Abstract

Right diet is the essence of disease prevention and the foundation of a healthy and happy life. A properly selected diet and diet plan plays a critical importance in the management of any disease. The usage of Yava or barley (Hordeum vulgare L.) both as Pathya (wholesome) and Aushadha (medicine) is established in ancient texts and modern research experiments. Yava is in practice since time immemorial due to its rich nutritional entities and various therapeutics benefits. The present review details Rasapanchaka (five attributes of dravya beginning with rasa), Rogaghnata (therapeutic indication) and utility of Yava as a Pathya depicted in Samhita, Sangrahagranth, Nighantu, and Rasagrantha. Yava is advocated as Pathya in 117 different disease conditions, nine swastha condition, and during the treatment course of six other medications. A total of 108 Ahara Kalpana (food dietetics preparations) of Yava has been found, among them 95 Ahara Kalpana having internal uses, 12 Ahara Kalpana having external uses and one Ahara Kalpana having both internal and external uses. It is found to be used in Swastha and 48 different disease conditions among them maximum formulations have been found in Prameha, Trushna, Jwara, Kasa, etc. Yava is contraindicated in persons suffering from Amlapita (dyspesia), Grahani (malabsorption syndrome), and during the administration of Gandhaka rasayana. Yava is highly useful grain which should be consumed to promote health of individual and prevent disease conditions.

 Introduction



Ayurveda is one of the world’s oldest holistic healing systems. It was developed thousands of years ago in India. Ayurveda deals elaborately on Pathya (wholesome) and Apathya (unwholesome) its importance of Doshas (regulatory functional factors of the body) and bringing harmony within the body. According to Ayurveda as well as modern science, diet plays an important role in the etiopathogenesis of disease. Acharya Kashyapa has quoted that there is no medicine like food.[1] Only a balanced diet can cure numerous disorders, even good medicines are unable to cure certain diseases without a balanced diet. That is why food is said to be the most important medicine. Acharya Lolimbaraja has mentioned that “when an individual follows proper diet, why does he need medicine? When an individual does not follow a proper diet, what is the use of medicine?” in his work Vaidyajeevanam.[2] More attention should be paid to Pathya along with the treatment. More attention should be paid to Pathya along with the treatment, through Ahara (food) and Vihara (lifestyle), for the maintenance of wellbeing and restoration of health. Pathya is a group of precautions related to diet and prescribed along with medicines in the treatment of a disease. Pathya for Atura (diseased) is explained in respective diseases throughout the samhitas and chikitsagranthas.

Acharya charaka mentions the synonyms of Chikitsa (treatment) as Vyadhihara (removal of disease), Sadhana (practice toward mitigating the cause and effect of the disease), Aushadha (medicine), Prayaschita (repentance), Prashamana (subsiding disease), Prakrutisthapana (restoration of health), Pathya (wholesome), and Hitam (conducive to health).[3]Pathya is also one among them.

Yava (Hordeum vulgare L.), commonly known as barley, belongs to the family Poaceae. It makes up to 12% of total cereal production and owns the fourth position after wheat, rice, and maize. It is one of the oldest grain crops. It is cultivated extensively in all countries of the world. Its origin is considered in the Middle East.[4] It is used as a food grain well known to the present era since the Vedic period. It not only provides nutrition but also it has medicinal properties.

There is a detailed description of Yava in various Samhita and Nighantu. Acharya charaka discussed about Ahara in swastha chatushka, Annapana chatushka, and at many more places in different context, which shows the importance of Ahara. Acharya classifies Ahara in 12 vargas in Annapana vidhi adhyaya of Sutrasthana,[5]Yava (Barley) has been discussed under the Shukadhanya varga of this classification. Yava is considered as one among the Nitya sevaniya dravya (wholesome daily food),[6] a Shukadhanya. Among all the Pathya dravyas (wholesome substance), yava is given foremost importance in all the classics. Yava is used as a part of various therapeutics preparations as well as in dietary form for many Roga (disease).

This paper reviews the classification of Yava in Ayurveda texts, Rasapanchaka (five attributes of dravya beginning with rasa), Karma (action), Rogaghnata (therapeutic indication), Nutritional evaluation, Yava as Pathya in diseases, and various Aharakalpana of Yava in diseases condition.

 Materials and Methods

There is a detailed description of Yava in various Ayurvedic Samhitas and Nighantus. Classification of Yava in various treatise is depicted in [Table 1].{Table 1}

Rasapanchaka and Rogaghnata

The action of the drug in Ayurveda is completely based on the Rasapanchaka of that particular drug. Rasapanchaka is an approach to portray the pharmacodynamics of Ayurvedic drugs, which covers five aspects: Rasa (taste), Guna (attribute), Veerya (potency), Vipaka (bio-transformed rasa), and Prabhava (exceptional activity) [Table 2].{Table 2}

Nutritional value

Nutrition is a vital component of the individuals and community health as nutritional well-being of life. Yava, that is, barley, is a versatile cereal grain, which is rich in macro and micronutrients. It fulfills the major requirement of the human body. The following nutrients are present in Yava[44] [Table 3].{Table 3}

 Discussion



On critical analysis, it is observed that use of yava as an ingredient in various dosage forms as Pathya kalpana has gradually been decreased from the period of Charaka (second BC) up to nineteenth-century AD. Maximum Aharakalpana were found in Vangsena (17) followed by Charak Samhita (16), Astanga sangraha (16), Sushruta Samhita (12), Astanga hruday (10), Yogaratnakara (10), Bhavaprakasha (8), Gadanigraha (8), Vrundamadhava (5), Chakradatta (5), Bhaisajya ratnavali (5), Bhela Samhita (4), Kashyapa Samhita (3), Sharangadhara (2), Chikitsa kalika (2), Vaidya Chintamani (1), Haritasamhita (1), Sahstrayoga (1), Basavarajeeyama (1), and Vaidya rahasya (1) [Figure 4].{Figure 4}

Yava (H. vulgare L.), commonly known as barley, belongs to the family Poaceae. It is one of the most fundamental plants in human nutrition. Yava is Kashaya – Madhura in rasa. Kashaya rasa decreases Pitta Kapha, purifies blood, absorbs the Kleda (moisture)-meda (fat), and performs Lekhana karma. Madhura rasa and Sheeta veerya increase Dhatubala of sharir (strength of major structural component of the body) and does Jeevaniya karma (vitalization). Katu vipaka absorbs Sneha (oleation), Meda, and Kleda present in the body. Guru guna increases the quantity of Mala (faeces), Mrudu guna helps in Softening of Mala, Picchila guna softens the elementary canal and helps in excretion. Purishajananakarma is caused by above-mentioned properties.

Yava (barley) is considered being most useful grain, as it is easily digestible compared wheat and other grain. But still it remains underutilized as human food.[45]Yava is an efficient food to prevent and cure many lifestyle disorders. It is found ancient cereal with various active principles including vitamins, minerals, and amino acids have been used by the physician in the form of a wholesome diet to treat various diseases. Nutrition plays a pivotal role in ayurevdic living. It is difficult to understand ayurvedic nutrition from the western point of view where quantity is determined by serving size or in caloric intake. Modern science states that carbohydrate, fat, protein, vitamins, and mineral are required for a well-balanced diet. In Ayurveda various activities such as immunomodulator, and nutritional that enhance the strength, immunity, bulk of the body resulting by the use of medicinal or dietary substances are termed as Balya. Yava having Balya, Medhya, Varnya, Vrushya, Jeevaniya, and Sthairyakrut karma denotes that it is a rich source of nutrition.

 Conclusion



Ayurvedic pharmacodynamics is indicative to prevent and cure many diseases. It is a time to reintroduce the barley again in the main diet, based upon its Ayurvedic pharmacodynamics, to prevent and cure many diseases. This cereal may play an important role as Pathya in many diseases. Present findings may be helpful for its daily use to promote health of individual and prevent disease conditions.
