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. Eu Yan Sang Imperial Golden Bird’s Nest with Rock Sugar is specially prepared from wholesome, premium grade bird’s nest, which has been carefully selected and meticulously hand cleaned to best preserve its natural golden colour. It is ready-to-drink and suitable for consumption by all ages and can be taken chilled or warmed.
