Significance of Homam or Havan
Havan has been found an effective method to reduce the FUNGAL load in small office or room. As per the experiments conducted the havan fire smoke has the potency to kill fungi like Aspergillus, Penicillium, Curvuleria and cladosporium etc. (Earth environmental science) in June 2007 in Acrobiolagia A Journal published in NETHERLAND. The oxidation of hydrocarbons in (ghee and oils found in dry fruits) produce formic acid and acetic acid (vinegar) used to preserve food material.
Havan smoke is like inhalation therapy derived from AYURVEDA and as described above it relaxes the mind and heals the body and has positive effects spiritually too because of the holy verses (mantras) chanted during the havan.
