1. antispasmodic effect The alcohol extract of dry lacquer has antagonistic effects on histamine, 5- hydroxytryptamine and acetylcholine in isolated smooth muscle organs (such as large intestine, small intestine, bronchus and uterus), which is similar to antihistamines, lysergic acid diethylamine (anti-5- hydroxytryptamine) and atropine, but its strength is weak.

2. Other dry lacquer water extraction preparations have no obvious effect on oxygen consumption of neonatal rat cardiomyocytes cultured in vitro.

The experimental observation of antithrombin effect showed that the coagulation time of dry lacquer extract (0.2g crude drug /ml) was not significantly prolonged compared with the control group. Different from Eupolyphaga Seu Steleophaga and Leech, it has strong anticoagulant effect.

The latest research found that

It was learned from Kunming Institute of Botany, Chinese Academy of Sciences that during the research on the drug prevention and treatment of chronic nephropathy, scientists of the institute found that some compounds contained in Chinese medicine dry paint had significant inhibitory effects on the over-secretion of extracellular matrix and proinflammatory factors in diabetic nephropathy, and dry paint may become a new drug for diabetic nephropathy.
