Ayurveda has its origin in ancient Indian civilization. While the origins might be old, its effectiveness is still prevalent and acknowledged by western and allopathic medicines. Ayurveda, unlike other science of medicines, looks at an individual's vulnerability (patient-centric approach) towards a disease instead of the disease itself and works on solving from the root cause. It's knowledge is mainly derived from the theoretical foundations that lie in the compendium of wisdom of the Vedas and is comprehensively blended through its subjective, objective and intuitive form.

The concepts of ayurveda, like those of Vedas, are therefore universal in nature beyond the realm of space and time. It stresses on the fundamental understanding of the interrelationship and correspondence between the macro cosm (Bramhanda) and the living entity as man or microcosm (Pindanda). At operational level, it supposes human health or wellness as a product of equilibrium between these two prakruties. Prakruti, in itself, is conceived to consist of what is broadly referred to as vata, pitta, and kapha. When in equilibrium they are the needed and desirable constitution for human health. Any deviations or perturbations in their equilibrium manifest as disease or disorder. They are therefore also called as ‘tridosha’ and the philosophy of ayurveda is to re-establish the equilibrium using its remedial measures.


TRIDOSHA: The Basis of Inspection

The tridosha’s viz. vata, pitta and kapha have their specific role, function and character.

  • Vata is associated with motion including the internal and/or external movements of the body. It therefore has a control over respiratory, circulatory, digestive and excretory functions of the human body at all levels ranging from cellular, tissue to organ.

  • Pitta controls all the chemical and biochemical transformations including thermal and metabolic exchanges. Its function is thus to provide vital organic/inorganic matter to the body.

  • Kapha reflects the building-up processes of the body. Taken together they control, mediate, regulate and equilibrate the processes that help in vitalization of matter and materialization of life and health.

Observation, sensing, experiencing and examining - Nadi - the pulse- gives the physician an enormous insight into the functioning of the various processes and mainly regarding their deviations from the desirables. It is a one to many type of mapping and requires the physician (user) to attain the skills of pulse examination in all its dimensions. Authoritative texts from the early period such as Sarnagadhara Samhita (13th AD), Bhavaprakash (15th AD), Yogaratnakara (16th AD) etc. describe in detail the nadi parikshan. The active and living tradition continues in a guru-shishya mode. The examination of nadi can reveal different diseases, their stage, severity, manifestations in organs or parts of the body, possibility and span of recovery etc. It can fully bring out genetic, predisposing, triggering and perpetuating factors. Pulse can reveal the state of embryo in the mother’s womb and its evolution, the status of health from past to present, physiological and emotional make-up of patient, constitutional blend, cognitive power, means for promotion of health, diseases of unknown etiology etc.

Nadi tarangini provides an unparalleled insight into individualized healthcare management. Nadi Tarangini auscultates subtle changes in overall health parameters based on Vatta, Pitta, Kapha (Tridosha) diagnostics. The Nadi Tarangini report envisages present and possible ailments, giving recommendations on diet and lifestyle changes. The unique sensor technology to translate ancient wisdom of understanding individualized health parameters in Ayurveda and advanced Data Science make Nadi Tarangini a perfect tool for individualized diagnostics. Refer for more information.


This individualized report is generated based on the individual’s Nadi (pulse) readings while also taking into consideration variations due to geographical location, and climatic conditions. The report includes an explanation of the individual’s Prakriti (balance in Tridosha). The Nadi examination is shown in the form of a graph which simplifies Nadi pariksha for prognosis and diagnosis. Furthermore, diet and lifestyle changes are suggested based on the current Prakruti and Vikruti (imbalance in Tridosha). With this seamless integration of Nadi Tarangini data generated through reports, the Prakruti can be monitored regularly. Data analysis of the report enables prediction of possible ailments and early detection making Nadi Tarangini a health-centric diagnostic technology.

Total data collection on the Atreya’s centralized server is more than 1,30,000 users pulse data. We applied the latest scientific statistical and machine learning algorithms on this data to validate its significance WRT the ancient shlokas in Ayurveda. We have published more than 35 technical papers based on our revolutionary patented sensor technology in peer reviewed journals and renowned conferences (Please see the list at the end of this page). These papers and our proprietary algorithms make the scientific base of our Turyaa Wellness platform.

We systematically did 3 sets of beta trials during 2018 to 2020

  • The first trial of the Turyaa Wellness was executed on 10 subjects (all of them for the Metabolic goal: Weight and Acidity issue) and main intervention was through the diet. In this trial, the nadi was recorded on the Nadi Tarangini system and the tongue was recorded on the “Lola app”. Lola means tongue in Sanskrit. We also showcased it in the renowned conference “World Ayurveda Congress” 2018, and received a very positive response. [The Lola app is not active anymore, but it’s functionalities have been included in the Turyaa app.]

  • The second trial of Turyaa Wellness was executed on 22 subjects (all the Turyaa goals) and main intervention was through diet and yoga. In this trial, the nadi was recorded on the Turyaa prototype units and all personal, medical, family information and tongue photos were recorded on the Turyaa prototype app.

  • The third and final trial of Turyaa Wellness was executed on 25 subjects (all the Turyaa goals) and a full recommendation system was established comprising diet, yoga, music, sleep, water and coach interactions on video calls. Every user’s fortnightly reports were shared with the users to track their progress and at the end of the 3 to 4 months course, their testimonials were recorded.

Based on the machine learning based findings from the server and the learnings from the beta-trials, we have launched the revolutionary Turyaa Wellness Platform; first of its kind holistic platform where data of Trividh Pariksha (Darsham - to see, Sparsham - to touch, Prashnam - to question) of Ayurveda will be analyzed for providing the personalized experience.

Abstract: The invention is related to a device to sense the pulse on a wrist of a subject and to arrive at the health status of the said subject by capturing the pulse in real time; analyzing the pulse based on time-frequency properties of the pulse signal and Vata, Pitta and Kapha humors of the subject. The device reliably detects and captures noise free pulse characteristics of a subject at the appropriate locations of the subject's wrist with minimal positional error in a user friendly way with minimal reliance on the expertise of the person measuring the pulses. The device facilitates the analysis of the pulses and provides a comprehensive diagnostic system based on the pulse characteristics, visual features, responses of a subject to structured queries to arrive at the tridosha levels in a subject.Dr. Aniruddha Joshi (Atreya Innovations). A device for the detection and reliable computation of the pulse characteristics. Submitted.
