saponins in panicoid grasses (Panicum, Brachiaria) Agave lecheguilla, Narthecium ossifragum, Tribulus terrestris are probably responsible for causing crystal-associated cholangiohepatopathy and subsequent secondary photosensitization; this is suspected as the cause of photosensitization associated with other plants. Called also steroidal saponin.
