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, and only a small part is in sperm whales. At first, Long Xianxiang was excluded by sperm whales and floated in the sea. At first, its color was black. After a long period of seawater washing, 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 best quality. Long Xianxiang with good quality needs to be soaked in 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 Long Xianxiang directly taken from sperm whales is of little value, because it has not been soaked in seawater, so the value of this impurity-filled Long Xianxiang is relatively cheap.
The country first discovered by Long Xianxiang was ancient China. It first appeared in the Han Dynasty, when fishermen went out to sea to fish, and they would salvage some ash drift, which gave off a very fresh and strange smell after drying. After lighting, the aroma is very rich. At that time, local officials often bought these Long Xianxiang, gave them to the emperor, and used them as spices in the palace. The secret of Long Xianxiang's sperm whale was discovered by fishermen in Karath Island. On this island, fishermen kill sperm whales for a living. Some people discovered Long Xianxiang while dissecting the intestines of sperm whales. When the news was known by biologists at that time, they immediately conducted research and finally found that Long Xianxiang came from sperm whales. Long Xianxiang was formed because the sperm whale was stimulated to secrete a special kind of wax after swallowing mollusks, which wrapped the remaining things and gradually formed the Long Xianxiang.
Long Xianxiang can not only be used as a directional agent of perfume, but also be a precious Chinese medicine. It has the effects of promoting qi circulation, promoting blood circulation, resolving hard mass, relieving pain, regulating qi and resolving phlegm, and can be used for treating cough, asthma and chest pain.
