Ground Pine

Long before modern pharmacy existed, apothecaries prized the tiny golden spores of Lycopodium clavatum as vegetable sulfur, a powder so fine and water-repellent that it was dusted over pills and suppositories to keep them from sticking to the fingers or to one another. Wound dressers used that same silky powder on chafed skin and minor abrasions, valuing how readily it soaked up moisture without irritating tender skin. The trailing evergreen itself, gathered from shady woodland floors across Europe and North America, lent its name to one of homeopathy's most frequently prescribed remedies, prepared through extensive dilution rather than taken as a raw herbal dose. Stage magicians and early photographers also learned that a pinch of the spores, tossed near a flame, would ignite in a bright, quick flash, a trick still recalled in old accounts of traveling shows and early flash photography.
