occupy any particular site or area and lead to diseases. This type of pathology of vitiated ''vata'' is called as ''gatavata''.  Normally in all ''gatavata'', the affected ''dushya''(vitiated body components) will be ''kshina'' (depleted) and affected ''srotas'' will be ''rikta'' (empty). The concept of ''gatavata'' can be further explored physiologically. ''Dhatu'' are classified into two types’ ''asthayi'' (temporary) ''dhatu'' and ''sthayi'' (permanent) ''dhatu''. ''Asthayi dhatu'' are the ones which are ''dravaswarupa'' (liquid state) and undergoing conversion (''parinam apadyamananam'') and they are being ''vikshepita'' (circulated) from their ''mulasthana'' (origin) throughout the ''sharira'' (''abhivahana'') for the purpose of ''poshana'' (nourishment) of the ''sthayi dhatu''. This ''parinamana'' (conversion) and ''abhivahana prakriya''(transportation) takes place in ''marga'' (channel) which are known as ''srotas''; hence ''marga'' is one of the synonym used for ''srotas'' along with ''sira'' (vein), ''dhamani'' (artery), ''rasayani'' (capillary), ''rasavahini'' (channels carrying nutrient fluid), ''nadi'' (nerve), ''panthana'' (pathway), ''sharira chhidra'' (perforated channel), ''samvrita-asamvritani'' (covered or uncovered), ''sthana'' (site), ''ashaya'' (organ), ''niketa'' (habitat), ''shariradhatu avakasha'' (hollow space in body tissues).

''Prakupita''(vitiated) ''dosha'' have the capacity to further vitiate both ''sthanastha dhatu'' (fixed tissue element) as well as ''margagata'' (circulating tissue elements) ''sharira dhatu''. When ''prakupita vata'' vitiates the ''dhatu'', it is called as ''gatavata''. In this condition, vitiated ''vata'' affects the specific site due to specific etiological factors. While designing treatment protocol, in this context specific etiological factors for each and every ''gatavata'' related diseases must be observed to clarify why vitiated ''vata'' goes to specific part of the body or to specific ''dhatu'' to develop ''kosthagata vata, raktagata vāta'' etc. In this condition, ''dhatu'' is ''dushya'' (getting vitiated).

''Gudagata vata:'' It can also be explained that ''gudagata vata'' and ''pakvashayagata vata'' are different clinical entities. In ''gudagata vata'', obstruction of stool, urine and flatus is observed, whereas in ''pakvashayagata vata'' there is painful defecation, micturition with ''antrakujana'' (gurgling sound), ''atopa'' (distension) and ''anaha'' (constipation). ''Ashma sarkara'' (urolith) is exclusively present in ''gudagata vata'' with pain and atrophy in calf muscles, thighs, sacram, feet and back. This can be compared with lumbo-sacral plexopathy. It may be understood as in case of ''pakvashaya gatavata'', proximal part of large intestine along with ascending, transverse and descending colon is involved; whereas in ''gudagata vata'', involvement of sigmoid colon, rectum, anus and their nerve supply.

'''Amashayagata vata''': This is a typical presentation of ''vata'' leaving its own site and vitiating other site. Here the local ''dosha'' is considered important because it is more virulent than the external ''dosha'' coming from other sites. The clinical entities originating from ''amashaya'' (stomach) are caused due to vitiated ''vata'' entering into ''amashaya''. It increases emptiness of stomach leading to indigestion or ''ama pradoshaja vikara'' like ''visuchika'' (diarrhea) etc.

''Indriyagata vata'': ''Indriyagata vata'' is applicable to any sense organ. ''Indriya vadha'' may be interpreted as complete, partial or minimal loss of sensation. ''Shrotra''(ears) has specific importance among other ''indriya'', in which inherent ''dosha'' of ''shrotra'' is ''vata'' itself. So ''vata prakopa'' in ''shrotra'' is more impacting. It is worthy to remember the notion in ''vatakalakaleeya'' that ''vata'' is ''sarvendriyanam udyojaka'' (motivating factors for all sense organs).

Diagnosis of ''dhatukshaya'' (degenerative pathology) and ''avarana'' (obstructive pathology) induced vitiation of ''vata'': ''Vata'' can be vitiated due to ''dhatukshaya'' and ''margavarana'' types of pathogenesis. ''Dhatukshaya'' leads to depletion of tissues and more space for ''vata'' to move. This leads to ''gatavata'' phenomenon. ''Avarana'' of ''vata'' can be caused by other ''dosha'' or ''dhatu''. So the differences between ''avarana'' and ''gatavata'' should be understood.

So the differences between ''avarana'' and gata[[vata]] should be understood.

The word, ''avarana'' means obstruction or resistance or friction to the normal ''gati'' of ''vata''. Hence when its normal movement is hampered or vitiated, it becomes ''avrita'' and leads to different disorders. The ''gatatva'' and ''avritatva'' are entirely different phenomenon. Here an attempt is being made to differentiate the both physio-pathologies. [16]

#In ''avarana'', generally the vitiation of ''vata'' is passive. When vitiated ''dosha'' or any other thing obstructs the pathway of ''vata, avarana'' happens. Normal state of ''vata'' gets vitiated as ''avarana'' progresses. The substance which obstructs the pathway of ''vata'' is called as ''avaraka'' and the ''dosha'' (''vata'' in general or its components) affected by ''avarana'' is called as ''avariya'' or ''avrita''. Normally the ''avarana'' is caused by the etiological factors for the vitiation of ''avaraka''. Etiological factors for the vitiation of ''vata'' (''sva nidana'') will be absent. In case of ''gatavata'' the vitiation of ''vata'' will be active. Here its own etiological factors are operating in the vitiation of ''vata'' in the pathogenesis and the vitiated ''vata'' adopts specific pathway and abnormally localizes at particular sites.

#In the process of ''avarana chala'' property of ''vata'' is diminished due to obstruction. Other properties are not involved in the process of obstruction. But in case of ''gatatva'' the vitiation of ''vata'' takes place by involvement of other properties like ''ruksha, laghu, khara, vishada'' etc along with ''chala''.

#In ''avarana'' the ''gati'' of ''vata'' is obstructed partially or fully. Once gets obstructed the ''vata'' may simply get lodged there (''baddha marga, margarodha''), try to nullify the obstruction, may get covered by the obstructing substance (''avrita''), adopt an opposite direction (''pratiloma'') or alter the direction (''viloma''). The different terminologies have been used to denote ''avarana'' in different contexts according to the nature of ''avarana'' and the state of ''vata'' and ''marga'' (passage).

In case of ''gatatva'' the ''gati'' of vitiated [[vata]] aggravated and starts moving abnormally leading to localization at particular sites.''Avarana'' is caused by ''purnata'' (filling) of other [[dosha]] in the ''srotas/marga'' (passage) of [[vata]]. In ''gatatva'' the ''srotas'' or sites of occupation of [[vata]] are ''rikta'' (unfilled or spacious) and the aggravated [[vata]] fills the ''srotas''/site.

#In ''avarana'' of ''vata, swakarma vriddhi'' (exaggerated activities) of ''avaraka'' (covering ''dosha'') is manifested. The ''avrita'' (i.e. ''vata'') will show ''swakarma hani'' (diminished activity). This is the general feature of ''avarana''. Here the excessively increased strong ''avaraka'' suppresses the normal action of ''avrita'' (i.e. ''vata''). Therefore, when the obstruction is complete it may lead to the ''prakopa'' of ''vata'' resulting in the presentation of ''vata'' vitiated symptoms as well as its disorders[ Cha. Sa. [[Chikitsa Sthana]] 28/215, Chakrapani]. In case of ''gatatva'' the symptomatology will be predominantly of ''vata'' vitiation and pain is a common and chief complaint in all the conditions of ''gatatva''.

#Obstruction or covering of ''vata'' is possible by body components like ''dosha'' (''pitta'' and ''kapha''),tissues,food,  excretory products or mutual affliction of ''vata'' types. ''Gatatva'' of ''vata'' (affection) is happening in empty spaces or hollow cavities of tissues, their elements, organs and other body parts. In ''avarana'', the body component is in increased state causing fullness in respected channels, while in ''gatatva'' pathology, the body components are in depleted state casusing emptiness in the respected channels. ''Dhatugata vata'' will be presented with decreased quality of tissues associated with signs of vitiated ''vata''. Obviously, exceptions are possible according to the complexities of process of ''avarana'' or ''gatatva''.

'''Prognosis''': Exclusive ''vata'' disorders are serious and have poor prognosis. The symptoms / diseases explained manifest when vitiated ''vata'' affects vital parts. The therapeutic approaches should be cautious and extra efforts are essential for a better recovery. As the disease becomes chronic the curability rate drastically declines. The physical strength of the patient is also very important in determining prognosis. (verse 72-74)

'''General principles of management''': The general line of management of ''vatavyadhi'' applies to absolute ''vata'' vitiation only. If there is any association or obstruction of other dosha in ''vatavyadhi'', the treatment will be different. ''Kevalam'' term indicates pathology of vitiation of exclusive ''vata''. ''Nirupastambha'' is condition without any association of other ''dosha''. This pathology shall be primarily treated with oleation therapy.

As in exclusive ''vataja'' disease the major ''gunavriddhi'' is ''ruksha'' which leads to ''riktata'' in ''srotas'' and ''dhatu'' and more ''avakasha'' (space) for ''vata''; ''snehana'' is essential and ideal. Various methods for ''snehana'' are employed depending on ''avastha'' (stage), ''sthana'' (site) and ''bala'' (strength) of the diseases and as well as patient.

Repeated ''snehana'' and ''swedana'' therapies can control ''vata'' well. However, ''samshodhana'' (purification) therapies are executed to remove the residual ''dosha''. As ''shodhana'' has a definite chance for causation of ''vata prakopa'', the approach should be cautious, so ''mridu samshodana'' (mild purification) is done. ''Sneha virechana'' is done by ''tilwaka ghrita'' or ''eranda taila'', etc. ''Eranda taila'' is very effective in treating ''vata prakopa'' due to ''udavarta''. If ''virechana'' is not possible, ''anulomana'' diet should be adviced. If the patient is extremely weak ''niruha'' is better option. Even after ''shodhana''; recurrent application of ''snehana'' and ''swedana'' are essential.(verse 83-88)

==== Management of ''vata'' at different sites ====

==== Management of [[vata]] at different sites ====

Treatment of disorders of ''vata'', when located in different sites, habitat (''sthana'') is more important in comparison to the invaded (''agantu'') '''dosha''' e.g in ''koshthagata vata, koshtha'' is given preference in treatment, and so ''kshara'' is used which helps in digestion (''pachana''). But when ''vata'' is located in ''pakvashaya'' or ''guda'' which is ''vatasthana, udavartahara'' treatment is selected, which includes ''vata anulomana, basti, varti'' etc. In ''amashayagata vata, shodhana'' in the form of ''vamana'' is done.

=== Management of ''ardita'' (facial palsy) ===

=== Management of ''ardita'' (facial palsy) ===

The line of treatment of ''ardita'' aims at ''mastishkya'' (brain), therefore, ''nasya'' is indicated. ''Nasya'' is explained to be the direct entrance to the cranial vault. ''Nasya'' may be ''shodhana, shamana'' or ''brimhana'' as the case may be. But there is an opinion that since the word ''navana'' is used, it means ''snaihika nasya''. ''Murdhni taila'' is absolutely meant for treatment in head region and is of four types viz. ''abhyanga'' ( head massage), ''seka'' (pouring liquid on head), ''pichu'' ( therapeutic unctuous swab on head) and ''shirobasti''. ''Tarpana'' (nourishment therapy) is ''akshitarpana'' (nourishing eyes) and ''shrotratarpana'' (nourishing ears). ''Nadisweda'' is very specific in ''ardita'' and ''ksheeradhooma'' (medicated fumes of milk).

In ''pakshaghata, swedana,'' fomentation mixed with unctuous material and ''virechana'' or purgation therapy with unctuous substance is indicated. ''Virechana'' is the line of treatment in ''pakshaghata'' and outweighs ''basti'' which is said to be ideal for ''vatakopa''. ''Pakshaghata'' may be understood as a concealed ''urdhwaga raktapitta'' (bleeding from upper orifices of body) in which the only and effective choice is ''adho-shodhana'' (purgation). ''Gridhrasi'' is a tendon and ligament disorder and ''shastra, kshara,'' and ''agnikarma'' are the main line of treatment. Therefore ''siravyadha'' (blood letting) and ''dahakarma'' (cauterization) is advised. ''Basti'' is also a good choice since ''pakvashayagata vata'' leads to ''kateegraha'' and ''gridhrasi''.

''Agnikarma'' relieves muscle spasm thereby reducing pain whereas ''siravyadha'' may be helpful by reducing the blood stasis. Improved circulation removes cytokines and other inflammatory factors thereby reducing pain. (99-103)

=== Importance of site of affliction in treatment ===

=== Importance of site of affliction in treatment ===

The specificity of treatment depends on the site of affliction and the associated morbid tissues. For example masthishkya is very specific for ardita, pakṣāghāta, indriyagatavāta etc. Even though vamana is kaphahara, it is exclusively indicated in āmashayagata vāta taking into account of site of affliction. (verse 104)

Balā is excellent for lone vitiated vāta. The head of goat is indicated on the basis of the principle ‘sāmānyam vridhikārānam’(like increases like). These also explain the awareness of utilization of brain of goat in degenerative brain lesions. Lavana relieves stambha (stiffness) and samghata (conglomeration). Upanāha is also prepared with such well fomented flesh and added with different oils, salts etc. Such upanāha are brimhana. (verse 106-108)

Avagaha (immersion) sweda:

Avagaha (immersion) sweda:

Avagāha is typically indicated in apāna vāigunya (defects due to apana vata vitiation), it is a type of drava sweda (liquid fomentation). Nādisweda is also an excellent option for all types of vātarōga. Poultices (upanāha) of different types  provide self generated heat to cause swedana. It is by virtue of various dhanya (cereals) and kinwa (yeast) available in it.  (verse 109-118)

Pinyaka taila is a preparation in which rūkṣa guna is imparted to taila and is highly useful in kapha associated Vātavyādhi. (verse 136-137)

Pinyaka taila is a preparation in which ruksha [[guna]] is imparted to taila and is highly useful in [[kapha]] associated [[Vata]]vyadhi. (verse 136-137)

Importance of oil in treatment of vata: By virtue of vyavāyi guna (pervading/diffusive), it reaches the different interior parts of the body without any metabolic changes. By processing taila can adopt any type of qualitative changes.  The drugs are potentiated by repeated processing in its own media. Drugs like ksheerbalā (101 āvartita), dhanwatharam (21 āvartita) etc. are worth mentioning here. This approach of samskāra makes snēha as sukshma snēha (with better bio-availability and penetration) .(verse 181-182)

Thus [[raktamokshana]] and basti cikitsā which is useful in vātarakta is also helpful in rakta avruta [[vata]].  

Prameha samprapti mentioned in Sutra sthana 17th chapter explains kapha, pitta, meda and mānsa which when increased causes āvarana of vāta. Therefore, pramehagna cikitsā is helpful in meda āvr̥ta vāta and also in mansāvr̥ta vāta. Hence in mansāvr̥ta vāta the pipilika iva sanchar (tingling sensation) reduces, if prameha is treated. Similarly, in obesity, medasāvr̥ta vāta (vata obstructed by excess meda) [Cha.Sa.[[Sutra Sthana]] 21/5] and meda and mānsa ativridhi [Cha.Sa.[[Sutra Sthana]] 21/9] is observed.  These conditions are best treated on the principles of management of prameha, sthaulya associated with vitiated vata. Therapeutic emesis to expel out the intoxicated food in stomach is advised in condition of annavrita vata ( vata obstructed by food). Pāchana and deepan helps in digestion and also pacifies vāta.

Therefore, pramehagna cikitsa is helpful in meda avruta [[vata]] and also in mamsavruta [[vata]]. Hence in mamsavruta [[vata]] the pipilika iva sanchara (tingling sensation) reduces, if prameha is treated.

Hot foementation reduces urethral pressure. A study done by Shafik A.  showed that sitting in warm water helps in micturition which seems to be initiated by reflex internal urethral sphincter relaxation. A thermo sphincter reflex is likely to be involved.

Uttara basti effect is similar to catheterization. Further depending on the medicines used for uttara basti, tridōṣa shamāna can be done.

The lines of treatment of raktagatavāta and raktvritavāta as well as śukragatavāta and shukrāvr̥ta vāta are one and the same irrespective difference in samprapti as gatavāta or āvr̥ta vāta. It is because of the fact that rakta and śukra are mobile and comparatively pervaded all over the body like vāta so gatavāta and āvr̥ta vāta are mutually complimentary here.

Finally, the treatment strategies of anyasthānagata(in other sites) vata are explained. The importance is given to sthanastha dosha (in own sites).(189-199)

Movements of vata and concept of anyonyavarana:As discussed earlier avyāhatagati (free movement) is a cardinal feature of vāta to perform normally. In āvarana certain obstacles like dosha, dhātu or anna etc which are immobile, occupy the pathway of mobile vāta. It is not mandatory that such immobile articles only cause obstruction to vāta. If the individual sub types of vāta are considered prāna, udāna, vyāna, samāna and apāna are mobile and has some specific direction for their gati. For example, prāna has movement from murdha (head) to downwards. Udāna has movement from uras(chest) to upwards.  Vyāna moves upward downward and sidewards like rasa. Samāna moves around jatharāgni. Apāna move downwards from pakvāśaya. This can be further analysed as follows.  Udāna possess upward movement.  Likewise ‘apāna’ has downward direction.  Vyāna vāyu moves in horizontal direction (vyāpanat vyāna uccyate) along with upward and downward directions as rasa samvahana (circulation) is concerned.[19]Samāna is also having such qualities to equally distribute the nutrients through out the body.  Prāna has multi directional gati. So, the movements of individual subtypes of vāta are directional in nature. When these meet in opposite direction it makes anyonyāvarana. For example prāna and udāna meet opposite and interfere with mutual normal movements leads to difficulty in inspiration as well as expiration which is comparatively irreversible. This concept is called anyonyāvarana. It is of 20 types taking into account of 5 diiferent types making 4 particular combinations. Anyonyāvarana are comparatively difficult situations. (verses 199-206)

Anyonyāvarana is characterised by Svakarma hani or vriddhi (either increase or decrease in functions) which depends on the nature and site of anyonyāvarana (mutual covering). For example prānaāvr̥ta udāna may lead to difficulty in respiration, followed with cardiac symptoms, aphasia or dysarthria and some times upper respiratory symptoms. This presentation is comparatively acute in onset and. Here the functions of udāna are masked by prāna. But in  udānaāvr̥ta prāna the symptoms are loss of motor power, immunity and complexion leading to death. Here the functions of prāna are seriously hampered. This symptom may be acute or chronic in nature. When apāna got āvarana by udāna the normal peristalsis is hampared and anulomana is the line of treatment. In apāna āvarana to udāna increased bowel motility can be seen grāhi is the line of treatment which should be adopted here.

Rehabilitation of vata: Prakr̥tisthāpanam means re-establishment in its own pathway (sva mārgaga)/ or in its own place (sva sthāna gamayed enam). Therefore for udāna vāyu, vamana etc. treatment should be administered to regulate the normal functional status of udāna vāyu. Apāna has adhogati, therefore anulomana chikitsā should be done, thereby regularizing the urdhva apāna bhava of Apāna vāyu. Shamāna should be line of treatment for samāna vāyu. Empowering digestive power should be done. Samāna being sited near agni, proper digestion and absorption of essential elements will be observed. Proper electrolyte balance will be maintained, thereby maintaining the pH of body fluids. As discussed previously vyāna has all the three gati i.e. urdhva, adho and madhya gati. Here the general line of treatment of anyonyāvarana is discussed. (verse 219-221)

Importance of udana and prana vata:

Importance of udana and prana vata:

Among various āvarana, the involvement of udāna and prāna are very important. As explained in the introductory comments, prāna is life and udāna is strength. These are very vital issues as far as āvarana is concerned. Improper management or avoidance of treatments may lead to permanant disabilities in Āvarana.  (verse 231-236)

Complications of āvarana:  

Complications of Avarana:  

This includes hr̥drōga, vidradhi, plīhā, gulma, a'tīsāra. Hr̥drōga is a common complication of ill treated āvarana of prāna and udāna. Vidradhi and plīhā are caused by wrongly managed āvarana of vyāna. Gulma and atīsāra are common complications of āvarana of samāna and apāna.  

This includes hrudroga, vidradhi, plīhā, gulma, atisara. Hrudroga is a common complication of ill treated avarana of prana and udana. Vidradhi and pliha are caused by wrongly managed avarana of vyana. Gulma and atisara are common complications of avarana of samana and apana.  

Srotoshodana is an important line of management in Āvarana. It ensures unobstructed movement of vāta. All abhishyandi(..) food causes srotorōdha (obstruction of channels). Yāpana Basti is ideal for all age group and safe to severe clinical presentations. It protects all marma points. As it is neither lekhana (..), nor brimhana, it is useful for managing vāta as well as āvaraka kapha or pitta. Guggulu rasāyana and shilajatu rasāyana is ideal for many clinical conditions of āvarana.
