Shilajeet (Sanskrit: शिलाजतु, śilājatu,Salajit in urdu)[1] or mumijo is a thick, sticky tar-like substance with a colour ranging from white to dark brown (the latter is more common), found predominantly in Himalaya, Karakuram, Tibet mountains, Caucasus mountains, Altai Mountains, and mountains of Gilgit Baltistan .[2][3]

Shilajeet is a blackish-brown exudation, of variable consistency, obtained from steep rocks of different formations found in the Altai Mountains.

It is used in Ayurveda and Unani, the traditional Indian system of medicine. It has been reported to contain at least 85 minerals in ionic form, as well as triterpenes, humic acids[4][5] and fulvic acid.


The English word shilajeet is a phonetic adaptation of "śilājīt" (Hindi: शिलाजीत), which in turn goes back to Sanskrit (Sanskrit: शिलाजतु, śilājatu)[1]. The literal meaning of the Sanskrit compound is "mountain tar", the first element शिला (śilā) meaning "pertaining to, or having the properties of a rock, mountain", the second - जातु (jatu) denoting "gum, lac; any tarry substance"[6]

Shilajeet comes from the Sanskrit compound word shilajatu meaning "rock-tar", which is the regular Ayurveda term. It is also spelled shilajeet (Hindi: शिलाजीत) and salajeet (Urdu: سلاجیت‎).

Shilajeet is known universally by various other names,[7] such as mineral pitch or mineral wax in English, black asphaltum, Asphaltum punjabianum in Latin, also locally as shargai, dorobi, barahshin, baragshun (Mongolian: Барагшун), mummenayyee (Farsi مومنایی), tasmayi (Kazakh: тасмайы, lit. rock oil), [8] brag zhun (Tibetan: བྲག་ཞུན་), chao-tong, wu ling zhi (Chinese: 五灵脂, which generally refers to the excrement of flying squirrels), badha-naghay (Burushaski for "feces of a featherless flying squirrel), baad-a-ghee (Wakhi for "devil's feces"), and arkhar-tash (Kyrgyz: архар-таш).[7] The most widely used name in the former Soviet Union is mumiyo (Russian: мумиё, variably transliterated as mumijo, mumio, momia, and moomiyo), which is ultimately from Latin (mumia) body-preserving, a borrowing of the medieval Arabic mūmiya (مومياء) and from a Persian mūm (موم) or mūmiya (مومیا).


Euphorbia royleana, a possible botanical source of the shilajit gum

Several researchers have noted that Shilajeet is unlike mineral tar seeps and is most likely of vegetable origin. The cactus like plant Euphorbia royleana has been observed growing near collection sites and is suggested as a likely origin as its gum has a similar composition.[9]

One more recent hypothesis states that the species of Asterella, Dumortiera, Marchantia, Pellia, Plagiochasma and Stephenrencella-Anthoceros have been growing in shilajeet neighborhood and it is these plants, mosses and liverworts that during centuries have been fueling the Shilajeet deposits generation[10]

Thallose liverwort, a potential "mother" for shilajeet


According to ancient Indian sources Shilajatu was born from a friction of the celestial spheres during Samudra Manthana episode. The Devas and the Asuras agreed to churn the primal Ocean in order to obtain the beneficial Amrita substance.

"Divine Sweating" during Samudra Manthana process which is said to beget Shilajeet

They wrapped the king snake Vasuki Naga around Mount Mandara, which was used as a churning rod, and mixed the primordial Milk Ocean The Gods and Demons had been sweating hugely during the elaborous churning process. And their sweat interacted with the divine nectar. So originated Shilajeet deposits were distributed about the mountains of the world[11]


The first documented reference to Shilajeet in the form of "Shilajatu" dates back to the sixth century BCE. Sushruta Samhita, a third century CE Sanskrit medical treatise states: "A gelatinous substance that is secreted from the [12]side of the mountains when they have become heated by the rays of the sun in the months of Jyaishta and Ashadha. This substance is what is known as Šilájatu and it cures all distempers of the body.[13] During medieval era, Shilajeet had been considered one of the rasa (nutritive fluid) to endow a person with magical power when taken with particular metals, bhasmas, herbs, ghee or honey. A famous alchemical Siddhanjana also known as the "ointment of Mags" included camphor, shilajatu, some psychoactive herbs, as well as metal oxides and minerals. It allegedly enabled the practitioner to see "all the seven worlds of Hell (Patala)". [14] Shilajeet is found predominantly in Himalaya, Tibet mountains, Altai and Caucasus mountains. The color range varies from a yellowish brown to pitch-black, depending on composition. For use in Ayurvedic medicine the black variant is considered the most potent. Shilajeet has been described as 'mineral oil', 'stone oil', 'Mountain Blood' or 'rock sweat', as it seeps from cracks in mountains due mostly to the warmth of the sun. There are many local legends and stories about its origin, use and properties, often wildly exaggerated. It should not be confused with ozokerite, also a humic substance, similar in appearance, but apparently without medicinal qualities.

Once cleaned of impurities and extracted, shilajeet is a homogeneous brown-black paste-like substance, with a glossy surface, a peculiar smell and bitter taste. Dry shilajeet density ranges from 1.1 to 1.8 g/cm3. It has a plastic-like behavior, at a temperature lower than 20°C (68°F) it will solidify and will soften when warmed. It easily dissolves in water without leaving any residue, and it will soften when worked between the fingers.

It is still unclear whether shilajeet has a geological or biological origin as it has numerous traces of vitamins and amino acids. A shilajeet-like substance from Antarctica was found to contain glycerol derivatives and was also believed to have medicinal properties.[15]

Health benefits[edit]

The proposed immuno-modulatory activity does not stand the test of critical assessment and is considered as unproven.[16]

Shilajeet has been the subject of scientific research in Russia and India since the early 1950s. In the former USSR, medical preparations based on mumiyo/shilajeet are currently sold in Russia as a daily recuperative health tonic.[17]
