Unless you are otherwise licensed you should not offer any medical, tax, accounting, financial, or legal advice. Your clients should consult with their accountant, attorney, physician, or financial advisor for advice on your topics. Specific advice on any subject is considered professional advice. For example, generally stating that there are tax deductions available to individuals who own businesses is general advice a lay person can discuss. On the other hand, conducting a detailed conversation with a client about a pending legal issue, and then giving them instructions on how to resolve the issue they face is professional advice. Telling a client that your product will cure, eliminate, or eradicate any type of medical condition is strictly prohibited.
