Dendrobium Nobile, also known as the Noble Dendrobium or Shi Hu in Pinyin, has been used for the medicinal purpose for at least 2,000 years. The evidence is the related record in “Shen Nong’s Herbal Classic”, which was written 2300 to 2780 years ago (the Warring States Period). This is a rare and precious Chinese herb and the main medicinal part is the stem. It usually grows atop the perpendicular cliff walls and is exposed to the moisture of dew and rain as well as to the essence of the sun and moon throughout the year. Thanks for that, TCM believes that it owns such rich and balanced pharmaceutical ingredients that it can be used clinically in the treatment of a variety of disorders, such as chronic pharyngitis, gastrointestinal disease, eye disease, thrombotic occlusive disease, diabetes, arthritis, cancer, and so on.
