This plant is known because of its antibacterial properties. It is believed to be an ally for the disappearance of a lump behind the ear. In fact, several studies indicate that several of its components (such as ethanol or methanol) have antimicrobial properties, so they can be useful to alleviate some bacterial diseases such as infections. By applying aloe vera to the area with the lump, the microbes that caused its appearance may no longer have the opportunity to spread.
