You might see lemon and chili hanging on doors of shops, homes, etc and also in vehicles but why are people practicing this thing from old times?
So do they really believe that it will keep away evils and black magic?
The scientific reason behind hanging lemon and chili on entrance –
Long ago, the technology was not that advanced so pesticides were not available. So, our Ancestors invented this insecticide from Lemon and Chili. They used to put the lemon and chili on doors of their shops or home to keep away the mosquitoes and insects because they used to live in the homes made up of mud and stones.
Lemon and Chili are very rich in vitamin C. So when the lemon and chili were pierced by a cotton thread, the fluid ( acid from the lemon ) stick all over the thread and the smell of it get spread into the surrounding environment with the help of air. This smell helps to repeal the mosquito & fly to enter into shops and homes and in the same way, Chili too is remedial as it acts as germ-killer when hung outside.
