On the History of Refining Mercury in Tibetan Medicine

Open access
Czaja, Olaf·2013·Asian Medicine

Abstract

<section class="abstract">In this brief study, the origin and spread of the alchemical process of refining mercury in Tibetan medicine will be explored. Beginning with early sources from the eighth to the twelfth centuries, it will be argued that Orgyenpa Rinchenpel (O rgyan pa Rin chen dpal) caused a turning-point in the processing of mercury in Tibet by introducing a complex alchemical process previously unknown. This knowledge, including the manufacturing of new pills containing mercury, soon spread through Tibet and was incorporated into the medical expertise of local schools such as the Drangti school (Brang ti). Later it was most prominently practised by Nyamnyi Dorjé (Mnyam nyid rdo rje) in southern Tibet. This particular tradition was upheld by Chökyi Drakpa (Chos kyi grags pa) of the Drigung school, who taught it to his gifted student Könchok Dropen Wangpo (Dkon mchog ’gro phan dbang po). During the seventeenth century, two main transmission lines for refining mercury emerged, one associated with the Gelukpa school (Dge lugs pa) in Central Tibet and one with the Kagyüpa school (Bka’ brgyud pa) and the Rimé movement (Ris med) in eastern Tibet. Both will be discussed in detail, highlighting important proponents and major events in their development. Finally, the situation in the twentieth century will be briefly explained. </section>

    The same Tibetan term, "Rin chen tsha sbyor," is identified elsewhere in the paper as the Precious Hot Compound, not the Precious Cold Compound.

    Minor

    The account dates the start of Orgyenpa's journey associated with acquiring the technique to about 1253. That does not support the conclusion's placement of his introduction of the technique in the early thirteenth century.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-05.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-05.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
