⑴ Cross section of the stem of this product: nearly square or rectangular, with four edges and corners, three of which are obvious. The epidermis consists of 1 row of rectangular cells, and sometimes multicellular or unicellular non-glandular hairs can be seen outside. The cortex is narrow, and some parenchyma cells contain yellowish brown pigment. The fiber bundles of stele sheath are mostly arc-shaped and arranged intermittently in a ring shape. The vascular bundle is infinitely tough and the pith is hollow. Cross section of main vein of leaf: the upper and lower epidermal cells are rectangular or square, and there are many cells without glandular hairs, especially in the upper epidermis. Fences are organized in a row. The main vein obviously protrudes from the lower surface, and the vascular bundle of the main vein is tough outside, with 2~3 parallel or connected in a half-moon shape. Surface view of leaves: the upper epidermis is conical without glandular hairs, consisting of 3-5 cells or more, with a length of 170-450μ m, a base diameter of about 70μm and a sharp tip. A long or oval reddish-brown pigment block can be seen along one side of the vein. The vertical wall of the lower epidermal cells is curved, the stomata are uncertain, and there are 3~4 accessory cells.

1.* * * Similarity: Both drugs grow on roadsides, wasteland, ditches and other places, and fruits will stick to people's clothes. Because of their special smell, pigs, cattle, sheep and other animals do not eat these two herbs raw. But after cooking, you can still feed the pigs and make pig feed. These flowers are yellow. Harvest the whole grass from June to165438+1October. They all have the effects of clearing away heat and toxic materials, resisting bacteria and diminishing inflammation, and can be taken in a thermos cup instead of tea. Can be used for treating common cold, sore throat, dysentery and other diseases.
Second, the difference:
In fact, as long as the two drugs are carefully observed and compared, they can still be accurately distinguished.
(1) stems are different: the stems of Leymus chinensis are generally nearly round; The stems of Bidens bipinnata are usually quadrangular.
⑵ The leaves are different: the big wolf has 3 ~ ~ 5 leaflets opposite the pinnately compound leaves, which are lanceolate; Bidens bipinnata bipinnata leaves opposite or alternate, trifoliate or indehiscent;
⑶ Different flowers: The wolf has no tongue-shaped flowers, but there are well-developed leaflike bracts under the inflorescence; Bidens bipinnata has white or yellow tongue-shaped flowers.
⑷ Different fruits: The big wolf flattened achenes with two short spines at the top; Bidens bipinnata achene is rod-shaped with 3~4 short spines at the top;
5] Different functions and indications:
Stellera chamaejasme has the effect of strengthening yin and nourishing yin, so folk Chinese medicine is often used alone or in combination to treat diseases such as physical weakness, indigestion, tuberculosis, night sweats, urinary tract infection and hepatitis.
Bidens bipinnata has the effect of promoting blood circulation and removing blood stasis, so folk Chinese medicine often treats snake bite, traumatic injury, appendicitis, hemorrhoids, chronic ulcer, chilblain, hypertension, hyperlipidemia and other diseases alone or in combination.
Through the above analysis, we can understand why some people's physical strength and energy will be greatly increased after drinking Bidens bipinnata tea, but the main reason why hypertension and hyperlipidemia have not come down is that some people mistake "wolf treating grass" for "Bidens bipinnata".
Practice has proved that Bidens bipinnata can lower blood pressure without side effects.
Identification of dried products:
We can start with their own fruit characteristics. Achene is flat and has two thorns at the top, which is the grass pulled by the wolf. Achene is slender, rod-shaped, with 3 ~ 4 spines at the top, which is Bidens bipinnata or has the same effect as Bidens bipinnata. Of course, there are also a few Bidens bipinnata with only two thorns at the top. Chinese name: Bidens bipinnata (Compendium of Materia Medica, Textual Research)
