I am a great admirer of traditional soap.
To me traditional soap is a simple blend of oil, usually Olive oil and either Lye (Sodium hydroxide) or Soda Ash (Sodium carbonate), and water - preferably saltwater. With the additions of essential oils such as Laurel. This is made in a cauldron, using the hot process method rather than the cold process method.
I have no idea whether the definition of Castile soap which essentially is the above without the addition of essential oils is either a hot, cold process or both.
Traditional soap is produced around the Mediterranean. France produces Savon de Marseille. They are currently squabbling over the current definition as many manufacturers use modern methods of production using additives and a soap noodle base.

Aleppo and Nablus produce soaps of renown. Aleppo soap is now being produced in France, Jordan, Turkey and Tunisia.
Greece, Turkey, and Tunisia produce traditional soaps. Turkish Laurel soap is called Daphne soap which is similar to Aleppo Laurel soap.
Lebanon produces Baladi soap. Whilst Al Ghar soap is the term used across the Arab Middle East for Laurel traditional soap, including Aleppo and Baladi.
Jordan is producing soaps inspired by either the Aleppo and Nablus method due to the displacement of the soapmakers or family tradition.
Although triple milled soaps are great, they are a more refined soap with exquisite scents. Traditional soap maybe used for hand and face washing, bathing and showering, as a shampoo, as a washing detergent for clothes or as household cleaner. Which your great grandmother probably did.
