About Blood Nest

Blood Nest is one of the four major traditional food supplements in China and has been regarded as the top precious product among delicacies. The four major traditional food supplements include Blood Nest, ginseng, shark’s fins and abalone while the eight precious products include Blood Nest, fox lip, camel hump, monkey head, bear palm, deer tendons, dried meat & ect. The practice of Blood Nest consumption by the Chinese can be traced to the Tang Dynasty where it was already one of the “royal tributes”. It was said that Queen Wu Ze Tian was one of the emperors in those days who loved Blood Nests. In the later part of the 17 th century, large quantities of Blood Nest were imported into China from Jakarta in Jawa each year. Blood Nests is a structure made from the saliva of swallows combined with other substances and what Westerners consider called “EDIBLE BLOOD NEST” is actually Blood Nests which can be eaten. The golden swallows which build such edible Blood Nests are different from the ordinary swallows we see. They are smaller in size with longer and sharper wings, shorter tails, thinner legs, strong flying capabilities and seldom walk or stand. They sleep or rest just like bats, by anchoring themselves onto structures. They utilize well-developed salivary glands to secrete saliva which solidifies when exposed to the air. Golden swallows build their nests three times a year and when they are about to lay eggs, their bodies grow fat and their saliva production increases, resulting in their ability to build larger nests. In times of urgency, they would use other building materials such as their own feathers, grass and roots and mix them with their saliva to build their nests. In fact, the reason swallows build their nests three times a year solely for the purpose of laying eggs for propagation purposes. They stay in each nest only once, waiting for their nestlings to grow up and leave the nest. Swallows take about forty five days to build their nests, seven to ten days to lay eggs and about fifteen days to hatch them. Swallow nestlings would be able to fly after forty five to fifty days. This process takes about one hundred and ten to one hundred and twenty days and harvesting of Blood Nest is done after the young swallows have flown away. The lifespan of golden swallows is about fifteen to twenty years. The Blood Nest production in South East Asia is mainly concentrated in Indonesia, Malaysia, Thailand, Burma and Vietnam. Among these nations, Malaysia produces the best quality Blood Nest .Quality is one of the important factors considered by those who love Blood Nest.
