The efficacy and effect of Plantain with Chen Pi is to dissolve phlegm, relieve cough and diuretic. Psyllium has the functions of clearing heat, diuretic, clearing lymph, expectorating phlegm, cooling the blood and detoxifying the toxin (referring to the treatment of blood-heat and toxin-containing). In clinical practice, it can be used for symptoms such as heat drenching (burning and stinging pain is obvious when urinating, accompanied by frequent urination and urgency, and discomfort of traction in the abdomen) and astringent pain, edema, dysuria, summer-dampness diarrhea (diarrhea caused by feeling summer-dampness in summer), phlegm-heat cough, vomiting and epistaxis, carbuncle, swelling and sores, and so on. Psyllium is a water-inducing and dampness-permeating medicine, which is the whole grass of Psyllium or Psyllium. In the treatment of carbuncles and swellings, it can be taken internally, but it can also be applied externally by pounding the fresh herb. Psyllium is cold and slippery (meaning that the drug is cold and sweet in nature and has a slippery effect), so it is forbidden to be taken by those who have sunken yang qi, spermatorrhea in kidney deficiency and those who do not have internal dampness and heat. Pericarpium Citri Reticulatae has the effects of regulating qi and strengthening the spleen (regulating qi and strengthening the spleen), and drying dampness and resolving phlegm (removing phlegm from the body by drying dampness). It can be used clinically for symptoms such as distension and fullness in the chest and epigastric region, poor appetite, vomiting and diarrhea, and cough with excessive phlegm. Chenpi is warm and can help heat, so it should be used with caution for people with red tongue and little fluid and internal dampness and heat. It is easy to damage the vital energy by taking it for a long time, and you can’t eat raw, cold and sticky food during the period of using Chen Pi. Psyllium plus Chen Pi can also be used to make tea with boiled water, with expectorant, cough, asthma, refreshing, weight loss, etc., but should not be consumed for a long time to prevent adverse effects on the body. The use of Chinese medicine should be taken under the guidance of a physician.
