The Ancient Secrets of Shilajit: Nature’s Super Supplement
Shilajit is one of the oddest things people take every morning. It's a thick, black, sticky resin that seeps out of cracks in mountain rock. It's been collected by hand for thousands of years. And most people in the UK had never heard of it until a few years ago.
This post covers where it actually comes from, how it forms, and the part it played in the old Ayurvedic texts. If you just want to see what the real thing looks like, here's our Himalayan shilajit resin.
What is shilajit?
Shilajit is a natural resin found in high mountain ranges. It's dark brown to black, tacky like warm toffee, and has a strong earthy smell.
It isn't a plant and it isn't a mineral in the way most people think of minerals. It's somewhere in between. It's mostly made of organic compounds called humic substances, the biggest one being fulvic acid, along with naturally occurring minerals picked up from the rock around it.
You'll find it under different names depending on where you are:
- Shilajit or shilajatu in India and Nepal
- Salajeet in Pakistan
- Mumijo or mumie in Russia and Central Asia
- Brag-zhun in Tibet
Same substance, different mountains, different languages.
How does shilajit form?
This is the bit that surprises people. Shilajit takes centuries to make, and nobody makes it.
It starts with plant matter. Mosses, lichens and small mountain plants get trapped between layers of rock. Over a very long time, that plant material breaks down. The cold, the pressure of the rock and the slow work of microbes turn it into a dense, dark, tar-like mass.
Then, in the warmer months, it starts to move. As the rock heats up in the summer sun, the resin softens and seeps out of cracks in the cliff face. That's when it's collected.
A few things follow from this:
- It only forms in certain places. You need high altitude, the right rock, the right plant life and huge amounts of time. That's why it comes from a handful of mountain ranges: the Himalayas, the Altai, the Caucasus and the Hindu Kush.
- It can't be farmed. There's no way to grow more of it. What's on the mountain is what there is.
- Raw shilajit isn't ready to eat. Straight off the rock it's mixed with grit, stone and other debris. It has to be cleaned before it goes anywhere near a jar.
Our resin comes from the Nepal Himalayas, harvested above 16,000ft and sun dried. If you want the full story from cliff face to your door, we've written it up in The Journey of Shilajit: From Himalayas to Your Home.
Where does the name come from?
The name comes from Sanskrit, the old language of India's classical texts. "Shila" means rock. The texts call it shilajatu, and it's usually translated as "conqueror of mountains" or "rock-born".
Either way, the name tells you what the old writers noticed first. This was something that came out of solid rock, high up, in places most people never went.
Shilajit in the ancient Ayurvedic texts
Ayurveda is the traditional system of medicine from India. Its founding texts were written down roughly 2,000 years ago, though the knowledge in them is older.
Two of those texts mention shilajit by name: the Charaka Samhita and the Sushruta Samhita. These are the two books Ayurvedic practitioners still treat as the foundations of the whole system.
A few things stand out in how they wrote about it:
1. They sorted it into types
The Charaka Samhita describes four kinds of shilajit, named after metals: gold, silver, copper and iron. The dark, iron type was the one the texts rated most highly. It's also the closest match to the black Himalayan resin that's sold today.
2. They grouped it with rasayanas
Rasayana is a category in Ayurveda for the preparations the old physicians held in the highest regard. The word is often translated as "rejuvenation". Shilajit was placed in this group, which is why it shows up so often in later Ayurvedic writing.
Ancient healers used shilajit to promote longevity and vitality. That's the reputation it carried down the centuries, and it's a big part of why people are still curious about it today.
3. They insisted it be cleaned first
This is the part that's still relevant today. The old texts were clear that raw shilajit had to be purified before use. They describe dissolving it, straining out the debris and drying it again. One traditional method, known as surya tapi, uses the heat of the sun to dry it slowly.
So the people who wrote about shilajit 2,000 years ago were already worried about quality. They knew raw resin straight off the rock wasn't the same as clean, prepared resin. That concern hasn't gone away. It's just moved from the physician's workshop to the lab.
We go deeper into all of this in Shilajit and Ayurvedic Medicine: A Timeless Partnership, and the wider timeline is in our History of Shilajit.
Why it mattered to mountain communities
For the people living in these ranges, shilajit was never an exotic import. It was local. Collecting it was a seasonal job, passed down through families, and it meant climbing to places that took real skill and nerve to reach.
That's still largely how it works. The harvesters know which cliffs produce it, when it starts to flow, and how to get to it. It's slow, physical work, and it can't be scaled up the way a factory product can.
From ancient remedy to modern jar
Today shilajit has gone global. That's mostly good news, but it's brought problems the old texts never had to deal with.
There's a lot of product out there now. Some of it is real Himalayan resin. Some of it is cut with fillers, sold as a powder with little or no shilajit in it, or comes with no testing at all. The ancient writers worried about impurities from the mountain. Today's buyer has to worry about what happened after it left the mountain too.
The modern answer is independent lab testing. Every batch of our resin is tested by Huson and Hardwick, part of Alex Stewart Agriculture, an ISO 17025 accredited lab in Liverpool. Our February 2026 batch came back at 73.8% fulvic acid and 88.5% total humic substances, with heavy metals within limits and no E. coli, salmonella or pesticides detected. You can see the full lab results or open the complete certificate (PDF).

We've been selling shilajit in the UK since 2020, and we've sent out over 50,000 jars in that time.
FAQ
Is shilajit a mineral or a plant?
Neither, really. It forms from plant matter that's broken down over centuries inside rock. It's mostly organic compounds like fulvic acid, plus minerals from the surrounding rock.
How old is shilajit?
The resin itself takes centuries to form. People have been collecting it for thousands of years, and it's written about in Ayurvedic texts that are around 2,000 years old.
Where does the best shilajit come from?
The old texts rated the dark, iron type most highly, and that's what Himalayan resin is. More important than origin alone is whether it's been properly cleaned and independently tested. Always ask to see a lab certificate.
Why is shilajit sold as a resin?
Resin is the closest form to how it comes off the mountain, once it's been cleaned. It's easy to check: real resin softens when warm, hardens when cold and dissolves fully in warm water. Our guide on how to take shilajit every day shows you how to use it.
Can anyone take shilajit?
If you're pregnant, breastfeeding, under 18, taking medication or have a medical condition, check with your GP first.
