Shilajit (, مامي in Farsi or Dari, śilājatu, سلاجیت in Urdu) or Mumijo is a blackish-brown powder or an exudate from high mountain rocks, often found in the Himalayas, Karakoram, Nepal, Girda (Buldhana, MH, India), Russia, Mongolia and in the north of Chile, where it is called Andean Shilajit. While Shilajit has been used in traditional Indian medicine, there is no reliable evidence for its efficacy.
