Clubmoss Overview
Clubmoss, also known as lycopodium, is a plant that belongs to the Lycopodiaceae family. Clubmosses are native to many parts of the world, including North America, Europe, and Asia, and are known for their small, fern-like leaves and spore-producing structures.
Clubmoss, both the plant and spores, has a long history of use in traditional medicine and herbal remedies. The plant is believed to have a number of medicinal properties and is used to treat a variety of conditions, including bladder and kidney disorders, respiratory problems, digestive issues, and skin irritation. Some studies suggest it may also have anti-inflammatory and antioxidant effects. Clubmoss needs to be used cautiously as it contains potentially toxic alkaloids, including lycopodine, dihydrolycopodine, and traces of nicotine.
