By nature, the lemon has a capacity to remove the negativity and impurities.
There is a secret behind this.
Many places like shop or hotels, the lemon is used to keep at the entrance. They believe that it will remove the negativity or evil eye etc.
Generally the lemon will keep in glass with full of water. If there is any negativity the lemon will get sink inside the glass.
Where the place is good energy it will float on the glass water.
The water should change once in a week.
