The most valuable substance in sea urchin is the mixture of salivary glycolipid in gonad, including alcohol acyl ceramide, glucose and ceramide. These substances can directly supplement and repair the nerves, and these nutrients are almost absent in other foods. Sea urchins contain a lot of amino acids, meat contains dehydrogenase, and more importantly, sea urchins contain anti-tumor cancer glycoprotein. It can not only repair nerves, but also resist cancer, and it has been confirmed by medicine. This is incomparable to other foods. It is also the value of sea urchins.

However, sea urchins contain water-soluble fats such as protein, and the nutritional components of sea urchins are slightly different. This is a beautiful masterpiece, unparalleled. Sea urchin mainly contains phospholipids and polyhydroxynaphthoquinone. The unfertilized eggs of the carved sea urchin contain catalase, and the gonad contains squalane, which has both nutritional and health care values. "Primitive Materia Medica" records that sea urchins have the effect of "treating pain", and Chinese medicine believes that "sea urchins are salty, soft and hard, and have the effect of eliminating phlegm and reducing swelling". Sea urchin shell, sea urchin thorn and sea urchin yolk can treat gastric and duodenal ulcer and otitis media. Modern medicine believes that sea urchin can promote human microcirculation. Therefore, people with qi deficiency and stagnation are suitable to eat more sea urchins. Of course, in contrast, people with yang deficiency, yin deficiency and blood stasis can't eat sea urchins.

Not all sea urchins are edible, and there are many poisonous species. These sea urchins look much more beautiful than nontoxic sea urchins. For example, lizards that grow between coral reefs in the South China Sea have black and white stripes on their thick spines and yellow stripes on their thin spines. The young ring stings the sea urchin with white and green ribbons, shining, and the top of the thin thorn has barbs. Once it penetrates the skin, the venom will be injected into the human body, and the fine thorn will break in the skin, causing local redness and pain, and sometimes there will be poisoning symptoms such as heartbeat and general spasm.
