Ascaridole as a pharmacologically active principle of "Paico," a medicinal Peruvian plant

"Paico," Chenopodium ambrosioides L., is a traditional Peruvian medicine which is considered to be nervine, antirheumatic, anthelmintic, etc. An attempt was made to isolate the component having sedative and/or analgesic properties from "Paico" and "Aritasou" (the Japanese name for C. ambrosioides). Ascaridole was identified as the active principle in both materials.
