The lower part of the stem rises obliquely to lie flat, the upper part is upright, with a few dichotomous branches, and the branch ends often have spores. Born under the shade of trees, wetlands, shrubs, roadsides or valley stones at an altitude of 300-2700m. It is distributed all over the world. When the whole herb is used as medicine, Huperzia Serrata Powder has the effects of clearing heat and detoxification, generating muscle and hemostasis, dispersing blood stasis and detumescence, treating traumatic injury, blood stasis, swelling and pain, internal injury and bleeding, external use, carbuncle, poisonous snake bite, scald, etc. However, the product is toxic, and symptoms such as dizziness, nausea and vomiting can occur when poisoned.
The hemlock is a shade fern. The suitable ecological environment is the middle subtropical evergreen broad-leaved forest, the subtropical monsoon evergreen broad-leaved forest and their degraded secondary ecosystem. The artificial Cryptomeria fortunei forest or the Artificial Cunninghamia lanceolata Forest and moso bamboo forest on the shady slope are also conducive to its growth. Under wild conditions, Huperzia serrata propagates mainly through spores and reproductive buds, but the spore germination cycle is long. After germination, gametophyte is formed underground, which takes 6-15 years to mature. It is also reported that it takes 15-20 years from spore germination to plant maturity. In fact, Huperzia serrata propagates rarely through reproductive buds, which greatly limits the regeneration of wild resources.
Huperzia Serrata Powder is mild in nature, bitter, pungent and slightly sweet in taste. It has the effects of hemostasis and blood stasis, detumescence and pain relief, heat clearing and dehumidification, detoxification and so on. It is mainly used to treat traumatic injury, internal injury, hematemesis, blood in urine, hemorrhoids, leucorrhea, swelling poison, oral ulcer, scald and other diseases.
