The web of a spider is said to have concealed the infant Jesus from Herod's soldiers, and perhaps it is for this reason that cobwebs are regarded as very lucky. In stables and barns they should never be celeared away as they protect the livestock, and it widely believed that destroying a cobweb on purpose will only provoke misfortune. No punishment will be exacted against a person who runs into a spider's web by accident, but this may mean that a friend is about to appear. Similarily, US superstition claims that a girl who finds a cobweb on her door is being advised that her lover is unfaithful, while a cobweb in the kitchen reveals to the attentive observer that there is little love in the house. Laying a cobweb on an open wound will promote the healing process (this may in fact assist in coagulation and kill bacteria). Cobwebs rolled into small 'pills' are sometimes taken as a treatment for asthma, while rubbing a web over a wart and then burning it is said to destroy the wart itself.
