As far as the shape of the stem is concerned, the thicker the stem of Dendrobium candidum, the better. The quality fresh strips of Dendrobium candidum are generally shorter than longer. In addition, the transverse section of Dendrobium candidum is bright green, with obvious colloid and crystal clear appearance.
