Pharmacological effects of Chuanxiong

1. Effects on the central nervous system

Chuanxiong has a significant sedative effect. A small amount of Chuanxiong volatile oil has an inhibitory effect on the activity of the animal brain, but has an excitatory effect on the medulla oblongata respiratory center, vasomotor center and spinal reflex center. The ig administration of Chuanxiong decoction to mice and rats could inhibit their spontaneous activities, prolong the sleep time of mice induced by sodium pentobarbital, and counteract the excitatory effect of caffeine (20 mg/kg). However, it cannot counteract the convulsions induced by pentylenetetrazol in rats. Oral administration of 25-50g/kg of Chuanxiong decoction can inhibit the spontaneous activity of rats, and the sedation effect on mice is more obvious than that on rats; it can also prolong the sleeping time of pentobarbital, but cannot antagonize the excitement of caffeine, nor prevent the convulsion or lethal effects of pentamethyltetrazolium and cocaine. The volatile oil of Japanese Chuanxiong has an inhibitory effect on the activity of the animal brain, and an excitatory effect on the vasomotor center, respiratory center and spinal reflex of the medulla oblongata. When the dosage is increased, all of them turn into inhibition.
