The Efficacy and Function of Rhizoma Pinelliae Praeparatum

Pinellia (prepared) is a commonly used traditional Chinese medicinal herb, primarily employed in the treatment of respiratory conditions such as cough and excessive phlegm. Its main functions include resolving phlegm, relieving cough, reducing upward rushing qi, and aiding digestion. Pinellia contains various bioactive components, such as peimine and peimanol, which possess potent expectorant effects, helping to resolve phlegm and dampness and alleviate symptoms such as coughing and chest tightness. In traditional Chinese medicine, Pinellia is widely used to treat disorders caused by damp-phlegm, such as bronchitis, chronic cough, and vomiting. It can regulate stomach qi and relieve indigestion and loss of appetite caused by phlegm-dampness obstruction. Pinellia also exhibits certain anti-inflammatory properties, helping to reduce inflammatory responses and promote recovery. The use of Pinellia should be conducted under the guidance of a TCM practitioner, as it has certain irritant and toxic properties, and unprocessed Pinellia may cause adverse effects. It is typically decocted or processed into膏 (a膏-like preparation), and only after appropriate processing can it be used safely and effectively.
