Club moss

background

Club moss grows along the ground and reproduces by producing spores, rather than seeds. Lycopodium clavatum has been used in folk medicine to treat bladder and kidney disorders and to increase urine flow. There is insufficient available evidence in humans to support the use of Lycopodium clavatum for any condition.
According to the U.S. Department of Agriculture (USDA) PLANTS database, numerous species of club moss belong to two separate genera in the Lycopodiaceae family: Lycopodium and Huperzia. There is some overlap between the scientific names for species in both genera. The information in this monograph refers to the species Lycopodium clavatum.
Club moss species that contain huperzine, a cholinesterase inhibitor (e.g., Huperzia serrata, Lycopodium serrata) have been mistaken for Lycopodium clavatum and ingested, resulting in cholinergic poisoning.
