I was told that there is a natural way to tighten your vaginal walls?

Question

I was curious, lol. Something that has to do with inserting a leaf into your v****a. NOT a regular, dry leaf from ANY TREE. I think you are supposed to boil the leaf and then insert it.

This is from the Caribbean Islands.

I was wondering if anyone else has heard of this.

I did not make this up. Laugh if you want to, but I really want to know if this is true or a wives' tale.

Also, please don't suggests that I do kegal exercises, I'm just wondering if this leaf thing is a myth.
