Hyraceum names no single substance
A natural extractFossilised hyrax excreta IS collected and tinctured, so a material genuinely exists - we simply do not hold it. Recorded as a reconstruction here rather than left unclassified, but it is really an onboarding gap. The material that would realise this note is Hyraceum tincture; we do not hold it, so this edge names the gap rather than asserting a reconstruction.
