WHAT IS IT? WHAT ARE THE BENEFITS? Bird's nest is made out of a solidified saliva produced by the males swifts/swallows. This saliva is very nutrient-rich so when consuming the nests, it provides lots of health benefits.Bird's nest is edible but is also used in skincare products. It's great for any age. Bird's nest is rich in protein, calcium, potassium, phosphorus, magnesium, iron and amino acid. It increases the body's resistance against disease, it reduces heat in the body, fortifies the spleen and digestive system and even promotes longevity (the process of ageing is retarded through the antioxidant content in the bird's nest). It also promotes the secretion of body fluids, stimulates cell regeneration and promotes blood circulation. These are well-known benefits of bird's nest that most Chinese people know. For women it results in young, radiant and fairer skin when consuming this often.
