Pinellia Tuber Chinese Herb

Pinellia Tuber (Ban Xia): A Warming Herb for Phlegm, Nausea, and Digestive Support
Introduction
Pinellia tuber, known as Ban Xia (半夏) in Traditional Chinese Medicine (TCM), is a warming herb used to dry dampness, transform phlegm, and harmonize the stomach to relieve nausea and vomiting. It is widely valued for its ability to address phlegm-related conditions, such as cough, chest congestion, and digestive issues caused by dampness or spleen deficiency.
What Is Pinellia Tuber?
Ban Xia is the dried tuber of Pinellia ternata, a plant in the Araceae family. In TCM, it is classified as acrid, warm, and slightly toxic (in its raw form), entering the Spleen, Stomach, and Lung meridians. Prepared Ban Xia (treated to reduce toxicity) is commonly used to ensure safety and enhance its therapeutic effects. It excels at resolving phlegm, calming rebellious stomach qi, and dispersing stagnation.
