Havan for bacteria-free homes: Study

Want to lead a healthy life and free your home from bacteria? Perform `havan` at regular intervals.

Lucknow: Want to lead a healthy life and
free your home from bacteria? Perform `havan` at regular
intervals.
A study carried out by a team of scientists at
National Botanical Research Institute (NBRI) here has claimed
that smoke emitted during havans reduces airborne bacteria to
a large extent, minimising possibility of infectious diseases.

"Burning wood and medicinal herbs, better known as
`havan samagri`(mixture of wood and odoriferous and medicinal
herbs), can effectively reduce pathogens in the air," NBRI`s
senior scientist Chandra Shekhar Nautiyal told reporters.

The study had already been published and accepted by
Science Direct, a journal of ethnopharmacology.

"As described in Rigvedas, saints used to perform
agnihotra-yagnas to purify the environment by sublimating the
havan samgri in fire," he said.

In a bid to study the actual impact of havans, an
indoor study was carried out by the NBRI team including Prof
Nautiyal, Puneet Singh Chauhan and a fellow of Asian
Agri-History Foundation Yeshwant Laxman Nene.

A complex mixture of over five dozen odoriferous and
medical herbs was obtained from Gurukul Kangri Pharmacy in
Haridwar and burnt in an indoor environment to study its
impact on the environment.
"Air sampling before and after performing havan was
done to ascertain its impact on the environment," Prof
Nautiyal said.

"After the experiment it was observed that though
there was was no reduction in the number of bacteria by
burning of wood alone, smoke emanating from herbs led to over
94 per cent reduction in aerial bacteria," he claimed.

"Absence of pathogenic bacteria in the open room even
after 30 days was indicative of the bacterial potential of
the medicinal smoke treatment," he said.
