Śāla is the sal tree, Shorea robusta. Sarjarasa is the sticky resin that oozes from cuts in its bark, dried into brittle yellow-to-amber lumps. In Ayurveda it is used mainly on the skin — in wound dressings, ointments and medicated oils — and it is burned as a cleansing incense.
This is a single drug, not a formula. You may also see it sold as sal resin, sal dammar, ral or Indian dammar. The wood, bark and seeds of the same tree are used separately, so check which part you are buying.
Honest evidence verdict: sarjarasa has deep classical standing in Ayurveda, but we could not find published human trials testing it for any condition. Long traditional use is not the same as proof that something works, and that distinction applies to everything below.
The short answer: nobody has shown how it works in people, and the explanations below are ideas, not proven facts.
Ayurvedic texts describe sarjarasa as drying, astringent (tightening) and healing for wounds. That fits what a plant resin does physically — it forms a sticky film over a sore, which may shield it and reduce weeping.
Laboratory work on sal resin and its triterpene compounds reports antibacterial and anti-inflammatory activity in dishes and in animals. Results in a dish do not tell you what happens on a person's skin or in a person's gut.
Raw resin lumps, sold for burning as incense or for melting into preparations.
Coarse powder (churna) of the dried resin.
Medicated oils and ghee, where the resin is cooked into a fat base for use on the skin.
Ointments, plasters and wound pastes (lepa) combined with other herbs.
Dhūpana — the resin burned on charcoal so the smoke fills a room, traditionally for purifying air and fumigating sickrooms.
Sal is one of the great timber trees of northern and central India and has religious as well as medical standing.
Sarjarasa appears in classical Ayurvedic surgical and pharmacological literature, including wound-care and fumigation contexts, and stays in use in Indian folk practice today for skin complaints, ulcers and diarrhoea. It is a long-standing staple of a single tradition rather than a drug shared across many.
See a doctor if a wound gets more red, hot, swollen or smelly, or if red streaks spread from it, or if you get a fever — these are signs of infection.
See a doctor if diarrhoea lasts more than two days, contains blood, or comes with a high fever or signs of dehydration such as very dark urine or dizziness on standing.
See a doctor if a rash spreads, blisters or does not settle within a few days of stopping.
Get emergency help straight away for swelling of the face, lips or tongue, a tight throat, or sudden difficulty breathing.
