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.
Who should avoid Śilājatu?
- Do not use if you are pregnant, breastfeeding, or trying to get pregnant, because safety has not been tested.
- Do not use if you cannot confirm the product is purified and lab-tested for lead, arsenic and mercury; raw rock pitch must never be eaten.
- Do not use if you have haemochromatosis (a disease that makes the body store too much iron) or any other iron overload problem.
- Do not use if you have thalassaemia or sickle cell disease, or if you have regular blood transfusions, as iron builds up in these conditions.
- Do not use if you take iron pills, unless a doctor has checked your iron levels first.
- Do not use if you have gout (a painful joint disease caused by too much uric acid).
- Do not use if you have kidney disease or have had kidney stones, unless your doctor agrees.
- Do not use if you are under 18 years old.
- Do not use if you have a fever or an active infection; wait until you are well.
- Do not use if you are taking a blood thinner, a diabetes medicine or a blood pressure medicine without asking your doctor first.
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.
