In the wake of the many wildfires that repeatedly torment our planet in the summer seasons, frequently reported so in the media from Canada, the US, Australia and Southern Europe, it becomes obvious that quite often what ignites such fires is malicious arson.
Where there are no commercial interests driving such arson, it is likely to be a mental derangement. Who is the pyromaniac that has the impulse to start such horrific destruction? The repertories have only few remedies in the specific rubric looking at the desire of setting something on fire.
Murphy’s repertory  and Schroyens’s Synthesis  have listed the following remedies in the rubric “Mind – Fire – set things on fire; wants to”:
Alco., Ant.t.. – 
Alco., Ant.t., Bell., Carc., Hep., Hyosc., Phos., Staph., Stram.. –
