Gelsemiol is primarily used in scientific research due to its neuroactive properties. It interacts with the central nervous system and has been studied for its potential in understanding neurological pathways, particularly those related to anxiety and sedation. Researchers use gelsemiol as a tool compound to investigate the function of specific ion channels and neurotransmitter receptors. Its structural features also make it a subject of interest in the development of novel bioactive molecules. However, due to its toxicity, it is not used in clinical or therapeutic applications and is strictly limited to laboratory studies under controlled conditions.
