Dr. Hafkine (Poland) remarks on Ghee (Clarified Butter) used in Agnihotra
Ghee (ghṛta) is the essential offering to Agni (fire) in all the sacrifices.
As the Ghee is burnt in the fire its smoke and fragrance cover the entire environment and the medicinal values embedded in it go to all.
It purifies the environment. Experimental studies show that the incidence of physical ailments, sickness, and disease is reduced in the houses, where the Yajña (Agnihotra) is regularly performed because it creates a pure, nutritional, and medicinal atmosphere.
The observation of some distinguished scientists is noteworthy in this regard.
Dr. Hafkine has mentioned that ---
“mixing ghee and sugar and burning them creates smoke which kills the germs of certain diseases and secretion takes place from some glands related to the wind-pipe, which fill our heart and mind with pleasure.”
Sugars present in Haviṣhya have great power to purify the atmosphere. It kills the germs of T.B., measles, smallpox, and cow-pox
