3cm wide, with a slightly pointed apex, a broad wedge-shaped base, and edges. Blunt teeth, brown-green surface, slightly rough on both sides, and white fine hairs on both sides. The inflorescence is drawn out from the leaf axils, unisexual, without petals; the bracts are triangular and kidney-shaped. The capsule is small, triangular and semicircular, 3-4cm in diameter, with a light brown surface and coarse hairs. The smell is slight, the taste is bitter and astringent.

Identification of drug applications

Amaranthus amaranth and gardenia are both important drugs for clearing away heat and promoting diuresis, and are both important drugs for cooling blood and detoxifying. The amaranth plant is light on the surface and clears away the dampness and heat on the surface of the muscles; the gardenia fruit is heavy on the inside and clears away the dampness and heat on the internal organs. The former goes outside, the latter goes inside. The effects are roughly the same, but the indications are different.

Pharmacological effects

Amaranth amaranth decoction has antibacterial effect on several common Shigella dysenteriae in vitro, especially effective against Shigella dysentery (2-fold dilution in test tube method), when the dilution is 1:256, it not only has antibacterial effect, but also has bactericidal effect. It is less effective against Shigella schuginii and Shigella freundii, and has the worst effect against Shigella sonnei. Tablets made from amaranth also have the same effect against Shigella dysenteriae in vitro. 50% iron amaranth decoction has varying degrees of antibacterial effects on Staphylococcus aureus, Vibrio cholerae, Bacillus anthracis, and Shigella shigei in vitro (agar plate method); its roots, stems, and leaves all contain antibacterial ingredients, but they are Different bacteria and different parts of the plant seem to have different antibacterial effects; the alcohol extract of amaranth also has the same antibacterial effect. The active antibacterial and antiasthmatic ingredient isolated from amaranth is gallic acid, which has inhibitory effects on Staphylococcus aureus, Diplococcus pneumoniae, and Group A Streptococcus, and has a dilating effect on the bronchi of guinea pigs and cats.
