1. The appearance of Dendrobium: When we identify the authenticity of Tiepi Fengdou, we can first look at it. For processed dendrobium, there will be a layer of fine hair, which is formed after the stem skin fibers are dried. If there is a layer of fine hair on the surface, it means it is real Dendrobium officinale.

2. The size of Dendrobium: Secondly, its shape and workmanship should be fine, the size should be uniform, and the particles should be relatively full, then it is a real Dendrobium officinale. Its segments are distinct, short, numerous, and thick, thin at both ends and thick in the middle. In terms of stem shape, the thicker the stems of Dendrobium officinale, the better. At the same time, high-quality fresh Dendrobium officinale stems are generally shorter rather than longer.

3. Color of dendrobium: Because of its high sugar content, the genuine dendrobium will be darker and appear yellow-green. If it is waxed, it will be reflective. Dendrobium rubbed with newspaper dust can be touched out with your hands, leaving dust marks on your fingers. In addition, the cross-section of Dendrobium officinale is fresh and tender green, and obvious gum can be seen, with a crystal clear appearance. High-quality fresh strips of Dendrobium officinale have very little or even no fiber, so if the fiber can be easily seen from the cross section, the Dendrobium officinale is usually fake

4. The smell of Dendrobium: put one around your nose and smell it When you smell it, genuine Fengdou will emit a faint grassy aroma instead of other peculiar smells. Taste and texture Traditional Chinese medicine classics record that Dendrobium officinale has a slightly sweet or bland taste, with a fresh grassy aroma. When you actually taste Dendrobium officinale, you can still feel the obvious sticky feeling of gum, and even if you chew it for a long time, there is very little residue of Dendrobium officinale. If the Dendrobium officinale purchased by consumers tastes bitter or sour when chewed, or has too little juice and too much residue, it can be concluded that its quality must be poor.

5. The surface of dendrobium is stretched: that is, pulled by hand. Pull the maple bucket from the middle to both sides. Generally, if the sugar content is relatively high, it will break in the middle with just a slight pull. If it can be stretched very long and there is no sign of breakage, it can be judged as fake Dendrobium officinale. This is an important method to identify its authenticity.

6. Market price of dendrobium: Another point is the price of dendrobium, which can also determine its authenticity. Many maple trees that appear on the market are called Dendrobium officinale, but in reality most of them are sold with purple bark or Dendrobium aquatica as the iron sheet. As everyone knows, the real Dendrobium officinale is a medicinal material that you get what you pay for, and its price is also directly proportional to the market conditions at that time. If it is low, it is definitely not Dendrobium officinale.
