Notes
1. Nests built by other species in the same genus—such as the short-billed swiftlet and the brown-backed swiftlet—are also used medicinally. 2. Commercially available bird’s nests are classified as white nests, hairy nests, and blood nests. White nests (official nests) are pure white, occasionally containing a few feathers; hairy nests are gray in color and contain a relatively large number of grayish-black feathers; blood nests contain reddish-brown blood streaks. White nests are considered the highest quality. 3. Patients requiring treatment with traditional Chinese medicine should first consult a licensed TCM hospital, where a TCM practitioner will conduct a professional pattern differentiation and issue a prescription.
Processing & Preparation

Processing Methods

Crude Drug Identification
Properties of Crude Drugs
Intact specimens are irregularly crescent- or boat-shaped, often concave into a pouch-like form, 6–10 cm long and 3–5 cm wide; the surface is yellowish-white or grayish-white, with the side attached to the rock relatively flat and the other side slightly convex; the interior of the pouch is rough, resembling a loofah, and fine feathers are visible under a magnifying glass.The texture is hard and brittle; the cross-section is fine-grained with a horn-like luster. When soaked in water, it softens and swells, becoming crystal-clear and translucent; it feels elastic when lightly pressed. It has a faint fishy odor and a slightly salty taste; chewing it produces a sticky, slippery sensation.
