The rules are different in every state, and the sources are scattered. This directory covers all 50 states and Washington, D.C., and points you to the board's own rules rather than replacing them.
What a state page holds
Each state starts with its responsible authority, then lists each license type separately with its own fields, and sections for getting your first license, herbal medicine, keeping the license active, rules after you open, and official resources. Herbal authority is its own section, separating recommending herbs from dispensing, compounding or selling them, because states treat those differently. A state's page shows when its sources were last opened. Each state has its own address, covered in Licensing page per state.
Every claim carries a label
Source checked means the claim was read against a named official page. Needs review means something was found but could not be fully confirmed, or sources disagree. Help wanted means it has not been confirmed from an official source yet. None of these says a rule does not exist: for Oklahoma and South Dakota the guide found no licensing act, only introduced bills, and says that is not proof practice is unregulated or prohibited. A coverage bar on each page counts its fields as source checked, needing review or help wanted, and the guide says plainly that a separate verification pass is still under way.
Corrections and missing states
Each state page has a correction form that carries the state and asks for an issue type, an explanation, an official source URL and an optional reply email. It warns against sending patient or confidential information. A state with no research yet offers a request instead. Reports go to a review queue; nothing on the page changes automatically.
Opening a practice involves more than a license, so the guide links to the opening checklist and, for training, the schools directory.
