The side effects and dangers of Dendrobium are unclear, but it should be taken as prescribed. Dendrobium is selected for clinical medicinal use as the fresh or dried stems of the cultivars of the orchid plants Dendrobium jinzhi, Dendrobium bulbosum and similar species of plants of the same genus. It has the effects of benefiting the stomach and generating fluids (nourishing the stomach by replenishing the fluids in the stomach), nourishing yin and clearing heat (nourishing the yin essence and clearing heat). It can be used clinically to treat symptoms such as dry mouth and tongue, thirst, poor appetite and dullness (lack of appetite and reduced food intake), and yellowing of urine caused by heat illness and insufficient fluid. In addition, the drug can also play a role in treating symptoms such as easy hunger, not wanting to eat, bone vapor and laborious heat, darkness of the eyes, impotence and weakness of the muscles and bones caused by a deficiency of yin in the stomach and kidneys. The side effects of Dendrobium are not clear. However, Dendrobium is strictly forbidden to be taken by those who have not yet injured their yin in the early stages of warm-heat disease, or those who have a deficiency of cold in the spleen and stomach (spleen and stomach are weak and cold). If you have symptoms, you must take the medicine under the guidance of a professional physician. Do not take the medicine blindly on your own to avoid delaying the condition or producing adverse reactions.
