Is it permissible, in Islamic law, to seek treatment using inherited traditional methods (such as herbs and placing a grain of wheat in the ear) from ordinary individuals who are not characterized by piety or knowledge, or is it better for a person to treat themselves?

Whatever treatment is proven beneficial, does not cause harm, and is not prohibited by Islamic law, there is no objection to using it. However, one must be cautious of those who claim to heal with the Qur'an but use magic or seek help from jinn, especially if their methods are ineffective without their presence, as this often involves sorcery and charlatanism.
