Salajeet (Shilajit): Fakes, Home Purity Checks and Heavy Metals
The tin says “pure Gilgit salajeet”. It cost you 1,500 rupees for 20 grams, it is black and sticky, and it smells vaguely of tar. Any of that could be true salajeet. All of it could also be boiled molasses with charcoal, or worse, and the tin will not tell you which.
Before you buy
- Salajeet (shilajit) is: a dark, tar-like substance that seeps from rock in high mountains, formed over centuries from decayed plant matter and minerals
- Where it comes from here: Gilgit-Baltistan, Chitral and the Karakoram; also Nepal, Ladakh and Central Asia
- Sold as: raw lumps, purified resin, dried powder, capsules
- Why fakes are common: real supply is small, demand is large, and the genuine article is easy to imitate by eye
- The two worries: fakes made from anything dark and sticky, and genuine raw salajeet carrying lead, arsenic or mould
- Honest expectation: a traditional winter tonic; no evidence of dramatic effects on stamina, sugar or weight

What salajeet actually is
Salajeet is not a plant, not a mineral and not an animal product. It is humus: the slow decay of mosses, lichens and other plant matter compressed in rock over very long periods, which in summer heat softens and oozes out of cliff faces above roughly 3,000 metres. Collectors scrape it off, and the raw material comes with rock grit, sand, dead insects and whatever else was on the cliff. Purification traditionally means dissolving it in water, filtering out the debris, and drying the liquid back down to a resin in the sun or over low heat.
The dark colour and the sticky, slightly shiny texture come from fulvic and humic acids, the same family of compounds that make good compost dark. That is the honest chemistry: mineral-rich decayed plant matter. It is interesting. It is not magic.
Unani texts class salajeet as hot and dry and use it as a winter strengthener for weakness after illness, aching joints, and “kamzori” of every sort. Ayurveda calls it a rasayana and holds that it carries the properties of other herbs deeper into the body. The traditional intake was tiny: a piece the size of a grain of rice to a small pea, softened in a spoon of warm milk or water, taken in the morning through the cold months and stopped in summer, when its heating nature was thought to be unwelcome. That seasonal restraint is worth copying.
Why fakes are so common
Real salajeet is scraped by hand from remote cliffs, then purified, and the yield is a fraction of what was collected. Meanwhile it sells for stamina, and stamina sells. The gap between supply and demand is filled with things that look right: molasses or jaggery boiled down with charcoal or coal dust, tar mixed with gum, dried fruit paste with black colour, and low-grade salajeet “extended” with any of these. Some sellers also add raw, unpurified lumps that carry mould and the heavy metals present in the rock. None of this shows through a tin.
Simple home purity checks, and their limits
These take five minutes and catch the crudest fakes. They do not prove purity, and a seller who knows the tests can pass them with a good fake.
- Warm hand test. Hold a pea-sized piece (about 0.3 g) in a closed palm for 60 seconds. Genuine resin softens and becomes tacky with body heat. Put it in the fridge for 30 minutes and it should turn hard and glassy, shattering rather than bending when tapped. A fake often stays uniformly gummy in both.
- Dissolving test. Drop a pea-sized piece into 100 ml of warm water (about 50°C) in a clear glass and stir for 2 minutes. Genuine salajeet dissolves fully into a clear golden-brown to reddish-black liquid with no grit, no floating oil and no sludge at the bottom. Sand, charcoal or gum settles out or clouds the water; a molasses fake dissolves but smells sweet and tastes sweet.
- Taste and smell. Real salajeet is bitter, earthy and slightly smoky, never sweet. A sweet or fruity note means sugar-based filler.
- Flame test, with care. Place a rice-grain amount on a spoon and hold a lighter under it for 10 seconds, outdoors or by an open window. Genuine resin bubbles, swells and chars to ash without catching a lasting flame. Something that catches and burns like a candle is likely tar, wax or resin gum. Do this over a plate, not a carpet.
- Read the paper, if there is one. Reputable sellers offer a laboratory certificate showing heavy metals tested by a named lab, with lead, arsenic, mercury and cadmium reported in parts per million. Look for the lab’s name, a date within the last year, and a batch number that matches the tin. A photo of a certificate on Instagram with no batch number is decoration.
The limits are real. A skilled fake made from low-grade salajeet extended with molasses will soften, dissolve and taste roughly right. Home tests cannot detect lead or arsenic at all. The only thing that can is a laboratory, which is why the certificate matters more than the flame.
The heavy-metal question, stated plainly
Salajeet comes out of rock, and rock carries metals. Raw, unpurified salajeet has repeatedly been found to contain lead and arsenic at levels that matter if taken daily for months. Proper purification removes much of this, but the buyer has no way to know how carefully it was done. Add the possibility of fillers, and the risk sits in the same family as the one we describe in our kushta and heavy metals article: small daily amounts, slow build-up, vague symptoms. Tiredness, stomach pain, constipation and poor concentration are the early signs of lead exposure, and they are also the reasons people buy salajeet. If you have been taking an uncertified product for more than 2 or 3 months, a blood lead test is a sensible, inexpensive check.
Honest expectations
What is fair to expect from a genuine, purified product taken in traditional amounts through winter? Perhaps a modest sense of warmth and wellbeing, the way people feel on a winter tonic they believe in. Some trace minerals, in amounts a normal diet also provides. That is about it. The claims that sell it, doubled stamina, higher testosterone, reversed diabetes, faster weight loss, more hair, are not supported by anything you should bank on, and a product that promises them is telling you something about the seller. If tiredness or sexual weakness is the reason you are buying, the useful next step is a blood test for iron, thyroid, vitamin D, B12 and sugar. Those answers are cheaper than the tin.
Mineral-rich decayed plant matter. Interesting, yes. Magic, no.
Myth: real salajeet is always from Gilgit and always safe
Gilgit-Baltistan produces excellent salajeet and also lends its name to a great deal of sticky black filler. Origin on a label is unverifiable and the region itself has no shortage of unpurified product. Genuine origin and safe purity are two separate questions, and only a lab test answers the second one.
Pregnant and breastfeeding women (no safety data, and heavy metals cross to the baby). Children. Anyone with kidney or liver disease. Anyone with gout or high uric acid: some reports link it to a rise in uric acid, and tradition already rates it hot, so check with a doctor first. Anyone with iron overload (haemochromatosis) or sickle cell disease, because salajeet carries iron. Stop it 2 weeks before any surgery. On blood pressure, diabetes or blood-thinning tablets? Check with your doctor first, since anything that changes appetite, fluid balance or clotting can shift those medicines. Stop and see a doctor for stomach pain, vomiting, a rash, dark urine, yellow eyes, numb feet or unusual tiredness. And regardless of any tonic, a doctor, not a tin, is the answer to pain or pressure in the chest, trouble breathing, blood where it should not be (stool, urine, sputum), weight dropping without a diet, any new lump, a fever past its third day, yellow eyes, a fit, a face or arm suddenly weak or speech suddenly slurred, bleeding while pregnant, and a baby younger than 3 months with any fever.
Before the tin goes in the basket
Ask the seller three questions in writing: Which lab tested this batch for lead and arsenic, and can I see the report with this batch number? Was it purified by water filtration or just dried? What is the net weight of resin, not the tin? A seller who answers all three plainly is rare and worth keeping. One who answers with testimonials has answered anyway.
Salajeet sits in the honest middle of the Unani shelf: a real traditional substance, easy to fake, with a genuine contamination risk and modest realistic benefits. The same clear-eyed approach runs through the whole Unani & Herbal, Decoded series, including our look at ashwagandha, which is often sold alongside it.
Common questions
How is salajeet traditionally taken?
A piece the size of a grain of rice to a small pea, dissolved in a spoon of warm milk or warm water and taken in the morning, in winter only. Capsule products carry their own directions on the pack. Larger amounts do not add benefit and add risk from whatever is in the product besides salajeet.
Resin, powder or capsules: which is safer?
None is automatically safer. Resin is easiest to test at home; powder and capsules are easiest to adulterate invisibly. What makes any of them safer is a lab certificate for that batch from a named laboratory.
Can women take salajeet?
Tradition uses it for both sexes in winter. The cautions are the same: not in pregnancy or breastfeeding, not with kidney, liver, gout or iron-overload conditions, and never from an untested source.
Does it help with diabetes?
Do not take it for that. There is no reliable evidence, it must never replace or change prescribed medicine, and anyone on insulin or sulfonylurea tablets who adds unfamiliar products risks unexpected swings. Talk to your doctor before adding anything.
How should I store it?
In a sealed glass or steel container, out of sunlight, at room temperature. It will be hard in winter and soft in summer; that is normal and is one of the signs it is genuine. Mould on the surface means throw it away.
What does a good lab certificate look like?
A named laboratory, a test date, a batch number that appears on your tin, and numbers for lead, arsenic, mercury and cadmium in parts per million alongside a stated limit. Vague phrases like “tested pure” without figures are not a certificate.
