The Efficacy and Functions of Huajuhong
Under normal circumstances, Citrus grandis (Huang Juhong) has functions such as regulating qi and strengthening the spleen, relieving cough and expelling phlegm, promoting digestion, anti-inflammatory and antibacterial effects, and regulating blood lipids. A detailed analysis is as follows:

1. Regulating Qi and Strengthening the Spleen: Huang Juhong helps regulate qi and widen the middle jiao, as well as dry dampness and resolve phlegm. It aids in regulating spleen and stomach functions, promoting transformation and transportation processes, and improving symptoms such as abdominal distension and indigestion caused by qi stagnation.
2. Relieving Cough and Expelling Phlegm: Huang Juhong contains a large amount of limonene, which can stimulate secretion from respiratory mucosa, dilute sputum, and facilitate expectoration. It is suitable for treating cough caused by colds, chronic cough, asthma, and similar symptoms.
3. Promoting Digestion: Huang Juhong promotes secretion of digestive fluids and enhances gastrointestinal motility, improving digestive function. It has a therapeutic effect on symptoms such as indigestion, food accumulation in children, vomiting, and hiccups.
4. Anti-inflammatory and Antibacterial Effects: The active ingredients in Huang Juhong possess anti-inflammatory and antibacterial properties, inhibiting bacterial growth and reproduction and reducing inflammatory responses. These properties are beneficial for treating various infectious diseases.
5. Regulating Blood Lipids: Huang Juhong achieves this effect by promoting blood circulation, lowering blood lipids, and regulating blood glucose levels. It serves as an auxiliary treatment for reducing hypertension, hyperlipidemia, and hyperglycemia.
However, it is important to note that the use of traditional Chinese medicine should be conducted under the guidance of a physician. Additionally, proper dosage must be observed to avoid excessive intake that may cause unnecessary physical burden.
