Itching powder refers to a group of powders or powder-like substances that induce itching when applied onto human skin. This is usually done as a practical joke or prank to an unsuspecting victim.
The cause of the irritation can be mechanical, such as products containing ground rose hips.  Another common ingredient is Mucuna pruriens.
