Carl (or Karl) Heinrich Schultz (8 July 1798 in Altruppin – 22 March 1871), known as Carl Heinrich "Schultzenstein" Schultz, was a German physician and botanist.
The appellation "Schultzenstein" is a reference to his birthplace; this was necessary to distinguish him from his contemporary Carl Heinrich "Bipontinus" Schultz, also a German botanist.
From 1817 he studied medicine at Friedrich Wilhelms-Institut in Berlin, having designs on a career as a military physician.
He later traveled to Paris, where he advanced his theories involving the circulation of sap in plants.
[1] He was a proponent of Goethe's mystical "nature-philosophy" view of the natural world.
