The element phosphorus in our homoeopathic laboratory.

The text and pictures below display how we manufactured the remedy Acidum phosphoricum for our pharmacy. The steps of production start with the preparation of the raw substance from cattle bones, later on followed by the trituration C 3 and succussion of the remedy.

S. Hahnemann, Chronic Diseases, Vol. V

Steps of manufacture:
1. Burning of raw bones and elimination of all organic parts.
2. Burned cattle bones - the starting material for the production of Acidum phosphoricum and phosphorus.
3. Dissolving of the burned bones in sulphuric acid (Ca₃(PO₄)₂ + 3 H₂SO₄ = CaSO₄ + 2  H₃PO₄)
4a. and 4b.: Pressing out the raw phosphoric acid (2 pictures).
5. A part of the phosphoric acid, which – for some reason – is wine red.
6. Concentration of a part of the phosphoric acid – the red colour vanishes quickly.
7. Final stage of the acid concentration at very high temperature; phosphorus pentoxide (P₂O₅) results, which reacts immediately with the humidity in the air to Acidum phosphoricum: P₂O₅ + 3 H₂0 ––> 2 H₃P0₄.
