Experimental Studies

Join us in making a real difference.

In order to establish efficacy of Yagya on various environmental and health aspects we have conducted a series of experiments in collaboration with Central Pollution Control Board (CPCB), Delhi and using authentic digital devices. The aim is to create awareness among the people for taking responsibility of their actions and then adopt Yagya in their daily lives as an environmental purification tool and complete health restoration measure. Summarised experimental studies conducted and their results are given below.

Abstract of Research work done by Dr. Mamta saxena

In an endeavour to find some solution which is effective and long lasting for this environmental problems causing serious health hazards,  the Vedic science of ‘Yagya’ was chosen for the necessary experimentation to see if it actually helped in the reduction of air pollution as mentioned in the ancient books. All the experiments were conducted in collaboration with Central  Pollution Control Board, Delhi, who provided necessary Lab support for these studies.

  In all the experiments,  the effect of Yagya was studied on the atmospheric odour, on the air microflora and also on the gaseous pollutants like NO2, SO2 and RSPM. To study the impact of Yagya on air microflora,  several experiments were conducted both indoor and outdoor,   some experiments were also conducted simultaneously to compare the effect of Yagya and that of non-Yagya i.e. by just burning plain herbs with mantras and rituals at one place and burning plain wood in the other place was studied.

The research findings indicate  that the process of Yagya is effective in the reduction of air pollution both gaseous and microbial and also removes the bad odour, if any, at the place. It is also capable of containing harmful polluting gases in the atmosphere. It is thus a tool for restoring health of humans and all animal beings. It is also seen that the effect of Yagya remains in the atmosphere for days after it has actually been performed. Hence we see that ‘Yagya’  is probably the only possible solution for today’s health problems.

Abstract of Research work done by Dr. Meenakshi Raghuvanshi

“Yagya” is popular as a Vedic fire-ritual. Those familiar with the Vedic Sciences know that, if conducted with proper choice of fire-pit, medicinal woods and herbal preparation Yagya serves as an effective natural mode of environment purification and herbal inhalation therapy.


Repeated rhythmic chanting of mantra and deep breathing, oral and nasal inhalation of medicinal vapors/gases/fumes (released from the processing of the herbal plant medicinal preparation in the yagya-fire) occurs naturally during yagya. Thus, yagyopathy (yagya-therapy) enables pulmonary administration of the herbal medicines and is therefore expected to be a more efficient mode of healing in case of pulmonary diseases in general and pulmonary tuberculosis in particular.  Considering this and some earlier reports on use of yagya for effective treatment of drug-resistant cases of tuberculosis, thorough scientific study of ancient therapy in the treatment of pulmonary tuberculosis was carried out by Dr. Meenakshi Raghuvanshi as par to her Ph.D.


Results on Chemical Aspects:


Dr. Meenakshi’s thesis presents detailed chemical analysis of the thermal transformation and slow-combustion process of yagya together with the possible reactions and release of important phytochemicals and their anti-bacterial (including anti mycobacterial), immunomodulatory. Studies on other important activities and synergistic and antagonistic effects of the herbs/plant medicines used in special havan samagri used for treatment of pulmonary tuberculosis are also presented her thesis.

Abstract of Research work done by Dr. Ruchi Singh

Detailed analysis of the chemical reactions taking place in yagya is quite complex, as these depend on multiple factors like the nature of substances and their proportions, the temperature  attained during the various stages of heating or combustion at varying levels along the different  layers of different shapes and depth of  the kunda, the arrangement of wood pieces and hence the controlled supply of air, interactions amongst the products formed and the changes on account of synergistic and cascading reactions, etc. Mostly, instead of being burnt, the plant-medicinal preparation undergoes transformation into vapor phase, sublimation or decomposition by gradual heating and spreads along with the volatile substances and gases released by the slow and controlled combustion process in yagya fire (Pandya, 2004). In total, 15 compounds were identified in the yagya smoke extract whereas 13 copmpunds were identified in the non-yagya smoke extract using Nist & Wiley library matches and linear retention index. Only the most abundant compounds with Nist & Wiley library matchings  of 80% or higher and retention times of up to 20 min were considered in the analysis.


Most of the ingredients of Hawan Samagri are known for their medicinal properties and a number of them are used as medicines by practitioners of the Ayurveda and Unani method of treatment. This research attains importance as it has been observed that medicinal smoke emanated from havan sámagri showed very interesting inhibition effects on the aerial bacterial population. From the observations and interpretations it can be concluded that it is not only the fumigation of hawan samagri can reduce the air microbes but the smoke and gases produced as a result of Yagya can cause an overall decrease in the microbial population of air.  Therefore we can arrive at a conclusion that performing Hawan at work places can help in making the environment healthier and more conducive to perform our duties.
