Drynaria is a unique genus of epiphytic ferns known for their distinctive shield-like sterile fronds. These specialized leaves play a crucial role in the plant's survival by collecting organic debris and moisture from the forest canopy. In various traditional medicinal practices, different species within this genus are highly valued for their therapeutic properties. To harness these benefits, the plant is commonly processed through the preparation of a decoction. This method involves boiling the plant material in water to extract its active medicinal compounds.

Preparations
Drynaria is prepared as a decoction to be used as a key component in traditional Chinese medicine formulations. In the studied research, this decoction was administered to Wistar rats via intragastric administration at a dosage of 6 g/kg/day. This specific method of preparation allows the plant to be tested for its effects on bone remodeling during orthodontic tooth movement. The study utilized this decoction to observe how it influences neovascularization and new bone formation in periodontal tissue. Ultimately, the application of the Drynaria decoction was shown to be beneficial to alveolar bone remodeling by promoting osteoclast differentiation.
