[HP] Polyjuice Potion Is Extremely Dangerous!

The product of imagination (sweet!) How dangerous is something like Polyjuice Potion? Lavender said she had a say. "It tastes so bad that it makes you retch, it can make you become someone else, and it can make you fall in love with the wrong person." Note: 1. Halfway through writing, I thought about Moody and realized that it was completely trivial. 2. But how come dangerous things like Polyjuice Potion and Love Potion are not only not banned but are also included in Hogwarts textbooks! 3. The cover (I really like this picture) comes from the Internet and has been infringed and deleted. 4. Not the Jacob in FB. 5.
