Considering its unique composition as a phytocomplex, very rich in fulvic acid, researchers hypothesize that Shilajit is produced by the decomposition of plant material from species such as Euphorbia royleana and Trifolium repens. This decomposition seems to occur through centuries, and on this basis, shilajit is considered a millenary product of nature. However, further studies have identified that several other plant organisms may generate shilajit, such as molds as Barbula, Fissidens, Minium, and Thuidium and other species like Asterella, Dumortiera, Marchantia, Pellia, Plagiochasma, and Stephenrencella-Anthoceros.
