　　Huaxian Huazhou Yam is a specialty agricultural product of Huaxian, Shaanxi. In September 2006, it was certified as a pollution-free agricultural product after review by the Agricultural Product Quality and Safety Center of the Ministry of Agriculture. It features a thick stem, long shape, thin skin, fine texture, and rich flavor. Rich in sugar and protein, it is a highly nutritious and popular vegetable. Additionally, it contains saponin mucilage, allantoin, choline, amylase, and other substances, giving it high medicinal value.

　　Huazhou Yam is a tuberous root plant that grows underground. Huazhou is located in the lower reaches of the Wei River, where the sandy riverbank soil is loose and fine—providing ideal growing conditions. In early spring, farmers in areas such as Huazhou, Liuzhi, Xiamiao, and Chishui dig trenches about three feet deep in their vegetable fields, spread farmyard manure or oil residue and soybean cake, place yam seedlings with sprouts, cover with soil and tamp it down, then flood irrigate and wait for sprouting and vine growth. In summer, they set up supports, water, and weed. Harvest takes place in autumn. Today, Huaxian farmers use advanced modern trenching machines to dig trenches, implement pollution-free cultivation, apply scientific fertilization, and manage meticulously, continuously improving yield and quality. To date, high-quality yam cultivation in Huaxian has expanded to 5,000 acres.

　　Huazhou Yam has sturdy stems and straight vines, typically with a stem diameter of about 5 cm and a length of 70–80 cm. Its color is brown on the outside with white flesh inside, and it tastes sweet. It contains various vitamins, amino acids, and essential trace elements such as iodine, phosphorus, calcium, and iron, making it an excellent tonic. According to ancient records in the Huazhou Annals: “Scholars and officials often gave it as a gift,” and it has been widely loved through the ages. The yam is fine-textured and sticky, and scientific tests show it is extremely rich in protein, amylase, choline, and polysaccharides, capable of treating a variety of illnesses. The Compendium of Materia Medica states: Huazhou Yam, together with Huai Yam, is used in traditional Chinese medicine to “alleviate lower back pain and treat deficiency fatigue”; “nourish kidney qi, strengthen the spleen and stomach, stop diarrhea, dissolve phlegm, and moisturize the skin.” It dispels cold, removes heat, generates vitality, and fortifies the foundation. The mucoprotein polysaccharides it contains have special therapeutic effects in preventing arteriosclerosis. Long-term consumption of yam improves hearing and vision, refines skin texture, and prolongs life.

　　Huazhou Yam, with its sparse fuzz and thin skin, is easy to clean and cook, beloved by all and renowned as a premium tonic. Common home-style dish sweet-and-sour yam slices are crisp and delicious. Even better is sautéed yam seeds sliced from the yam vines. As a sweet dish, yam can be prepared as honey-glazed yam, candied yam, or fried sesame yam chips, which nourish qi, calm the spirit, moisten the lungs, and nourish kidneys. As a savory dish, such as braised yam, trotter yam, or yam with beef, it nourishes yin, expels pathogens, strengthens bones, and builds sinews. When cooked into yam porridge or soup, it regulates qi, harmonizes the middle, beautifies the complexion, combats aging, and is smooth and tender—suitable for all ages.
