Cow dung is a very good disinfectant. In the olden days, cow dung was mixed with water and applied in front of houses every day as a disinfectant. Our misplaced sense of cleanliness in modern times has classified cow dung as dirty. Nothing could be further from the truth.
Neem and certain other leaves mixed with cow urine is a very effective pest repellant that has no adverse effect on the environment and human health. Chemical pesticides are highly toxic and have a severely detrimental effect on the environment and human health. Many present-day diseases have their origin in pesticides.
In recent times, agricultural lands destroyed by a tsunami and rendered unfit for agriculture were reclaimed by applying cow dung in large quantities.
In the Bhopal tragedy in which a toxic gas leak at a Union Carbide plant killed 5200 people and left thousands with disabilities, it was reported that the families in two houses only a mile away from the leak were not impacted at all, while the families all around them succumbed to the poison gas. At these two houses, the agnihotra (fire ritual)was performed daily using cow dung cakes and cow ghee.It is well known that the smoke from cow dung cakes has a purificatory effect on the environment.
Research in Russia has proven the disinfectant and anti-pollution qualities of the smoke from Gomaya (cow dung). There is also news that cow dung was used to mitigate the ill effects of the Chernobyl nuclear leak.
The cow plays a key role in protecting our environment; hence, it is our duty to protect the Indian breed of cows.
