Recipes for elixirs are concentrated in the fourth Chapter of Baopu-Tzu. In the 11-th set out the pharmacology of the compositions, and in the 16-th-recommendations for the production of gold.
The author of the treatise explains why plant and organic components are not suitable for making the elixir of immortality: they are subject to rot, and therefore short-lived. Only minerals are ideal. The "Golden elixir" is nothing more than a combination of gold and cinnabar. It is the guarantee of achieving results. Cinnabar as a result of chemical transformations synthesizes mercury (called liquid silver) and, in reverse order, returns the mineral back.
These recipes include various minerals, so the onset of immortality occurs in different time intervals (from a few days to several months). Attention is also paid to the interaction of the body with poisons, which are converted into compounds with arsenic, mercury, sulfur, and lead included in them. According to the author, often such chemical poisons have a beneficial effect on a person, for example, they clear the mind, give a feeling of lightness, and counteract diseases.
Mandatory condition: substances must necessarily be purified, processed by fire, which for a certain time is maintained in one state.
GE Hong in his recipes does not exclude the use of a wide range of additional components, such as realgar, mica, silver, natural jade. Various fossils, stalactites, and resins can be useful. A certain criterion for the possibility of using such additives is their ability to not decompose for a long time (for thousands of years). Only then can such a component be recommended for inclusion in the recipe of the elixir of immortality.
Anyone who takes up the study of recipes for longevity from the treatise "Baopu-Tzu", there is a risk of encountering an inaccurate translation. However, if there is a link to Hot transmutation somewhere, then this is an error. In the Tao, we are only talking about Cold transmutation of chemical elements.
Another important point that draws the attention of readers of "Baopu-Tzu" is that, in addition to chemical elements, the properties of the "Golden solution" are affected by the Great Primordial " (tai Yi). Literally, it is one of the stars in the constellation Sivaoan. The metaphorical translation means the same immortal germ maturing in the body.
