Pharmacological action ① Central sedative effect

Glycerol rosin has similar sedative effect to Valeriana officinalis in frogs and rabbits, but its toxicity is stronger than that of Valeriana officinalis. The volatile substances of Gan Song broadleaf have similar sedative effect and have certain sedative effect. The organic solvent extract can induce sedation and pressor in mice, rats and cats by oral administration or intraperitoneal injection. The ethanol extract has the highest efficacy and is toxic in large dose, and1.5 ~ 3.75g/kg can cause death. Valerione is more effective in antagonizing the maximal electric shock than the volatile oil of Dalundine and Gan Song, but it has no protective effect on pentylenetetrazole-induced convulsion.

② Anti-arrhythmia

Valerione has antiarrhythmic effect and is a safe drug. The inhibition of ectopic ventricular rhythm (anesthetized dogs after secondary coronary artery ligation) is stronger than quinidine and Gan Song volatile oil; However, the inhibition of injured atrial flutter and aconite alkaline atrial fibrillation is the same as quinidine. The volatile oil extracted from the root of Gan Song broadleaf has a weaker effect on prolonging the anti-depression period and slowing down the conduction in various heart specimens than quinidine. It is also less toxic to mice by acute intravenous injection than quinidine. It has no protective effect on ventricular arrhythmia caused by digitalis.

③ Effect on smooth muscle.

Before and after injecting histamine into guinea pigs, Gan Song broadleaf can dilate bronchi. Alcohol extract has antagonistic effects on histamine, 5- hydroxytryptamine and acetylcholine in isolated smooth muscle organs (small intestine, large intestine, uterus and bronchus). It can also antagonize the spasm caused by barium chloride, so it has a direct effect on smooth muscle. Clinical treatment of asthma, cough, diarrhea and abdominal pain may be related to this.

④ Other functions

The volatile oil from Gan Song broadleaf has weak antibacterial, expelling wind and spasmolytic effects, and has no local * * * effect on skin and mucosa.
