Be very careful in dealing with any spell ingredients with which you are not very familiar. For instance, with wolfsbane, the poison index says " Poisioning from the aconitum plant can occur if it is ingested or handled without gloves. ... Aconitum is also known as monkshood and devil's helmet due to its resemblance to a drawn hood, and is known by some as wolfsbane , because its poison is so toxic that it was once used to kill wolves ."
