The Ashtvidhpariksha is a very important diagnostic instrument mentioned in Ayurveda. This Ashtvidha Pariksha is incomplete without Nadi Pariksha. The Prakruti-Vikruti, the condition of doshas in each organ, and the impacts on Dhatus, Manas, and Sukshma Sharira can all be determined using Nadi. The effects and current status of Vata-Pitta-Kapha, which constitute the basis of Ayurvedic diagnosis and treatment, can only be assessed by Nadi Pariksha. Nadi Pariksha can also be used to learn about Bhutpreta Badha, which is referenced in Ayurveda. Our ancient literature includes knowledge of Nadi in the form of shlokas. The material in the shlokas is written in a flowery language and is not very clearly conveyed. As a result, it can only be understood with the help of a guru. There is no mention of Nadi vijnana in our ancient writings, such as Brihatrayi. The earliest text to establish the authenticity of Nadi Pariksha was the 13th-century Sharangdhara Samhita. Then, in the 16th century, the 'Bhavprakasha' documents some progress in the field of Nadi Vijnana. Data and information regarding Nadi Pariksha may be found in Yogratnakara from the 17th century. This study aims to impoverish cognition, and a small attempt has been made to do so.
In Ayurveda, Pinda Brhmanda Nyaya and Anshansha Kalpana are two hypotheses examined. According to the Pinda Brahmanda Nyaya, whatever elements we perceive in nature are also found in the tiniest areas of the human body and vice versa. According to Anshanshakalpana, all the elements contained in any creature are found in the seed of that organism in the same proportion but in minute quantities. The existence of a pulse at the Angushthamula indicates that life is there. "Hastagatenadisarvanroganprabhashyate." The purpose of Nadi Pariksha is to assess and estimate the amount of Tridosha in the body. The three basic doshas, Vata, Pitta, and Kapha, are considered the most important. The concept of Nadi Pariksha may be found in several ancient Ayurvedic Samhitas, including Bhavprakash, Ravansamhita's Nadi Pariksha, and Kanad's Nadivigyan. Theacharya Sharangdhara popularized it in his work as a diagnostic and prognostic tool. In the first half of the third chapter, the notion of Nadi Pariksha is explained. In the first chapter, under the term "Rog Pariksha," Yogratnakara also describes Nadi Pariksha as a diagnosis. According to Yogratnakara, the Nadi Pariksha (Pulse Examination) can reveal numerous disorders. These variables are indicative of illness diagnosis. They were once widely utilized diagnostic instruments, but they are no longer so, necessitating the necessity to re-establish their results so that they might be used in the future.
One of Ayurveda's most important diagnostic tools is Ashtavidha rogi pariksha. For disease diagnosis, Acharya Yogaratnakara described eight types of rogi pariksha: nadi, mutra, mala, jivha, shabda, sparsha, and drik. Among these, nadi pariksha is required to detect altered dosha conditions such as decreased or hyperfunctioning doshas and mixed or normal dosha function. The nadi pariksha sheds light on the complete state of diseases. This work aims to investigate the relationship between nadi pariksha (pulse examination) and ashtasthana pariksha in therapeutics, with a focus on its relevance in medical practice.
Before treating a patient's ailment, it is critical to establish a precise diagnosis in the Ayurvedic system, and this job is done successfully through Nadi Pariksha. Therefore, it's crucial to understand the Nadi Pariksha and the Nadi Vigyana. In ancient Nadi and Ayurvedic literature, the concepts of Nadi Pariksha and Nadi Vigyana have been described. With the help of three fingers of his hand, the Nadi Vaidya performs the Nadi Pariksha. The accurate diagnosis of the sickness (VyadhiVinischay) is made by knowing the position of the Doshas through Nadi Gatiin, the patient's thumb root. Nadi Pariksha was an important method of ancient Ayurveda Vaidyas, and vaidyas are still using it to diagnose diseases today. Acharya Kanad, Vaidya Ayodhyanath Pandey, and Vaidya Tara Shankar Mishretc. They have presented varying and precise descriptions of Nadi Vigyana and Nadi Pariksha in the Nadi literature. Sharangdhar Samhita, Bhavprakash, and Yogaratnakar are among the Ayurvedic literature that describes Nadi Pariksha in detail.
The Traditional Medicine System (TMS) considers Nadi Pariksha (Pulse Diagnosis) the most significant health monitoring assessment. Pulse analysis is subjective and difficult to measure. Due to its arbitrariness, it is difficult for an Ayurvedic doctor to understand the pulse from his viewpoint. Standard methodologies and instruments are critically needed to properly recognize TMS. Researchers have investigated pulse sensing and analysis in light of the growing popularity of traditional and alternative medicine worldwide. However, the results of studies are not oriented in one direction due to a conflict between research goals, techniques, and statistical tools used. This study looks at how researchers have been interpreting pulse signals utilizing the most up-to-date electronic signal processing techniques. This study aims to develop pulse sensing and analysis methodologies that use cutting-edge technology to aid or assist Ayurvedic practitioners in promoting our country's traditional pulse sensing. Because no sensor has yet been established as a standard for wrist pulse detection, various sensors were tested to measure wrist pulses, and the results were compared to previous studies. The best results were obtained using the optical sensor HOA 709 in reflective mode, which caught minute details and acquired pulse signals from healthy volunteers at the Pita spot on the radial artery. The sensor was further investigated by recording pre-and post-meal data from two patients, and considerable signal contour variation was seen. It can be further investigated with the help of Ayurvedic experts to extract new parameters and make them useful in health treatment.
