Drug identification [Character identification]: The whole grass grows 15-30cm. Slim. Stems are four prisms, 2-5mm in diameter, yellow-green to dark purple on the surface. The leaves are opposite, crumpled or coiled. After flattening, they are ovate and lanceolate. They are 1.5-3cm long and 0.5-1cm wide. They are softly pilose, with dark green above and grayish green below; petiole is short or nearly inorganic. The tops of the branches have racemes on one side of the twigs, with remnants of pods and sometimes four small nuts. The stems are soft and easy to break. Gas slightly, taste bitter. It is better to use green and sweet. [Microscopic identification]: leaf surface view: epidermal cells long-angled, vertical wavy curved wall, the upper epidermal cells are larger, and some cells with orange peel crystal, more common around the stomata; stomatal straight axis type. Non-glandular hairs 1-4 cells, walled with verrucose projections, base cells with incident-like texture. There are many glandular scales, round heads, more than 4-10 cells, diameter of 25-47μm, shape of large round or oval, and some edge irregularities, composed of dozens of cells, diameter 140-266μ. Another small glandular hair, round head type, 1-2 cells, a diameter of about 28μm, short stems, single cells. With low-power, miniature size, the serial communication department range sensor with mm accuracy can measure up to 20m, 40m, 60m, 100m, 150m, 200m.
