Sesame oil is the most commonly used oil in traditional cooking. It likely was a staple.

A family of four needs about half a days with of cooking oil to have a bath with oil.

Could you put some mL estimates on those two measures? It would seem to me that I'd need 50x as much oil to bathe in than I'd need to cook for a half a day, making me think I'm clearly thinking about either the bathing or the cooking quite a bit wrongly.

I’d imagine this is talking about more of a sponge bath situation than an immersion situation.
