Siyaar Singee or jackal's horn or hood is the only item in the world which made the scientists shocked for not having any scientific reason for the growth of hair in a dead object. In Tantra this is used to protect the dwelling place from all evils and black magic. in Hindee Siyaar means jackal and Singee means horn. a jackal normally has no horn but when it hoots facing downwards, a small bunch of hair with a horn emerging from its body at the forehead. this is taken for and is called Siyaar Singee. it is always kept in vermillion (Sindoor), and its hair grows automatically. in the original Siyaar Singee, the color of the hair on the day it is plucked out of jackal is one and the new hair grown (extension of the same hair) would be in another colour which is clearly visible. this is the clear distinction to identify a fake and a real one. any place where this is kept, all ghosts, spiritis, devils, evils and negative forces just flee and run away. i have done exorcism to several houses using this holy item. suppose a house is haunted by devils and is uninhabited, you just keep this in that house, do a Havan (holy fire) and then the house is free of all evils and ready for occupation. since this is a very rare product with the most miraculous feature of hair growing on its own, it has become priceless. also the hair on the Siyaar Singee gets combed naturally on its own in a particular style.

There was another reason why this jackal's horn is famous in the west. according to Christian belief (as written in the Bible) jackal is the mother of devil and hence any native having jackal's horn is not haunted by the devils.
