Anti-inflammatory effect: It can inhibit capillary hyperpermeability, resist histamine or reduce the responsiveness of cells to stimulation; it has inhibitory effects on carrageenan-induced plantar edema of rats, cotton ball granuloma of rats, formaldehyde edema, and subcutaneous granulomatous inflammation.

Expectorant effect: The platycodon saponins contained in it can increase the secretion of mucus in the respiratory tract and promote the discharge of bronchial mucosal fluid; at the same time, it reflexively causes an increase in the secretion of bronchial mucous glands, diluting the sputum and making it easier to cough up.

1. Expectorant effect: The platycodon saponins contained in this product can increase the secretion of respiratory mucus and promote the discharge of bronchial mucosal fluid. At the same time, this product can stimulate the nerve endings of the gastric mucosa, reflexively causing an increase in the secretion of bronchial mucous glands, making the sputum dilute and easier to cough up. 2. Antitussive effect: After oral administration, this product can cover the inflamed pharyngeal mucosa, reduce its stimulation, and relax the bronchial smooth muscle, playing an antitussive effect. 3. Anti-inflammatory effect: This product contains glycyrrhizin and glycyrrhetinic acid, which can inhibit capillary hyperpermeability, resist histamine or reduce the responsiveness of cells to stimulation. This product has an inhibitory effect on carrageenan-induced plantar edema in rats, cotton ball granuloma in rats, formaldehyde edema, and subcutaneous granuloma inflammation.

It has atropine-like parasympathetic inhibitory effect, and can cause mydriasis and accommodation paralysis after drug absorption

It has a sympathetic nerve excitatory effect, and after absorption, it manifests as mydriasis and local vasoconstriction

Antiviral drug. It has the effect of inhibiting the growth of many viruses such as respiratory syncytial virus, influenza virus, hepatitis A virus, adenovirus, etc. in vitro, and its mechanism is not fully understood. This product does not change the adsorption, invasion and uncoating of viruses, nor does it induce the production of interferon. After entering the virus-infected cells, the drug is rapidly phosphorylated, and its product acts as a competitive inhibitor of viral synthase, inhibiting inosine monophosphate dehydrogenase, influenza virus RNA polymerase and mRNA guanosine transferase, thereby causing a decrease in intracellular guanosine triphosphate, impairing viral RNA and protein synthesis, and inhibiting viral replication and transmission. It may also have an immune effect and neutralizing antibody effect on respiratory syncytial virus.

Not yet clear

This product can inhibit viral DNA and RNA polymerase, thereby inhibiting viral reproduction. On human embryonic kidney cells, 1% concentration has a significant inhibitory effect on DNA viruses (adenovirus, herpes virus) and RNA viruses (echovirus), and has an inhibitory effect on all stages of the viral proliferation cycle. It has no direct effect on free viral particles.
