Is the traditional method of treatment in Algeria, performed by ordinary people using herbs or simple methods, permissible according to Sharia?

There is no harm in using beneficial methods of treatment proven by experience, as long as they do not cause harm and are not prohibited by Sharia. One must beware of charlatans who claim to heal with the Quran while engaging in magic or seeking assistance from jinn, especially if their methods are only effective through their mediation, which often indicates sorcery.
