Herbal identification Morphological identification The whole grass is wrinkled into a group and there are sometimes fine filaments on the lower stem section. Stems twisted, about 1mm in diameter; surface red-brown, with vertical and straight texture; solid cross-section, gray. Leaves opposite, mostly shrinking and shattering, full leaves broadly ovate or heart-shaped, entire, dark green to brownish green above, lighter underneath, water immersed, light visible black short streaks; petiole slender, leaf axils sometimes Visible flowers or fruits. Gas slightly, tasteless. It is better to use large and green leaves. Microscopic identification Stem cross-section, epidermis outside the stratum corneum, sometimes visible glandular hairs. The cortex is broad, and the thin-walled cells contain red-brown secretions; there are 5-10 secretory cells scattered around, with red-brown secretions; the endothelial layer is obvious. The pleated fibers are micro-wooden and discontinuously looped. The phloem is narrow and there are occasional fibers in the xylem of the old stem. The marrow often becomes a cavity. This product is a parenchyma cell containing starch grains. Leaf cross section: The upper epidermis is a column of tangentially elongated parenchyma cells, oblong, stratum corneum, and no stomata. The lower epidermal cells resemble the upper epidermis and have stomata. Palisade organization often 1, sparse 2 columns. Sponge cells 4-6 columns, occasionally containing red-brown pigment blocks, secretory road hash, diameter 45μm. The main vein is 1 and it protrudes significantly below. Near the epidermal cells and phloem outside the thick angle tissue, vascular bundle surrounded by vascular bundle sheath. Lateral veins are small and underdeveloped. Leaf surface view: Peripheral wall of epidermis cells is slightly wavy, with a stratum corneum, glandular hair reddish-brown, head single cells, round in shape, stalk is multicellular, leaving a circular base after detachment, surrounded by a radial cuticle texture; Underlying epidermal cell stomatal inequality or infinitive; mesophyll tissue secretory tract scattered, containing red and brown secretions. Non-glandular hairs can be seen on the stems and leaves of coarsely pilose hair. There are 1-17 cells in nonglandular glands, 60-1070 μm in length, 15-53 μm in diameter at the base, straight or curved, with fine streak on the surface, and a yellow brown cell surface. Material, some cells contract. Hifentâ„¢ high flow heated respiratory humidifiers for homecare, a new type of oxygen therapy device.The device can provide stable fraction of inspired oxygen in a certain range,give mixture gas of warmed and humidified air and oxygen to the needy, so as to achieve better airway management and improve oxygenation level.
