Is Long Xianxiang the vomit of whales?

Hello, Long Xianxiang is whale vomit. This statement is not rigorous. Long Xianxiang is the dried product of intestinal secretion of sperm whale in physeteridae. Some sperm whales will spit out clots, others will be excreted from the intestines, and only a few sperm whales will leave Long Xianxiang in their bodies. Long Xianxiang's character is opaque waxy rubber, black and brown like amber, sometimes with colored stripes. Crisp and light, chewy and sticky like wax. The smell is slightly fishy and sweet. The specific gravity is about 0.7 ~ 0.9, the melting point is 60℃, and it can be dissolved in pure acid. When it burns, it gives off a blue flame and the fragrance is overflowing. It looks like musk, very elegant. Smoked things can keep a lasting fragrance. It is best to be dark brown, loose and tough, and it has a fragrance when burned. This sperm whale mainly lives in tropical and warmer waters; One male and many females live in groups. Distributed all over the ocean. China has the East China Sea and the South China Sea. So it is not entirely correct to say that Long Xianxiang is the vomit of whales. Dragon fragrance is an animal fragrance. With musk, civet cat and seafood, it is called the four major animal fragrances. It has been paid attention to by people since ancient times because of its complex but balanced fragrance and lasting fragrance fixing ability, as well as its medicinal effects of nourishing and strengthening yang, diminishing inflammation and relieving pain. In ancient China, Long Xianxiang was regarded as a precious aphrodisiac. /kloc-in the 7th century, the western pharmacopoeia recorded that Long Xianxiang had therapeutic effect on heart and brain diseases and could prevent plague. Long Xianxiang, as a medical treatment, can mainly promote qi and blood circulation, dissipate stagnation and relieve pain, and induce diuresis to relieve stranguria. Used for cough, asthma, qi stagnation, chest pain and gonorrhea. Long Xianxiang alcohol itself has no fragrance, but it changes in the air to produce fragrance. So it can also be used as a high-grade perfume. After Long Xianxiang purchased by perfume company is graded, Long Xianxiang perfume is ground into very fine powder, dissolved in alcohol, and then mixed with 5% Long Xianxiang solution, which is used to prepare perfume or as a fixative. Therefore, Long Xianxiang is very expensive, almost equivalent to gold. Besides, the scientific research on Long Xianxiang has never stopped. Longshengxiang is mainly composed of triterpene alcohol Long Xianxiang and a series of cholesterol, in addition to a small amount of p-cresol and diethyl phthalate. At the same time, the pure product of Dalong Salicyl Ether was separated from ambergris tincture. These chemicals give off different smells. Chemical platform 2 emits decaying animal excrement, 3 shows faint tobacco smell, 4 shows typical seawater smell, 5 shows unpleasant seawater smell, 6 shows harmonious, delicate and lasting musk animal smell, and its levorotatory body has obvious woody smell. It has been proved that ambergris alcohol can produce the above five substances with Long Xianxiang aroma through oxidation or photodegradation. However, due to the low output of natural Long Xianxiang, ambergris alcohol is mostly synthesized by chemical methods. At present, Su Xiang alcohol is usually synthesized by a series of chemical transformations and then reacting with (+)-γ-dihydroionone. Because Long Xianxiang is a kind of stone formed after intestinal pathological changes of sperm whales. As the sperm whale is on the verge of extinction, 1970, the US Congress passed a ban on the production, sale and use of any goods made from sperm whales in the United States. Since then, the International Whale Commission has signed a memorandum banning commercial whaling in 1985 to protect this species. thank you
