American ginseng has certain auxiliary effects in treating insomnia. American ginseng contains a variety of ginsenosides, which have a wide range of effects, mainly in tonifying the qi, benefiting the yin and generating fluid, and can be used to sedate and help sleep, anticonvulsant, antiarrhythmic, anti-hypoxia, anti-fatigue and anti-stress conditions, but the application of American ginseng alone generally has limited effects. It is necessary to determine specifically whether American ginseng can help patients with insomnia according to the cause and type of insomnia. Patients with insomnia caused by Qi deficiency, Yin deficiency, or Qi-Yin deficiency often show lazy speech, fatigue, night sweating, dry mouth and tongue, and severe tooth marks on the tongue, etc. This type of patients can be relieved to a certain extent by using American ginseng, but it is not recommended to use American ginseng alone. American ginseng can be brewed with boiling water and used as a tea. For insomnia caused by certain organic lesions and mental diseases, such as pain caused by inflammation and swelling, as well as insomnia caused by severe depression and mania, such patients usually also have symptoms such as fever, severe local pain, depression and irritability, etc. Relying on American ginseng usually cannot achieve the effect of treating insomnia. The cause of insomnia should be clarified in time, and appropriate treatment should be actively applied to help patients alleviate their condition and thus improve their insomnia symptoms. In addition, when applying American ginseng, it should be noted that because American ginseng can replenish qi but does not produce heat, it may aggravate discomfort after consumption, and not everyone is suitable for applying American ginseng, such as cold, wind-cold and women during menstruation should not be applied, and the use of drugs should be adjusted under the guidance of doctors.
