Effects of the second (ethanol) extract of ginseng on the cardiovascular dynamics of dogs during halothane anesthesia.

An electromagnetic flowmeter probe was chronically implanted around the ascending aorta in a group of dogs. Subsequently, ten dogs were lightly anesthetized with halothane (0.75%), and a second (ethanol) extract of ginseng (40 mg/kg) was administered intravenously. Five dogs were anesthetized without the administration of ginseng. Eleven cardiovascular variables including cardiac output, stroke volume, heart rate, mean arterial pressure, pulse pressure, central venous pressure, total peripheral resistance, pH, PaCO2, PaO2, and base deficit were compared for two hours. The heart rate and mean arterial pressure were significantly decreased following ginseng. There were no other meaningful changes in either group.

Effects of the third (aqueous) extract of ginseng on the cardiovascular dynamics of dogs during halothane anesthesia.

An electromagnetic flowmeter probe was chronically implanted around the ascending aorta in a group of dogs. Subsequently, ten dogs were lightly anesthetized with halothane (0.75%) and the third (aqueous) extract of ginseng (40 mg/kg) was administered intravenously. Five dogs were anesthetized without the administration of ginseng. Eleven cardiovascular variables including cardiac output, stroke volume, heart rate, mean arterial pressure, pulse pressure, central venous pressure, total peripheral resistance, pH, PaCO2, PaO2, and base deficit were compared. The cardiac output, stroke volume, and central venous pressure were decreased significantly, while total peripheral resistance was increased significantly following ginseng.

Ginseng: its history, dispersion, and folk tradition.

This article presents a historical comparison of the traditions surrounding and uses of ginseng in Asia and in North America, with a focus on the triangle formed by the Chinese, the North American Indians, and the white American residents. The medicinal and folkloric applications of ginseng by the Chinese were remarkably similar to those independently developed by various North American Indian tribes. White Americans, however, largely disregarded the herbal root medicinal qualities in favor of the lucrative economic gains available from the export of ginseng to supply the Chinese market. Information was gathered primarily from Western sources and whenever possible was either drawn from or corroborated by original eighteenth and nineteenth century publications.

Influence of ginseng on mating behavior of male rats.

Experiment on the mating behavior of male albino rats paired with receptive females established that in comparison with control animals, males under the influence of ginseng (a) began ejaculation earlier and repeated the action more often in a 45-minute observation period and (b) deposited more copulation plugs in 10 days. The data suggest that ginseng facilitates the mating behavior of male rats.

The effect of ginseng on lifespan and stress responses in mice.

It has been suggested that ginseng can increase long-term resistance to stress and disease and therefore affect the lifespan. We set out to investigate this idea by testing whether the continuous administration of ginseng could affect the lifespan of mice and/or their behavioural responses to stress. 270 mice of strain LACa were divided into three groups: one group which was given ginseng from 8 weeks of age, a second group which was given ginseng from 52 weeks of age and an untreated control group. The mice were generally healthy. Their weights remained stable throughout their lifespan and were not altered by ginseng. Ginseng administration did not significantly alter the lifespan. However, ginseng did cause an exaggeration of the behavioural responses to mild stress. This effect was noticeable soon after ginseng administration and subsequently was maintained.
