Asphaltum punjabianum · Mineral pitch

Also known as: Shilajatu, Mineral Pitch, Asphaltum, Shilajeet

Part used: Purified exudate

Shilajit is not a plant but a mineral exudate that seeps from Himalayan rocks in summer — a blackish-brown resin formed over centuries from compressed plant material. Ayurveda classes it as a Rasayana and uses it for energy, urinary complaints, diabetes and male vitality. Raw shilajit carries heavy metals and must be purified.

Introduction

Shilajit (purified mineral pitch) is a revered Ayurvedic rejuvenator — a mineral-rich exudate that seeps from Himalayan rocks. A powerful Rasayana and Yogavahi, it strengthens, energises and carries other herbs deeper.

Classification

Classed among the great Rasayana and Yogavahi (synergistic) dravyas, purified Shilajit is rich in fulvic acid and minerals. Its pungent-bitter-astringent taste and heating potency clear Kapha, energise and rejuvenate.

Uses & benefits

Shilajit is a mineral exudate used as a Rasayana in weakness, low stamina and in Prameha, and as a Yogavahi that carries other drugs deeper into the tissues. It is used over long courses with milk, and only in the Shodhita (purified) form.

Shilajit for energy and stamina

Its best-known use — a Rasayana taken over weeks for fatigue and low endurance rather than as an immediate stimulant.

Shilajit for urinary complaints

A classical Prameha and Mutraroga drug, and one of its oldest documented indications.

Shilajit for diabetes

Named among the principal Pramehahara drugs in the classical texts, used within compounds.

Shilajit as a Vajikarana drug

Used for male reproductive vitality, one of the reasons for its modern popularity.

Shilajit for joint pain

Used in chronic Vata joint complaints, often alongside Guggulu.

Shilajit for anaemia

Its iron content and classical use in Pandu coincide, and it appears in some iron preparations.

Shilajit for kidney stones

A classical Ashmari drug used to help pass small stones.

Shilajit as a Yogavahi

Described as carrying and enhancing the action of drugs taken with it, which is why it appears alongside other Rasayanas.

Shilajit for cognitive function

A traditional use for memory and mental fatigue, with some preliminary modern interest.

Shilajit in classical formulations

Present in Chandraprabha Vati and most of the classical urinary and Rasayana compounds.

Frequently asked questions

What is Shilajit?

A mineral exudate that seeps from Himalayan rocks in summer heat — a blackish-brown resin formed over centuries from compressed plant material. It is not a plant, and Ayurveda classes it with the mineral drugs rather than the herbs.

What is the dose of Shilajit?

250–500 mg of purified resin per day, typically with warm milk. This is a small dose and reflects its potency — it is not measured in grams like a herb powder.

Is raw Shilajit safe?

No. Raw shilajit carries heavy metals, mycotoxins and free radicals, and must go through classical purification (Shodhana) before use. Buy only purified resin from a licensed manufacturer that publishes heavy-metal testing.

How do I know if Shilajit is genuine?

Genuine purified resin dissolves fully in warm water or milk leaving no grit, is sticky and softens with warmth, and has a distinctive tarry smell. Powders and capsules that will not dissolve, or material sold very cheaply, warrant scepticism.

Does Shilajit increase testosterone?

It is a classical Vajikarana drug and there is some preliminary modern work, but the evidence is limited. Its better-established classical uses are energy, urinary complaints and Prameha.

Who should avoid Shilajit?

Avoid in pregnancy and breastfeeding, in gout and high uric acid, in haemochromatosis or iron overload, and if you have active kidney stones. Take medical advice if you are on diabetes medication.

How long does Shilajit take to work?

It is a Rasayana, so eight to twelve weeks of consistent use. It is not a stimulant and will not produce an immediate effect — anything promising that is describing something else.
