Pharmacological Action

1. Antitussive and expectorant effects

Quercetin 3-diglactoside and hyperoside contained in lacquer have antitussive effects. Hyperoside has a strong antitussive effect. The helium mist method on mice has shown that the antitussive effect of oral administration of 500 mg/kg hyperoside is no less than that of oral administration of 80 mg/kg codeine. However, the content of hyperoside in lacquer is very low. Wedgeroot 3-digalactoside has a similar structure and effect to hyperoside and is the main antitussive ingredient in lacquer. In addition, clinical laboratory tests found that the acidic mucopolysaccharide fibers in the sputum of patients taking Zeqi tablets were reduced. Therefore, it is speculated that Zeqi may inhibit the synthesis of acidic mucopolysaccharides and have an expectorant effect.

2. Anti-pain effect

Zeqi has inhibitory effects on mouse sarcoma S180, S37, mouse leukemia and other tumor strains. Two monomer substances, Zeqisi A and B, were isolated from Zeqi, and studies have shown that both have anti-cancer activity.

3. Other effects

In clinical practice, Ze La has a certain effect on tuberculosis, but its decoction, diluted fermentation extract and distillation liquid have no inhibitory effect on Mycobacterium tuberculosis in test tube.

4. toxicity

The emulsion of lacquer is highly irritating to the skin and mucous membranes. Contact with the skin can cause redness, or even inflammation and ulceration. However, when its decoction is taken orally in clinical practice, no obvious toxic reaction is observed even at a dose of up to 150g/kg, which may be because the toxic components are insoluble in water. If fresh grass or milky juice is accidentally ingested, the oral cavity, esophageal and gastric mucosa may become inflamed and eroded, with burning pain, nausea, vomiting, abdominal pain, and watery diarrhea. In severe cases, it may cause dehydration and even acidosis.
