There are more than 70 kinds of natural active substances in the body of giant salamander, which can promote human physiological activity, improve the cellular level of human physiological metabolism, promote protein synthesis, improve human immune function and enhance disease resistance. Giant salamander meat contains a lot of high-quality protein and trace elements, and is rich in 17 amino acids, among which 8 amino acids are essential for human body. The total amount of amino acids is as high as 9 1.92%, among which the content of essential amino acids is 39.69%.

Giant salamander is rich in metallothionein (MT), which can remove free radicals and excessive heavy metal ions in human body, thus regulating the circulation of micro-substances, preventing heavy metal poisoning and delaying aging, and can be used for the adjuvant treatment of cancer in the elderly. Giant salamander can promote DHA biosynthesis in cells, enhance immunity and improve disease resistance. Studies have shown that the super antigen PRCA can be extracted from the body of giant salamander, which is called "the response factor to induce cancer cell apoptosis" by the international health organization, and can kill cancer cells, inhibit the growth and metastasis of cancer cells, thus achieving the purpose of preventing cancer.

The skin of giant salamander contains 41%-61.3% of collagen, which can keep the skin elastic, smooth, healthy, white and tender, so it is called the holy product of beauty care and whitening, and has a strong beauty effect.

The skin, secreted glands, stomach and tail fat of giant salamander also have many functions. The liver of giant salamander has the effects of improving eyesight, clearing away heat and toxic materials, dissolving heavy metal toxins, enriching blood and benefiting qi, and the stomach of giant salamander can effectively enhance the function of human stomach, which has special effects on the treatment of gastric diseases. The cartilage of giant salamander is rich in selenium and the tail is rich in unsaturated fatty acids, which has a good effect on cardiovascular and cerebrovascular diseases. The skin powder of giant salamander mixed with tung oil can treat burns and scalds, especially the treatment of facial burns and scalds without leaving scars is even more magical, which can be described as a panacea for traumatology. The mucus secreted by its skin can prevent leprosy. At present, Chinese and Russian experts collect mucus from giant salamander in vitro by non-invasive mucus extraction technology, and use the world's most advanced enzyme membrane reaction technology to prepare giant salamander glinin II (giant salamander oligosaccharide peptide), which can scavenge "skin killer" oxygen free radicals in a short time, and has antioxidant, anti-aging, anti-ultraviolet and super immune activity.
