Most pain oils tell you what they do. Very few tell you what they are.
Flip a typical balm and you get "herbal extracts" and a proprietary blend. Flip a classical Ayurvedic oil and you get a recipe that has been written down for centuries. Unsprain Oil is built from four of those recipes. Here is what each one is, what it was traditionally used for, and why they sit in the same bottle.
Quick answer
Unsprain Oil blends four classical medicated oils — Mahanarayan, Mahamasha, Prasarini and Mahavishgarbha Taila — all described in the Vatavyadhi (disorders of Vata) chapter of Bhaishajya Ratnavali. Together they are traditionally used for sprains, sore muscles and stiff joints. It is for external use only.
First: what is a "taila"?
A taila (तैल) is not an essential-oil blend. It is made by taila-paka: herbs are made into a paste (kalka) and a decoction (kwatha), then slowly cooked with a base oil — usually sesame (तिल) — sometimes with milk, until all the water has evaporated. The fat-soluble parts of the herbs stay in the oil. A single classical taila can carry thirty or more herbs.
Sesame is chosen deliberately: Ayurveda calls it the best oil for Vata — warm, heavy and penetrating. That is the base under all four oils below.
1. Mahanarayan Taila — the all-rounder
Mahanarayan Taila
महानारायण तैल · joints and musclesThe most widely used classical oil for Vata pain. Its long ingredient list includes Ashwagandha, Bala, Bilva, Shatavari and the ten Dashamula roots, cooked in sesame oil with milk. Traditionally massaged into joints and muscles for pain, stiffness and weakness. Also available on its own as Maha Narayan Tel.
2. Mahamasha Taila — nourishment for tired muscles
Mahamasha Taila
महामाष तैल · muscles and nervesBuilt on Masha (black gram, उड़द — Vigna mungo), a food Ayurveda considers deeply nourishing (Brimhana). The oil is traditionally used where muscles feel weak, wasted or numb, and in nerve-related stiffness. Available on its own as Mahamash Tel.
3. Prasarini Taila — for stiffness and movement
Prasarini Taila
प्रसारिणी तैल · stiffness and range of motionNamed after Prasarini (Paederia foetida, गंधप्रसारिणी) — "the one that spreads", a nod to its traditional use in restoring movement to stiff, contracted joints. Animal studies have reported anti-inflammatory and pain-reducing (antinociceptive) activity in Paederia foetida extracts (Chen et al., 2026; Arati et al., 2026) — early, pre-clinical evidence, but consistent with its traditional role.
4. Mahavishgarbha Taila — the potent one
Mahavishgarbha Taila
महाविषगर्भ तैल · pain and stiffness, external only"Vishgarbha" means "carrying poison in its womb" — an honest classical name. It includes potent herbs such as Dhattura and Vatsanabha that are used in tiny, processed amounts, and only on the skin. Traditionally for stubborn pain and stiffness. This is why Unsprain Oil must never be swallowed or used on broken skin.
Why blend four oils?
| Oil | Traditional emphasis | What it adds to the blend |
|---|---|---|
| Mahanarayan | Joints + muscles, general Vata pain | Broad foundation |
| Mahamasha | Weak, tired muscles and nerves | Nourishment after strain |
| Prasarini | Stiffness, restricted movement | Mobility |
| Mahavishgarbha | Stubborn pain and stiffness | Intensity |
A sprain is not one problem. It is pain, then stiffness, then weakness, then fear of moving. Each classical oil leans towards one of those. A blend covers the whole arc in one massage.
Unsprain Oil — a classical Vata-balancing blend for sprains, sore muscles and stiff joints.
Safety, plainly
- External use only — never swallow.
- Not on broken skin, open wounds, eyes or mouth.
- Patch-test first on the inner forearm.
- Ask a doctor before use in pregnancy or on children.
- Not on a fresh, swelling sprain — wait until the swelling settles (see Ice or heat?).
