Materials and methods
Male Sprague-Dawley rats were given methamphetamine (1 mg/kg) intraperitoneally and the locomotor activity and ultrasound vocalization (USV) expression were measured. Electrophysiological methods were used to investigate a possible neuronal mechanism in the brain.
Ja-Geum-Jung attenuated METH induced increases in the locomotor activity and USV. Acupuncture enhanced these effects showing a synergistic effect in the combination with Ja-Geum-Jung. Also, amygdala was shown to be involved in these effects.
Combination of acupuncture and herbal formula has been demonstrated to make better effects than alone treatment on the METH, in parallel with the experience of thousands of years in the Eastern Asia.
