For sida acuta, in the making of tinctures, the book says to use dried leaf. For teas, powdered leaf.
I do not see cordifolia listed in the index, and I'm not going to dig through the book, I apologize. I don't know how the two compare to one another. I've never stopped to think about
I'm seeing a lot of leaf recommended, without mention of the root, so it's probably safer to assume they're not interchangeable.
Then again, I'm not an herbalist. I couldn't begin to tell you how or why the two differ greatly. It's the same plant. The constituents would have to travel up to the leaves from the roots, right? So, you'd think the benefits would be similar. Though, maybe the leaves' interaction with the environment (sunlight, gas exchange) changes the way those constituents work for medicinal purposes.
I mean, it's all one organism. Though, I guess there's a reason why, maybe a poor example, people kill elephants just for the tusks. Different parts of the same organism have varying levels of significance. My brain does things my liver doesn't. You could apply that to plants, on some level, I suppose.
Sorry, just thinking out loud. Don't mind me.
Really interesting and confusing stuff that my brain's not gonna get into today.
