Extent: One unbound book consisting of 66 folios.
Size and dimensions of original material: Each folio is 55 cm x 9 cm.
Condition of original material: Several lines of text underlined in yellow pen. Woodblock illustration also filled in in yellow.
Custodial history: All the material was passed to the current owner by his father Labu Chherring, who inherited the bulk of the material from his father, Tsering Tashi Labu's grandfather. All three men trained to become amchi, doctors in the Tibetan tradition. Father and grandfather were, in addition, singers (nyahon) and speechmakers (molawa).
Arrangement: All the material was kept in the prayer room of Tsering Tashi Labu's house (unseen). The precise country of origin is unknown. However it is almost certain that the original text was created in Tibet, though the specific material in question may have been copied locally in Spiti (India) at a later date.
