Cistanche deserticola from Alxa is a geographical indication agricultural product.

　　Desert Cistanche is a unique and rare wild herbaceous plant that grows only in the Badain Jaran Desert of the Alxa region in Inner Mongolia, China.

　　And in the hinterland of the Tengger Desert. It is an extremely rare and unique wild herbaceous plant that survives for decades without emerging from the ground in the arid, rain-scarce desert hinterland known as the "Sea of Death," enduring temperatures as low as minus 20 degrees and as high as 50 degrees Celsius. Known as the "king of super xerophytes," desert Cistanche is rich in alkaloids, crystalline neutral substances, amino acids, trace elements, vitamins, and more. It contains a unique compound, Alxa Cistanche glycoside, not found in other plants, which is the most effective ingredient for delaying aging. Unlike other medicinal herbs, Cistanche does not grow in deep mountains or wild fields but thrives in the vast, arid, and rain-scarce deserts of western Inner Mongolia. It is primarily found in the depths of the Badain Jaran Desert, Tengger Desert, and Ulan Buh Desert. It is a purely natural, pollution-free wild green plant. Its appearance is peculiar, covered with scale-like "armor," with a cylindrical body that can grow up to 40–100 centimeters tall, and the heaviest single plant can weigh up to 10 kilograms. The decades-old "Cistanche kings" are very rare. Freshly sprouted young Cistanche, rich in moisture and nutrients, is the best time for harvesting. If left to grow, it consumes much of its internal moisture and nutrients, losing its economic value. The tender Cistanche, when its scale-like outer skin is peeled off, reveals white, sweet, and crispy flesh with abundant sap, making it a popular raw food among desert dwellers. Cistanche can also be a delicacy on the dining table—sliced thinly and stir-fried with potatoes, meats, or used in soups, it is delicious and flavorful.

　　Survival Environment

　　The extremely harsh survival environment has endowed Cistanche with remarkable and unique efficacy. It parasitizes the roots of the desert plant Haloxylon ammodendron. The tiny seeds of desert Cistanche, as small as dust, can survive in the desert for decades without dying, buried by shifting sand dunes. With slim chances of survival, they wait until encountering the roots of Haloxylon, where they parasitize and form spores, relying on the nutrients from Haloxylon to develop and grow. It takes at least 3 to 5 years to mature, with plants varying from 20 to 100 centimeters in height, and the heaviest single plant can reach ten kilograms (seven kilograms of fresh Cistanche can produce one kilogram of dried Cistanche). The best time for harvesting is between March and May each year.

　　Conservation Value

　　Cistanche is a valuable traditional Chinese medicine with economic worth. It is also a remnant plant of the ancient Mediterranean, holding certain scientific value for studying the central Asian desert flora. It is an endangered species. Due to excessive harvesting, its numbers have drastically declined. Surveys show that among every thousand host plants Haloxylon, only seven have Cistanche. Additionally, since Haloxylon serves as excellent fodder for camels and fuel for locals, overgrazing and extensive cutting of Haloxylon have also pushed Cistanche to the brink of extinction. Known as "earth spirit," Cistanche is currently one of the world's endangered species, with extremely high medicinal value, earning the reputation of "desert ginseng." Among the more than 60 kinds of tonic herbs discovered in China, it is considered the highest-grade, containing abundant amino acids, cysteine, vitamins, and rare mineral nutrients. It greatly benefits male reproductive organs such as the kidneys, corpus cavernosum, and has immediate and miraculous effects on erectile dysfunction and premature ejaculation. The "Supplement to Materia Medica" records: "Three qian of Cistanche, boiled three times and prepared, taken warm, ensures lifelong potency." However, Cistanche is extremely rare and endangered, with only small amounts found in China’s Xinjiang Tianchi Canyon, locally referred to as "living gold." A folk saying goes, "Better a basket of Cistanche than a bed of gold and jade." Along with ginseng and deer antler, it is ranked as one of China’s three great tonics.

　　Product Quality Characteristics

　　1. Botanical Features: Alxa Cistanche is a tall herbaceous plant, growing 40–160 centimeters high, mostly underground. The stem is unbranched or branches into 2–4 branches from the base, with the lower diameter reaching 5–15 centimeters and tapering upward to 2–5 centimeters. Leaves are broadly ovate or triangular-ovate, 0.5–1.5 centimeters long and 1–2 centimeters wide, denser at the lower stem and sparser and narrower upward, becoming lanceolate or narrowly lanceolate, 2–4 centimeters long and 0.5–1 centimeter wide, glabrous on both sides. The inflorescence is a spike, 15–50 centimeters long and 4–7 centimeters in diameter; the lower or entire bracts are longer, equal to or slightly longer than the corolla, lanceolate, lanceolate, or linear-lanceolate, along with the bracteoles and corolla lobes, sparsely pubescent or glabrous on the outside and edges; there are two bracteoles, ovate-lanceolate or lanceolate, equal to or slightly longer than the calyx. The calyx is campanulate, 1–1.5 centimeters long, with five shallow lobes at the apex, the lobes nearly round, 2.5–4 millimeters long and 3–5 millimeters wide. The corolla is tubular-campanulate, 3–4 centimeters long, with the apical lobe nearly semicircular, 4–6 millimeters long and 0.6–1 centimeter wide, often slightly revolute at the edge, with color variations of pale yellow-white or pale purple, often turning brownish after drying. There are four stamens, with filaments attached 5–6 millimeters from the base of the tube, 1.5–2.5 centimeters long, basally covered with curly long hairs, the anthers oblong, 3.5–4.5 millimeters long, densely covered with long hairs, with an abrupt apex at the base. The ovary is elliptical, about 1 centimeter long, with nectar glands at the base, the style slightly longer than the stamens, glabrous, the stigma nearly spherical. The capsule is ovoid, 1.5–2.7 centimeters long and 1.3–1.4 centimeters in diameter, often with a persistent style at the apex, splitting into two valves.
