'What a wonderful creature': The rise, and fall, and rise again of leeches in medicine


First aid

Near the farming town of Echuca, on the border of Victoria and New South Wales, Brian breeds leeches for medical use.


These days, the parasites are used to help with things like reconstructive surgery and microsurgery, where they work to restore blood flow and prevent blood clots.
