Pinellia ternata

Pinellia ternata (Chinese: 半夏, Japanese: カラスビシャク), crow-dipper, is a plant that is native to China, Japan, and Korea. However, it also grows as an invasive weed in parts of Europe (Austria, Germany) and in North America (California, Ontario, the northeastern United States).[1][2] The leaves are trifoliate, and the flowers are of the spathe and spadix form that is typical of plants in the family Araceae.[3]

Traditional medicineEdit

This plant is toxic in raw form and must be processed.[citation needed] Pinellia ternata is known as the herb effective in removing dampness-phlegm, one of the causes of obesity in traditional Chinese medicine.[citation needed][5] One study found that high doses of Pinellia extract effects thermogenesis and fatty acid oxidation in Zucker rats.[4]
