Medical-type swabs are often used to take microbiological cultures. The swabs are rubbed onto or into the infected area, then wiped across the culture medium, such as an agar plate, where bacteria from the swab may grow. They are also used to take DNA samples, most commonly by scraping cells from the inner cheek in the case of humans. They can be used to apply medicines to a targeted area, to selectively remove substances from a targeted area, or to apply cleaning substances like Betadine. They are also used as an applicator for various cosmetics, ointments, and other substances. You should avoid using loose cotton wool on open cuts and grazes, whether it’s in the form of a cotton ball or cotton pad.

Cotton wool roll can be used as an absorbent material to soak up excess fluid from a wound.

Your ear has a natural cleaning system that works kind of like a conveyor belt, sweeping excess wax out regularly. If you push wax deeper inside by using a cotton bud, it prevents the wax from being swept out and can potentially lead to a dangerous build-up of compacted ear wax.

Feature papers represent the most advanced research with significant potential for high impact in the field. A Feature The use of cotton swabs in the ear canal has no associated medical benefits and poses definite medical risks. [11] [12] [13] [14] Cerumen (ear wax) is a naturally occurring, normally extruded, product of the external auditory canal that protects the skin inside the ear, serves beneficial lubrication and cleaning functions, and provides some protection from bacteria, fungi, insects, and water.
