Sheng half-sia has the effects of drying dampness and resolving phlegm (expelling dampness by drying dampness and dissolving phlegm), eliminating lumps and dispersing knots (eliminating knots in the body), etc. There is no indication that it can be used to treat hydrocephalus. However, if hydrocephalus is present, it can be treated with medication as prescribed by the doctor. Sheng Hanxia is a Chinese medicine that can dry dampness, dissolve phlegm, lower the rebellious Qi in the stomach, stop vomiting, dissipate the Qi in the stomach, and disperse knots. It is pungent in taste, warm in nature, and poisonous in nature, and is classified as belonging to the spleen meridian, the stomach meridian, and the lung meridian. It is mainly used to treat cough and asthma caused by phlegm-drink stagnation, palpitations, dizziness, prunus qi (similar to pharyngeal dysphagia), headache, vomiting, regurgitation, carbuncle and phlegm nuclei (lumps swollen up like nuclei under the skin), and chest and epigastric plumpness (a feeling of fullness and stuffiness in the chest and abdomen), and so on. Those who are allergic to Shengmianxia are prohibited from taking it, and when taking Shengmianxia, it should not be taken together with aconite-type herbs. If the dosage of Radix et Rhizoma Pinelliae is too large, toxicity may occur, so caution should be exercised when taking the medicine. Shengmianxia does not have the effect of treating hydrocephalus. When hydrocephalus patients suffer from dizziness, coughing and wheezing caused by phlegm-drink congestion and stagnation, they can take Shengmianxia under the guidance of a professional Chinese medicine practitioner for treatment. The effect of a single medicine is limited, if the symptoms are more serious, please go to the hospital in time to see a doctor, do not delay the condition.
