pica
Let an agent explain pica in general terms, distinguish clinical pica from culturally sanctioned practices such as geophagy, relay assessment and management information from clinical sources, and route personal or child concerns to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain pica in general terms, distinguish clinical pica from culturally sanctioned practices such as geophagy, relay assessment and management information from clinical sources, and route personal or child concerns to clinicians.
An eating disorder in which a person persistently eats non-food substances such as earth, clay, ice, paper, hair or starch for at least a month in a way not appropriate to their developmental level or culture; it occurs in children, in pregnancy and with iron deficiency, autism and intellectual disability, and can cause poisoning, obstruction and infection.

It can be explain the condition and its associations; distinguish clinical pica from cultural practices; relay assessment and management information; route concerns to clinicians.
