2025-06-10
I.Plant Traceability: Yam Extract
Yam is mainly produced in Henan, Hebei, Shandong and other regions of China, especially famous for authentic varieties such as "Iron Stick Yam" in Wen County, Henan. As a "top-grade" medicinal herb recorded in the "Shennong Bencao Jing", it has a sweet and flat nature, and is used to nourish the spleen, lungs, and kidneys. It is traditionally used to invigorate the spleen and stomach, nourish yin and moisten dryness. Modern research has found that the health benefits of yam are closely related to its growth environment: sandy soil in temperate monsoon climate endows its roots and stems with natural advantages in enriching active ingredients such as polysaccharides, saponins, and mucin.
II. Ingredient Decoding: Synergistic Health Benefits of Multiple Active Substances
The core efficacy of Yam Extract comes from the "golden combination" of four major categories of ingredients:
1. Polysaccharide complexes - dual regulators of immunity and metabolism
Rich in components such as mannan and glucose. By regulating the AMPK signaling pathway, it can promote hepatic fatty acid oxidation and assist in weight management.
2. Steroid saponins - guardians of anti-inflammatory and glucose and lipid metabolism
Represented by dioscin, it has significant anti-inflammatory activity and can inhibit the expression of inflammatory factors TNF - α and IL-6.
3. Mucin - the natural barrier between the intestine and mucous membranes
The unique glycoprotein structure of Yam Extract contains a large number of hydroxyl groups, which can form a protective film on the surface of the gastric mucosa, reducing the stimulation of alcohol and drugs on the gastric wall. Animal experiments have confirmed that as water-soluble dietary fiber, it can promote the proliferation of probiotics and improve constipation.
4. Synergistic network of trace elements and polyphenols antioxidants
Rich in trace elements such as zinc, selenium, and manganese, as well as flavonoids, phenolic acids, and other components, it has an antioxidant capacity equivalent to three times that of blueberries, can clear free radicals, and delay cell aging.
