Why I Put a Heart Herb in My Kidney Formula

We don't think about our kidneys very often.

They're just quietly there, filtering our blood, helping remove waste, balancing fluids and electrolytes, and doing an enormous amount of work every single day without asking for much attention.

Until, of course, something gets our attention.

Kidney stones. Urinary discomfort. Changes in urinary function. Suddenly those two relatively small organs become very interesting.

Years ago, as I was building out my own formulas for Barlow Herbal, I realized I had created blends to support so many different organs and systems in the body, the brain, lungs, liver and others, but I hadn't created anything specifically for the kidneys.

That needed to change.

I also felt like a good kidney and urinary formula belonged in a home herbal apothecary. Not only for those times when something is going on, but because I believe so strongly in supporting the body before it's asking loudly for our attention.

So I started thinking about what I actually wanted a kidney formula to do.
Urinary flow was certainly part of it, but that wasn't enough for me.

I wanted to think about circulation and the enormous amount of blood moving through the kidneys. I wanted soothing support for the urinary tract.
I wanted to think about elimination and the body's bigger drainage systems.
And I wanted nourishment.

In other words, I wasn't looking for seven herbs that all did the same thing.
I wanted plants that approached kidney and urinary health from different directions.

That's how I ended up with Hawthorn Leaf, Corn Silk, Cranberry, Nettle Seeds, Parsley, Red Clover and Moringa.
And there are three herbs in this formula I especially love talking about because they're probably not the three most people would expect.

Let's start with Hawthorn.
Most people hear Hawthorn and immediately think of the heart.
And they're right. Hawthorn has a wonderful history as a cardiovascular herb.
So why did I put it in Kidney Cleanse?
Because I wasn't only thinking about urine. I was thinking about blood.
The kidneys are incredibly vascular organs. Blood is constantly flowing through them to be filtered, so circulation is part of the kidney conversation too.

Hawthorn brings that circulatory piece into Kidney Cleanse. Its leaves contain flavonoids and other polyphenols that have made this plant such an important part of traditional cardiovascular herbalism.
People see Hawthorn and think heart. I see Hawthorn and think circulation.
And that made perfect sense to me in a formula for two organs that spend their days filtering blood.

Then there's Corn Silk.
Yes, I'm talking about those silky threads you pull off an ear of corn and probably throw in the garbage.  Herbalists look at them very differently.
Corn Silk has a long traditional relationship with the kidneys, bladder and urinary tract. What I especially like about it is that it's traditionally considered both a soothing urinary herb and a gentle supporter of urinary flow.
I love that combination.
Supporting movement is one thing. Supporting the tissues involved in that movement is another.
Corn Silk gave me both.

And I love that something so ordinary, something most of us have thrown away countless times, has this whole other history as an herbal medicine.
That's one of my favorite things about plants. Once you start learning about them, you realize medicine has been hiding in plain sight all around us.

Then there's Nettle Seed. Notice I said seed. Not Nettle Leaf.
A lot of people know Nettle Leaf. It's a wonderful nutritive herb with its own long relationship with the urinary system.
But I specifically chose Nettle Seed for Kidney Cleanse.
The seeds have developed a particularly interesting reputation among herbalists as a deeper kidney and restorative herb.
And that distinction mattered to me.
I didn't only want herbs that encouraged movement through the kidneys and urinary tract. I wanted an herb that made me think about supporting the kidneys themselves.

That's a very different formulation question.
And it really gets to the heart of what I was trying to do with Kidney Cleanse.
Filter. Flow. Soothe. Nourish.

The other four herbs help complete that picture.

Cranberry brings its very specific relationship with the urinary tract. Its A-type proanthocyanidins have been studied for their ability to interfere with the adhesion of certain bacteria to urinary tract surfaces. So Cranberry brings a completely different kind of plant chemistry to the formula.

Parsley is one of those plants people think belongs on the side of a dinner plate, but herbalists have known it for generations as a traditional urinary herb. It helps bring the movement and flow piece I wanted.

Red Clover widens the conversation even further. Traditionally it's considered an alterative, one of those wonderful old herbal words describing plants used to support elimination and the body's internal terrain. It reminds me that the kidneys aren't working in isolation. Skin, lymph, circulation, liver, kidneys and bowels are all part of the body's bigger elimination picture.

And Moringa brings nourishment.
That was important to me too. I didn't want every herb in the formula focused on movement and elimination. Moringa brings broader nutritive and antioxidant plant chemistry and helps balance the formula.

That's why these seven plants ended up together.
Hawthorn Leaf, Corn Silk, Cranberry, Nettle Seeds, Parsley, Red Clover and Moringa.

I wasn't looking for seven plants that simply had "kidney herb" written next to them in an herbal book.
I was thinking about what the kidneys actually do and asking what kinds of herbal support made sense around that work.
Circulation, urinary flow, soothing, elimination, urinary tract support and nourishment.

Or, put much more simply:
Filter. Flow. Soothe. Nourish.

That's the thinking behind Kidney Cleanse.
And I think it deserves a place in the home herbal apothecary right alongside the herbs and formulas we keep around for the liver, lungs, immune system, digestion and brain.

Because those two quiet little organs are doing an incredible amount of work for us every single day.

I think they're worth taking care of before they have to ask for our attention.

Stay grounded and growing!
