For thousands of years, when a critically ill patient is in critical condition in the south, people will try their best to risk their lives to pluck "immortal grass" from the cliff and feed its juice into the patient's mouth to bring the patient back to life. Although this statement has its legendary color, it is reported that this medicinal material called "Life-saving Immortal Grass" does exist in the folk, and its scientific name is "Dendrobium candidum". Dendrobium officinale is one of the most precious Chinese herbal medicines, and is respected as the first of the "Nine Great Immortal Herbs", known as "Gold in Medicine".
 
 The application of Dendrobium candidum was recorded as early as the "Shen Nong's Materia Medica" in the late Eastern Han Dynasty. Many ancient medical works such as "Compendium of Materia Medica" and "The Great Dictionary of Traditional Chinese Medicine" have recorded the medicinal functions of Dendrobium candidum. The ten major effects are:
 
 1. Nourishes Yin and Jin: Dendrobium officinale "specially nourishes the qi and fluid of the lungs and stomach, and the qi and fluid are prosperous, and the kidney water is self-produced".
 
 2. Enhance physical fitness: Dendrobium candidum has the function of nourishing yin and nourishing blood. The Qing Dynasty "Medicinal Nature" said: Dendrobium candidum can invigorate the kidney and accumulate essence, nourish the yin of the stomach, and invigorate qi. It is rich in polysaccharides and has the effect of enhancing immune function.
 
 3. Tonic for the spleen and stomach: Dendrobium officinale is a medicine that nourishes the stomach and promotes body fluids. "Shen Nong's Materia Medica" and "Ben Cao Zaixin" have recorded that it is called "gastrointestinal medicine" and is a commonly used medicine for the treatment of epigastric pain and upper abdominal pain. Modern medical experiments have confirmed that Dendrobium officinale has a good inhibitory effect on Helicobacter pylori, a common pathogen in spleen and stomach diseases, and is helpful for the treatment of atrophic gastritis, superficial gastritis, duodenal ulcer and other Helicobacter pylori-positive diseases.
 
 4. Liver protection and gallbladder: Dendrobium candidum has a good gallbladder effect. Physicians of all dynasties believed that "Dendrobium candidum" has the effect of nourishing liver yin and is an essential medicine for the treatment of various hepatobiliary diseases.
 
 5. Strengthening tendons and lowering lipids: After a person enters middle age, Yin and Jin begin to weaken, and the function of muscles and bones gradually declines. Dendrobium officinale can nourish Yin fluid and lubricate joints, thereby achieving the effect of strengthening tendons and bones, fluent joints, and enhancing anti-rheumatism. Modern pharmacological research also shows that: Dendrobium officinale can improve stress ability, has good anti-fatigue, hypoxia resistance; can promote circulation, dilate blood vessels, reduce blood cholesterol and triglycerides.
 
 6. Lower blood sugar: Dendrobium officinale has the function of nourishing yin, clearing heat and moisturizing dryness, and has been a special medicine for the treatment of diabetes since ancient times. Clinical studies have shown that Dendrobium officinale can not only enhance insulin activity, but also significantly reduce blood sugar levels and restore blood sugar to normal.
 
 7. Inhibition of tumors: Dendrobium officinale has a killing effect on certain cells of malignant tumors such as lung cancer, ovarian cancer and promyelocytic leukemia, and has strong anti-tumor activity. Clinically used in adjuvant treatment of malignant tumors, it can improve the symptoms of tumor patients, reduce the side effects of radiotherapy and chemotherapy, enhance immunity, and improve the quality of life.
 
 8. Bright eyes: Dendrobium has the function of nourishing yin and nourishing eyes. Modern pharmacological studies have confirmed that Dendrobium has obvious effects on preventing and treating senile cataracts and protecting children's vision.
 
 9. Nourishes the skin: After the human body enters middle age, the yin fluid in the body decreases, which accelerates the aging of the skin, making it darken or wrinkled. The mucilage contained in Dendrobium officinale has moisturizing and nutritious effects on human skin.
 
 10. Longevity : "Shen Nong's Materia Medica" lists Dendrobium candidum as a holy medicine with the effect of "lightening the body and prolonging life". Modern pharmacological studies have confirmed that Dendrobium officinale contains a variety of trace elements, which are closely related to the health and longevity of the human body, and its anti-aging effects on the human body are more extensive and comprehensive than ordinary drugs.
 
 Our Dendrobium Officinale comes from the authentic five-year alpine (red pole) Dendrobium Officinale in the original deep forest of Xishuangbanna, Yunnan. It is grown organically in the wild environment of deep mountains above 1200 meters above sea level, with a humidity of 80% and an average temperature of 8.8°C. There is no industrial pollution, and the air quality is excellent. Of course, the dendrobium grown in this environment is better than that grown on the flat land. It has more glue and no slag! And our Dendrobium has been tested, and the polysaccharide content of Dendrobium is as high as 39.3, which is much higher than the standard! More completely free of pesticide residues (true, organically grown!)
 
 This Dendrobium officinale slices are dried at low temperature, which is convenient for daily tea brewing, and of course it can also be used in soup! Unlike in the past, it has to be soaked for a long time before it can be used.
