Hi all,
The US and Australia have put forward a business case proposal (see attached) for creation of a new attribute for the Substance hierarchy which can be used to link a biological substance with the organism it is sourced from. E.g: Taipan venom (substance): IS A Venom (substance) , has originating organism = Oxyuranus scutellatus (organism). The topic was taken to the DEUSG in October and received support from the group. https://conf.spaces.snomed.org/wiki/spaces/USRG/pages/156598382/2025-10-20+DEUSG+Antwerp
Comments: This would help to clarify how organisms and their parts are used as ingredients in medications. The range of “Has active ingredient” remains unchanged to substances, and the organisms would be linked using the new relationship. The substance used as a medication ingredient can be the a protein, an extract, etc of the corresponding organism. The relationship between the two hierarchies would help to resolve any apparent duplication between these hierarchies.
