There are many examples of this but one that I know is that, such as in Indonesia. In the past people use turmeric as a scrub and I was taught about that by my mother.
The use of turmeric as a scrub and jicama for facial masks is quite fascinating. That is quite an awesome traditional knowledge passed down through your mom.
There are many traditional ingredients and face masks here and it's nice that it's passed down from one to another. If I were to have a kid one day, I'd definitely tell them about it too.
