What is Śilājatu? Śilājatu is a sticky, tar-like goo that seeps out of rocks in high mountains. In Ayurveda it is used as a tonic. People take it for low energy, aging, and fertility problems. You may see it sold as shilajit or mineral pitch. Its Latin name is Asphaltum punjabinum. In Ayurveda it counts as a single drug, not a blend of herbs. Now the proof. Human studies are few, small and weak, so we cannot say it works. Long use in a tradition is not proof of effect, and that holds for every part of this page. How does Śilājatu work? No one has shown how it works in the body. The main idea is that it acts as an antioxidant (something that mops up unstable bits called free radicals, which can harm cells). Śilājatu holds humic and fulvic acids. These form over ages as plants break down in rock. Lab tests show they can bind metals and soak up free radicals in a dish. Animal work hints at effects on how cells make energy, and on iron in the blood. Animal results often do not hold true in people. Treat all of this as a guess, not a fact. What forms does Śilājatu come in? The most common form is a black, sticky resin sold in a jar. You dissolve a pea-sized dab in warm water or milk. It also comes as a dried powder, as capsules, and as liquid drops. Capsules are easier to dose but hide what is inside. Ayurveda uses śuddha śilājatu. This is pitch that has been washed and cooked to take out grit, rock and some metals. Raw rock pitch is not safe to eat. Look for a brand that shows lab test results for lead, arsenic and mercury. Where it comes from: Śilājatu appears in old Ayurvedic texts such as the Charaka Samhita, written about 2,000 years ago. It is named there as a rasayana, a tonic meant to restore strength. It is gathered in the Himalaya, the Altai and other high ranges. Tibetan, Unani and Central Asian healers use much the same material under names like mumijo.

Helps

What does Śilājatu help with? Low energy and tiredness: This is the most common reason people take it. A few small human studies have looked at tiredness, but they were short and poorly run. There is not enough good proof to say it helps. Low testosterone and male fertility problems: Ayurveda has long used it for sexual weakness in men. Small modern studies have measured sperm counts and hormone levels, but they were tiny and some were paid for by sellers. The results are not strong enough to rely on. Sports recovery and muscle strength: Some small trials have tested it in gym users for strength and recovery. The groups were small and the effects were mixed. No firm answer yet. Altitude sickness: Mountain healers have long given it to people who feel ill at height. We found no solid human trial that tests this. Do not use it in place of coming down the mountain or getting oxygen. General tonic use in aging: Classic texts call it a rasayana, a tonic said to slow the wear of age. This is a traditional claim about the whole body, not a claim any trial has tested. Modern evidence for it is missing.

When should you see a doctor?

See a doctor soon if you get belly pain, feel sick, or feel unusually weak while taking it. Also see a doctor if you get joint pain and swelling, which can be gout.

Get urgent care the same day if you have dark urine, yellow skin or eyes, a fast or odd heartbeat, or any trouble breathing. Stop the product and take the jar with you.

If you have taken raw or untested pitch for weeks, ask your doctor about a blood test for lead and iron.
