Throughout history incense is used and viewed as purifying cleansing and so for a reason!
"Incense has antibacterial properties and can kill many types of germs and clear the environment. It is very useful to prevent infectious germs and keep the environment clean and germ-free."
"Some incense has been found to have special antibacterial properties, which enable them to naturally purify the air and surfaces in a room. A recent study conducted in a Chinese hospital showed that certain fragrances (particularly ones with a higher concentration of naturally antibacterial resins such as frankincense and myrrh) were just as effective at sterilizing a room as steam cleaning. Pure air also has additional health benefits, in a similar way to eating healthy food. Incense made with actual resin, like our natural black frankincense incense, are the best for this."
"CONCLUSIONS: The antimicrobial properties of essential oil derived from frankincense, a compound with well-known traditional use, showed that it possesses a clear potential as a natural antimicrobial agent. Moreover, the results suggest possible application of B. carteri EO vapour and incense fume as occasional air purifiers in sacral ambients, apart from daily church rituals."
