Menstrual Blood Drops in a Man’s Drink

Hello, respected Rabbi. I have a friend who puts three drops of urine in a woman’s drink without her knowledge so that she will fall in love with him. Is this true? What does the Torah say about this? Is there a secret in this matter? Also, if a woman puts drops of menstrual blood in a man’s drink and he drinks it, what could happen? Is there a secret in this matter? Thank you very much.
