Club mosses are primitive, spore-producing plants in the family Lycopodiaceae, with creeping or upright stems covered in tiny, scale-like leaves that give them a mossy appearance.
Despite their name, they are not true mosses but are more closely related to ferns and were among the earliest vascular plants on Earth.
These plants are found across temperate and tropical regions worldwide, particularly in forest understories, bogs, and mountainous areas of North America, Europe, Asia, and South America.
In traditional medicine, club mosses have held various uses depending on species. Lycopodium clavatum has been widely used in European and Native American herbal traditions as a diuretic, wound powder, and remedy for digestive and urinary tract issues, while the spores were used externally for skin protection and as a drying agent. In Chinese medicine, Huperzia serrata is used to support memory, reduce inflammation, and calm the nerves, often as a treatment for age-related cognitive decline.
Through scientific investigation, Club Mosses have been found to have antioxidant, anti-inflammatory, antimicrobial, neuroprotective, hepatoprotective, analgesic, and anticancer activities.
The spores of certain species, especially Lycopodium clavatum, have long been used in pyrotechnics, flash photography, and theatrical effects due to their extreme flammability.
They have also been used as pill-coating powders in pharmacy for their hydrophobic and non-reactive properties.
Though not commonly used in textiles or as food, club mosses have been part of ritual and symbolic practices in some Indigenous traditions.
Huperzine A, a compound isolated from Huperzia serrata, and other Lycopodium alkaloids, have gained significant scientific and medicinal interest for their neuroprotective properties, particularly in relation to Alzheimer’s disease and age-related cognitive decline.
Huperzine A’s primary mechanism is as a potent, reversible acetylcholinesterase inhibitor, meaning it helps increase levels of acetylcholine in the brain (a neurotransmitter crucial for memory and learning). Studies have also shown that Huperzine A exhibits antioxidant, anti-inflammatory, anti-excitotoxic, and mitochondrial-protective effects, making it a multifaceted agent in neurodegenerative research. It is currently being studied as a nootropic supplement and investigated in clinical trials for dementia and other cognitive disorders.
