Shilajit, also known as silajit, salajeet or mumijo, momia and moomiyo,”shargai”, is a thick, sticky tar-like substance with a color ranging from white to dark brown (the latter is more common), sometimes found in Caucasus mountains, Altai Mountains, and Tibet mountains and mountains of Nepal.
Shilajit is a blackish-brown exudation, of variable consistency, obtained from steep rocks of different formations found primarily in the Himalayas of Nepal.
It is used in Ayurveda, the traditional system of medicine. Today, in the United States, supplement companies are selling Shilajit as an ingredient in testosterone boosting supplements. The composition of shilajit has been investigated numerous times in both Nepal, India and the former USSR, and depends on the location where it is found. It has been reported to contain at least 85 minerals in ionic form, as well as triterpenes, humic acid, and fulvic acid. A similar substance from the Caucasus Mountains and the Altai Mountains is called mumijo (Russian).
