According to a study published in the respected Australia Medical Journal, some people are more prone to exhibit “werewolf” tendencies during a full moon.

The findings from the 11-month research at the Calvary Mater Newcastle Hospital could force police and other emergency services to shake-up how and when they deploy staff.

Many in the law and emergency service have already claimed for years there is a correlation between a full moon and more violent episodes, however, many police have disregarded anecdotal evidence as only a coincidence.

The hospital’s clinical research nurse in toxicology Leonie Calver said the study centred on 91 patients who attended the emergency department, displaying “violent and acute behavioral disturbance” between August 2008 and July 2009.

“Of the 91 patients, 21 (23 percent) presented during the full moon double the number for other lunar phases,” Ms Calver said.

Coincidence? Hardly, because “sixty-six percent were under the influence of alcohol and/or recreational drugs and five attacked staff.

“Some of these patients attacked the staff like animals (by) biting, spitting and scratching. One might compare them with the werewolves past, who are said to have also appeared during the full moon.

“It has been reported that the practice of rubbing magic ointment on the skin or inhaling vapour from a magic potion by an alleged werewolf induces metamorphosis.

“Not surprisingly, the main ingredients of these ointments and potions were belladonna and nightshade, both of which can produce delirium, hallucinations and delusion of bodily metamorphosis.”
