Why Ayurveda physicians do emphasizes on Jatharagni?? Why Agni is the crucial part of physical, physiological and mental health?
Panchmahabhuta: Every entity of the universe is formed with the combination of panchmahabhuta (five basic elements in this universe): prithvi (earth), aap (water), tejas (fire), vayu (air) and aakash (ether). The three dosha (VPK) collectively known as tridosha, have a specific relationship with these five elements. In other words, every entity, living or non-living, is panchabhautik (made up of five basic elements) and has properties of these doshas. It is said that kapha is the creator, pitta is the transformer and vata is the destructor in nature. The body constitutes of tridosha (three humours), saptadhatu (seven tissues) and trimala (three excretes). And they have their traits/properties which show particular actions and effects on human beings according to prakruti, age, seasons, geographical areas, and food.
Jatharagni: Jatharagni is very important as it is responsible for digestion and nourishment (also under-nourishment) of tridosha, saptadhatu, trimala and sharir bala (body strength). Out of panchmahabhuta, tej is present in jatharagni and grahani (duodenum) is its site. It is placed behind nabhi (umbilicus). The samana vayu (one of the five subtypes of vata dosha) and pachak pitta (one of the five subtypes of pitta dosha) work together for the digestion of food, and then the absorption and circulation of the digested food (also known as rasa dhatu). It is carried further by vyana vayu (one of the five subtypes of vata dosha). The excretion of mala through intestines is done by apaana vayu (one of the five subtypes of vata dosha). Note that the balanced hunger, digestion, and circulation of rasa dhatu and nourishment of all further dhatus is possible only when the jatharagni is in the balanced state. Imbalanced jatharagni is the cause of many disorders and diseases (especially with the changed lifestyle of the 21st century).
Effect of rutu and prahar on dosha: Every season is dominated with some dosha and its properties (called as guna). Vata dosha accumulates in Greeshma rutu (a part of summer season) and increases in Varshaa rutu (a part of rainy season), pitta dosha increases in Sharad rutu (a part of autumn season) and kapha dosha accumulates in Shishir rutu (a part of spring season) and increases in Vasant rutu (a part of spring season). Further, during the day also there are cycles of 4 hours in which each dosha plays a significant role. From 6 am to 10 am in the morning (also 6 pm to 10 pm at night) kapha dosha shows dominance; from 10 am to 2 pm in the afternoon (also 10 pm to 2 am at night) pitta dosha shows dominance; and from 2 pm to 6 pm in the evening (also 2 am to 6 am in the morning) vata dosha shows dominance. The combination of such environmental dominance plays a significant role in our daily actions and reactions.
Types of jatharagni: The balanced state of jatharagni is known as samaagni (balanced fire) which ensures complete digestion of the food ingested at the proper time without any irregularity. Its activity is neither too intense nor too weak. It is just appropriate and therefore, is ideal too. When it is not balanced, it is of one of the three forms: tikshangi, vishamagni or mandagni. Few of the symptoms of imbalanced jatharagni are arochak (anorexia), kshudanash (loss of appetite), arasdanyata (tastelessness), apachan (indigestion), chardi (vomiting), hrullas (nausea), atisar (diarrhea), and malavashambha (constipation). The imbalance is caused typically due to imbalanced or vitiated pitta, vata and kapha dosha. This may further lead to vitiation of maanas bhaav (mind) and saadhak pitta (one of the five subtypes of pitta dosha) showing irritability, anger, hyper thinking, nervousness, or depression.
Rutucharya: We eat every day according to our likings and habits. However, Ayurveda specifies rutucharya and dinacharya (daily regimen) considering the effects of rutu, month, time on our body and to make sure the food is digested in the most efficient way for the full nourishment of body and mind. The whole year is divided into aadaan kaal (period which takes away body energy/strength) and visharga kaal (period which provides energy/strength to body). In aadaan kaal, the sun is very strong, it absorbs all moisture from the earth. So the tikshna (sharp), ushna (hot), and ruksha (dry) gunas increase in our body. Also, the sharir bala reduces gradually. So, we can say there is in general poor nourishment of dhatu and jatharagni during this time frame. On the contrary, visarg kaal is predominant of the moon and so mild and sheet (cold), snigdha guna (moist/unctuous) increases in our body. We get energy from nature which in general increases our jatharagni and bala (strength) too. In fact, jatharagni is usually the lowest in Greeshma rutu and Varsha rutu.

PCT Application NO: PCT/IN2017/050217 Title: A DEVICE FOR THE DETECTION AND RELIABLE CAPTURING OF THE PULSE CHARACTERISTICS 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, and responses of a subject to structured queries to arrive at the tridosha levels in a subject.
