The Lycopodium spore method in pharmacognosy is a technique used to identify and quantify plant materials based on the unique morphology of Lycopodium spores. This method involves mixing the plant sample with Lycopodium spores, which serve as a reference for counting and analyzing the particulate matter in the sample. By assessing the ratio of spores to the plant material under a microscope, researchers can determine the purity and authenticity of herbal products. It is particularly useful for quality control in herbal medicine and ensuring compliance with pharmacopoeial standards.
It is an important technique for powdered drug ,especially when chemical & other method fail as accurate measure of quality. Lycopodium is composed of spores of lycopodium elavatum.I. Each spore is tetrahedral in shape, The base is rounded and the threeside wallmakes the three well marked covering ridge, which join one other at filled with fixed oil. The spore are exceptionally uniform in size(25µm) and the shape tetrahedral so that one can always know that a definite no. of spore present in particular weight of lycopodium. On an average 94000 spores per mg of powdered lycopodium are present. Using this figure one can calculate the weight of any number of spores under any condition underthe microscope.
Lycopodium produces spores known as homosporous spores, which are all of the same size and shape, allowing for a uniform dispersal method.
Pharmacognosy Reviews was created in 2007.
Pharmacognosy Communications was created in 2010.

Lycopodium Clavatum also called Wolfsfoot
lycopodium is mainly used for lower parts
Lycopodium is a clubmoss which is homosporous
An abstriction is a method of spore formation in fungi in which successive portions of the spore are cut off through the growth of septa.
at is the difference between natural products and pharmacognosy
