Sea hollyhock seeds are different from qian shi seeds, as they do not contain glycosides (including saponins), alkaloids, or the toxic proteins found in qian shi seeds. There have been reports of the presence of toxic compounds similar to abrin in sea hollyhock seeds, but they are used as a condiment by people in Africa. The roots have emetic and laxative effects, while the leaves have astringent properties and can be used to treat diarrhea. This is a brief overview of the related discussions.
