The high quality edible bird's nests were introduced into China only 450 years ago in the Ming Dynasty. Historical evidence indicated that it was Admiral Cheng-Ho that brought the precious nests from Southeast Asia to the Chinese emperor. These precious clumps of dried saliva were barter traded with the Tang ceramics. Bird's nest has been recognized as a royal food with the ability to nourish the yin, and moisten lungs.
The most precious nutrients of the bird's nest are the varieties of glycol-proteins available within. They constitute about 80% of the edible portion. It is interesting to note that the modern research are verifying the TCM traditional claims. For example, it has always been said that bird's nest is good for the skin. In the 1990's, researchers successfully isolated a unique substance in bird's nest named the epidermal growth factor (EGF). EGF is responsible for skin and tissue repair and full potential of this substance is still being investigated.

Bird's Nest is the nutrient-rich salivary secretion of swiftlets. This gel secretion is an integral component to building the swiftlet nests, which are found in dangerous and highly inaccessible locations like steep cliffs, overhanging crags and deep caves.
Out of more than 30 species of swiflets, only 2 species of the genus Aerodramus and 1 of the genus Collocalia make edible saliva nest. Aerodramus fuciphaga is the swiftlet that produces the highest quality of edible Bird’s Nest, because its nests are white and clean with minimum feathers. It is found only in Southeast Asia. Tedious process of cleaning approximately 10 nests takes approximately 8h by a person1.
The major components of EBN are its glycoproteins, carbohydrates and trace elements. Scientific findings by the researchers in Chinese University of Hong Kong discovered that epidermal growth factor (EGF) is present in EBN. They demonstrated an epidermal growth factor (EGF)-like activity in aqueous extract of edible bird’s nest that stimulated the DNA synthesis in 3T3 fibroblast in a dose dependent manner in vitro2. EGF is a low-MW polypeptide, which stimulates cell growth and proliferation, demonstrating properties of skin and tissue repair.
Major carbohydrates consist of sialic acid (9%), N-acetylgalactosamine (galNAc) (7.2%), N-acetylglucosamine (glcNAc) (5.3%), galactose (16.9%) and fucose (0.7%). There had been studies showing that sialic acid aids in moderating the immune system receptors, preventing entry of bacteria and viruses. The carbohydrate also benefits the brain development of infants3. The other carbohydrate components present demonstrate important roles in signal transduction in cellular communication.
The most abundant amino acids are serine, threonine, aspartic acid, glutamic acid, proline, and valine1, 4.
