Picking and eating scabs is a disorder that falls under the heading of excoriation or dermatillomania, Wikipedia explains. Those with this order pick ritualistically and obsessively at their skin, usually at a place where there is a blemish or a scab.

Trichotillomania Learning Center says that skin picking can be symptomatic of certain health problems, such as autoimmune problems, psychosis and obsessive-compulsive, developmental or substance abuse disorders. Although it is still a mystery why exactly some people have this problem, it is often triggered by a disease or injury that results in a healing wound that can cause the person to pick at it.
