Nature's Hand Wash? An Investigation into Horse Chestnut

Run out of hand sanitiser? Caught short out on a walk and don't have soap? Camping, and have dirty hands? If you have a horse chestnut anywhere near you, you might be in luck. This was the case when we were walking a few days ago and, having touched many fences and stiles, we were a little reluctant to begin our picnic lunch of crackers, hummous and some delicious Somerset cheese.

I can't say using horse chestnuts as soap was my idea - we had actually seen it on a Youtube by UK bushcrafter Haze - my husband has a bit of a boy crush on him. One simply tears horsechestnut leaves, adds water and lathers. That we did, whist watched by a curious robin who was after our Jacob's Crackers. A vigorous scrub brings a few tiny bubbles, and left my hands nice and smooth. It wasn't til I got home that I started investigating horse chestnut a little further. Was there any truth to the horse chestnut hand sanitiser recipe, or did I just scrub my hands with a handful of leaves for no reason?

There is a magnificent horse chestnut tree just outside our driveway. For the last month, we've watched it go from a bare boned skeloton to an almost fluorescent green giant. Squirrels dart up the trunk. I've never had horse chestnut on my tree radar - in Australia, we don't really grow up with conkers, as kids here in the UK used to, using them for games. On this trip, though, I've been drawn to them - they certainly are beautiful. Do yourself a favour and watch this video of one over the course of a year:

Horse chestnut for a general soap is quite common, I discover. It contains saponins - particularly the seed itself, which if crushed and lathered with water, creates quite the foam. Add a few essential oils, and you have a zero waste, sustainable clothes detergent, and can certainly scrub away at dirt and grease on your hands if you're out in the wild. If you're using the seed, it's simply a matter of smashing them up and adding water. And for the leafs, the crush and add water thing works a treat, as we can attest. It's also used in home made soaps. I'm told that even cars crushing the seeds in puddles as they drive over them cause a soapy lather on the road!

And the thing about saponins, is that they are detergent-like substances which have anti-bacterial properties.

So maybe washing your hands for two rounds of happy birthday with horse chestnut leaves has something in it after all? Remember, it's not conker season here, nor did we walk with a hammer to break into them, so the leaves had to do.

Horse chestnuts, particularly the seeds, have been used in traditional remedies for anything to do with veins, from swollen ankles to hameorrids. In Germany, it's used in sports medicine, to 'ease pain, bruising and swelling from sprains and other contusions or sports injuries.', according to Mother Earth Magazine., reducing pain and swelling, as well as preventing bruising (something I've always used arnica for). The article continues to add that:

'A recent review of these studies concluded that horse chestnut seed extract is safe and effective for decreasing symptoms of CVI, including reducing lower-leg volume (circumference at the calf and ankle), leg pain, itching, fatigue and muscular tension in the legs. Five of these clinical trials compared horse chestnut extract against treatment with a standard drug. The reviewers concluded that horse chestnut extract was superior to placebo and just as effective as the standard (European) treatment. Another trial suggested that horse chestnut extract is as effective as compression stockings.'

Another study suggests that:

Extracts from A. hippocastanum, and in particular, those based on horse chestnut seeds, contain saponins, known collectively as aescin, which have a gentle soapy feel, and are potent anti-inflammatory compounds. The results indicated that each the crude extracts of the leaf, seed, seed coat and fruit capsule extracts of A. hippocastanum(horse-chestnut) exhibited more or less pronounced antibacterial and antifungal potencies in the case of both gram-positive and gram-negative bacteria and fungus.

So, at a push, if you're stuck, I'd say grab a handful of horsechestnut leaves and scrub away. Sure, next time I'm packing my hand sanitisier, but at least if I forget, I have a back up.

Love this, bookmarked! :) I've been out foraging in the woods and fields .. but I've never heard of horse chestnuts/leaves used in such a way. You learn something new every day, thank you for the lesson. :)

Have you been absolutely gorging on wild garlic like the best of us, @perceputalflaws? There's a really nice youtuber called Haze, he's from Yorkshire. He's the one I first heard tell of it. Bushcrafter. Give it a go next time you're out - really give it a lather. You'll be impressed! And they looks so beautiful this time of year, don't they?

Good information, I will look for this tree. It is attractive as an extra bonus.

I use comfrey in a tincture for bruising.

Be Blessed, I love the Natural Medicine tag.


comfrey is great for that, isn't it? @nateonsteemit makes a good comfrey salve - there's a crosspost of it in the Nat Med community if you want to check it out. Lots of wild comfrey around here too! Hope you are well.

I make a comfrey tincture myself, and I posted the method on steemit. I will go to @nateonsteemit and see what he makes, thanks!


What an amazing tree and so pretty as well, I've not seen any here in our gardens but believe they grow in the Cape. I wish we had them here as I'd love to try it for its anti inflammatory properties. It's fascinating how nature provides cures and how fabulous that we can learn about it here on Hive!
Loved that short video too, thanks for sharing.

No worries - amazing huh? If you have them on the cape, do go collect some come conker season, and see how they lather!

Horse chestnut = conkers? I never made that connection, but then my knowledge of nature is crap😅

There you go - stand knowledgeable now! And next time you go walking, look for them, and try the leaf hand wash! You'll wow your walking companion!

So many of our trees contain saponins!! Surprisingly! Funnily enough just yesterday I was looking at a young tree I planted in my Thai garden - locally it's called "Sabu Dam" - means "black soap". My guess is it's a variety of Asian chestnut. I've been growing the tree to experiment with making natural, non-soap facial wash. LOL. Let's just say it's a long game project. LOL.

Lovely post, my dear. So glad you are finding natural medicine wherever you are. Mother Earth is truly amazing that way, no?

Hoping France and Portugal in June might work for you... and sending love. x

We hope so too, though part of me just wants to go to the creature comforts of home! Fingers crossed. Ever in hope.

oooh - an asian chestnut!!!! Really interesting. I know they make shampoos out of horse chestnut, so that makes sense.

Mother nature is ENDLESSLY incredible. thanks for your beautiful comments xx

I didn't know this about horse chestnuts. Hmmmm.... Wish I had more room for trees.

Fascinating, right? You might have one in your local area? They are gorgeous trees, but do grow quite large.

This is why I love this community. There's always something new and interesting to learn everyday. This is the first time I will be coming across the plant known as horse chestnut, I will have to find out more about its botanical characteristics. Between, I'm not sure it grows around here in the tropics but that will be found out during my research. Nature has solution to virtually all our problems, we just need to search enough.

I know @gentleshaid - isn't it amazing?? I believe that if there's anything that ails you, you'll find a solution right on your doorstep!!!! If you can't find horse chestnut, look for a local plant with saponins and see what you find!

I am so pleased you found our community - really. It warms my heart you're part of it. xx

You can bet I'm already researching local plants with high saponing contents in the absence of horse chestnut. If I discover anything interesting, I might make a post post about it.

I think you will absolutely have to! Even if it doesn't lead anywhere, it's nice to read about people's research and experiments on Natural medicine.
