Patrick relaxed a bit. He didn't mind that one student were working on the Wolfsbane. He had started in his sixth year as well. However, he'd still check because the idea of a classroom trying the Wolfsbane had him itching.
"He's right about that. You shouldn't do it for the points," he said, trying not to quash the boy's enthusiasm. He remembered it all too well.
Patrick laughed. "I know, don't worry. I understand very well. I told you, it was my potion into the experimental division. I understand all too well." He tried to remember back to his Hogwarts days, since most of his research and theory was his own at the moment. "I'm assuming you read Belby's treaty on the subject. There's 2004 revision by Wooldermier that gives you a great grip of why the changes were made. In the end, though, you're better off concentrating on the more practical aspects. Learn all the different steps, how and why they are important to keep in order, the dangerous of not doing so. Also if you want to look at Muggle chemistry, you can see why the use of palladium and cadmium is so important. Both of them closely related to silver in the chemical element list, close enough to affect the werewolf, but not enough to kill him."
