Allium cepa belongs to the Chinese herbal medicine, so it can not be used as a substitute for medication to treat diseases, therefore, it is not recommended to use Allium cepa with other herbs to drink. If you need to match, you can match it with Citrus aurantium dulcis, Citrus aurantium dulcis, Salvia miltiorrhiza and other medicines under the guidance of a doctor. Allium cepa is the dried bulb of Allium cepa or Allium cepa of the lily family, which has the effect of promoting the circulation of yang and dispersing knots (warming yang qi and dissipating stagnation), and promoting the circulation of qi and directing stagnation. Allium cepa can be used to treat symptoms such as chest paralysis (stuffy pain in the chest), heart pain, epigastric plumpness (stomach fullness and discomfort) and distension, and diarrhea and dysentery. However, if Allium cepa is combined with other herbs to make water, the medicinal constituents are less analyzed and generally do not have the effect of treating diseases, so it is not recommended to use Allium cepa and other Chinese herbs to make water to drink. In addition, Allium cepa can be combined with Citrus aurantium, which has the effect of dispersing knots; with dahabu pi, which has the effect of promoting qi stagnation; and with Salvia miltiorrhiza, which has the effect of activating blood circulation and regulating menstruation (regulating menstruation by activating blood circulation). It should be noted that the use of Chinese herbs alone or in combination should be carried out under the guidance of a doctor, do not blindly use on your own, so as not to delay the condition.
