A Behavioral Assay to Examine the Effects of Kavalactones on Caenorhabditis elegans Neuromuscular Excitability.

Kavalactones are a class of lactone compounds found in Kava, a traditional beverage from the South Pacific Islands that is derived from the root of Piper methysticum. When consumed, these compounds produce sedative and anxiolytic effects, suggesting their potent actions on the nervous system. Here, we provide a protocol to examine the effects of kavalactones on C. elegans neuromuscular excitability. Our methodology could provide insight into the neurophysiological actions of kavalactones.
