The nests are considered to have a high nutritional and medicinal value, believed to retain everything from anti-aging and anti-cancer properties, to the ability to improve concentration and raise libido. Protein is the most abundant constituent of the nests, containing all of the essential amino acids.
The nest also contain six hormones (including testosterone and estradiol), carbohydrates, ash, and a small quantity of lipids (naturally occurring molecules that include fats). Previous research has indicated that the nests have substances that can stimulate cell division and growth, enhance tissue growth and regeneration, and inhibit influenza infections. But the most special ingredient of all in bird’s nest soup is "nutri-collagen," which helps in collagen formation.
