Fourwing saltbush as a salt source?
I was reading up on fourwing saltbush, as it's pretty common around here. It's edible (but not very tasty, in my experience), and has other uses, for example, its ashes can be used as a leavening and nixtamalizing agent.

It's known to thrive in salty, alkaline soils. It's my understanding that it absorbs the salts into its leaves, and as the leaves fall off, the salt is removed.
So I'm wondering if you were out in the desert, sweating like crazy, could you eat the leaves to help boost your electrolytes?
