Fossil record
2 fossil seeds of †Stemona germanica from the early Miocene, have been found in the Kristina Mine at Hrádek nad Nisou in North Bohemia, the Czech Republic. Fossil seeds of Stemona germanica have also been recorded from the nearby Hartau in Germany. Stemona fossil seeds are recorded from many European sites ranging in ages from the Maastrichtian to the Late Miocene.

Cultivation and uses
Stemona tuberosa (Chinese: 百部; pinyin: bǎi bù), is one of the 50 fundamental herbs used in traditional Chinese medicine.

Stemofoline alkaloids occur in the stems and leaves of Stemona species, particularly S. japonica and have been investigated for use as pharmacological and pesticidal compounds. The chemical structure of the insecticide flupyradifurone was inspired by stemofoline.
