The term 'Desha' literally means country, site, location, land or region. In Ayurveda, 'Desha' refers to the site, area of residence or location of a person. It also refers to the body and mind of a person which are the sites of diseases. Ayurveda scholars have deeply studied the effects of the climate and other environmental factors of the region where a person resides on his/her health. Therefore, Desha has been considered as an important concept in Ayurveda which is taken into accounts while making a diagnosis, assessing strength and planning a treatment.  

Desha is one of the very important criteria used in the assessment of any patient in Ayurveda. In Ayurveda this term Desha has been applied and described in two dimensional way. Bhumi Desha (भूमिदेशः। Specific part of land or geographical part) and Atura Desha (आतुरदेशः । the site of disease  body  and  mind) are the 2 different entities referred by the term Desha.  In  reference  of  place of residence, architecting, collection of  drugs,  quality  of  river  water, property of air etc. Bhumi Desha is indicated.  Whereas, in terms of examining a patient, locating the sites of assessment of patient, Atura desha is indicated. <ref name=":0">Meena, Dinesh & Singh, Rani.

The term Desha is derived from the root term Disha (दिश). Disha  is  further described as  ‘Dish  Nirdesh’ (दिश निर्देशे) . It  has been  considered  in  nine ‘Karana Dravyas’ (कारण द्रव्याणि) in the Bharatiya Shastras, Darshanas and Ayurveda. <blockquote>दिश्यते निर्द्दिश्यते इति । दिश निर्द्देशे + कर्म्मणि घञ् ।) भूगोलभागविशेषः । (Shab. 2.747)<ref>Shabdakalpadruma [https://sa.wikisource.org/wiki/%E0%A4%B6%E0%A4%AC%E0%A5%8D%E0%A4%A6%E0%A4%95%E0%A4%B2%E0%A5%8D%E0%A4%AA%E0%A4%A6%E0%A5%8D%E0%A4%B0%E0%A5%81%E0%A4%AE%E0%A4%83/%E0%A4%A6%E0%A5%81%E0%A4%B0%E0%A5%8D%E0%A4%97%E0%A4%BE%E0%A4%A7%E0%A5%8D%E0%A4%AF%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%83 2.747]</ref></blockquote>Disha (direction) denotes Desha also which is directed or divided from one part to other. <blockquote>देशः पुनः स्थानं; स द्रव्याणामुत्पत्तिप्रचारौ देशसात्म्यं चाचष्टे (५)|२२| (Char.

== The specific Desha, climate, dietic culture and specific diseases ==

== देशविशिष्ट आहारः तथा रोगाः च ॥ The specific Desha, dietitic culture and specific diseases ==

There are few examples in Classical Ayurveda texts where, acharyas describe how people residing in a particular desha have certain tendencies in their diet patterns  and how this makes them more prone to suffer from particular diseases that develop due to excess consumption of certain rasas. Example of desha of Eastern sides is given. Acharyas mention that people residing in eastern regions have excess consumption of ksharas (strong alkali dominant). Ksharas are said to be very harsh and penetrating in nature as well as aggravating Pitta and vitiating rakta dhatu. Thus soft tissues and organs like eyes , heart, reproductive tissues are predominantly affected. As a result they suffer from blindness, impotency, baldness, grey hair and heart disease in lage numbers as compared to people residing in other deshas. This could be the observation of acharyas in the period when the texts were written. Similarly one more such example is mentioned wherein excess salt intake by people residing in deshas like Balhika, Saurastrika, Saindhava and Sauviraka is mentioned. Excess lavana rasa is diet thus make these people more prone to develop health conditions like fatigue, lassitude and weakness.<ref>Charaka Samhita (Vimanasthanam Adhyaya 1 Sutra 17-8)</ref><ref name=":0" /> Therefore Desha is considered as one of the important criteria in [[10 fold clinical examination in Ayurveda (दशविधपरीक्षा)|10 fold clinical examination]] in Ayurveda diagnosis. Because it helps physician understand the possible cause and plan treatment effectively.

One more disease known as Shlipada (equivalent to Filariasis or elephantitis) is said to be predominantly originating in Anupa desha where there is always a collection of stagnant water dampness throughout the year. One can find that such conditions are usually not commonly found everwhere but in specific region that is Desha as mentioned in Ayurveda, number of cases suffering from this are observed. This is the effect of land on health of the individuals residing on it. <ref>Murthy, K.R.

The concept of Deshsatmya discussed in Ayurveda is important to understand the desirable diet and lifestyle for people residing in that region. Whatever diet and lifestyle help in maintaining the balance of doshas and dhatus in a person residing in the desha having particular properties, is known to be Desha satmya for him/her. <blockquote>देशसात्म्येन च देशविपरीतगुणं सात्म्यं गृह्यते; यथा- आनूपे उष्णरूक्षादि, धन्वनि च शीतस्निग्धादि, ओकसात्म्यं तु उपयोक्तृग्रहणेन गृहीतम्|| Chakrapani Cha. vi. 1.22</blockquote>Meaning: Deshasatmya refers to having used to or accustomed to the diet which is opposite in properties to that of Desha. e.g. Diet in ushna( Hot) and ruksha (dry) properties is satmya in Anupa desha, shita (cold) and snigdha (unctous) in Janhgala desha.

The equilibrium of Doshas is known as health. The first and foremost principles of disease treatment is avoidance of the cause of diseases. Therefore if someone takes substance (diet/ medicine) of similar quality of Desha, Doshas will be aggravated leading to diseases. The scholars of Ayurveda have directed to use Ahara (diet) and Vihara (life style) opposing to Desha. There is a specific concept in Ayurveda entitled Viruddha Ahara which indicates 18 types of Ahara (diet patterns) that are incompatible for health. One of them is Desha Viruddha according to which the Ruksha (dry) Ahara in Jangala Desha is Desha Viruddha because if natures of both are similar it will aggravate Doshas. The quality of drugs are also described according to Desha.
