Long Xianxiang is actually the secretion of sperm whales. This secretion may sometimes be spit out by sperm whales, or it may be discharged from the intestines of sperm whales, with only a small part in sperm whales. At first, Long Xianxiang was excluded from the sperm whale and floated in the seawater. At first, its color was black. After a long period of washing in the seawater, its color gradually faded, from the initial light black to gray, light gray and white. Under the action of seawater scouring and soaking, the initial impurities in Long Xianxiang are slowly floated out, so relatively speaking, white Long Xianxiang is the most expensive and the quality is the best. Long Xianxiang with good quality needs to be soaked in recycled seawater for at least several decades, and even some Long Xianxiang needs to be soaked for more than a hundred years to reach white. This also shows that the Long Xianxiang directly taken from the sperm whale is of little value, because it has not been soaked in seawater, so the value of this Long Xianxiang full of impurities is relatively cheap.
The country that Long Xianxiang first discovered was ancient China. It first appeared in the Han Dynasty, when fishermen fished in the sea, they would salvage some gray drifts, and after drying them, they smelled very fresh and strange. After lighting it, the aroma is very strong. At that time, local officials often bought these Long Xianxiang and gave them to the emperor to be used as spices in the palace. The secret that Long Xianxiang came from sperm whales was discovered by fishermen from Saudi Arabia's Cautrat Island. On this island, fishermen make a living by killing sperm whales. Some people discovered Long Xianxiang while dissecting the intestines of sperm whales. After the news was known by biologists at that time, they immediately studied and finally found that Long Xianxiang came from the sperm whale. Long Xianxiang was formed because the sperm whale, after swallowing the mollusk, was stimulated to secrete a special wax, which wrapped up the remnants of things and gradually formed the Long Xianxiang.
Long Xianxiang can be used not only as a directional agent for perfume, but also as a valuable Chinese medicine. It can promote qi circulation and blood circulation, dissipate stagnation and relieve pain, regulate qi and eliminate phlegm, and can be used to treat cough, asthma, and chest pain.
