Aster Root Whole (Aster Tataricus)

Aster Root Whole (Aster tataricus), known in Traditional Chinese Medicine as Zi Wan (紫菀), is a warm, slightly bitter and sweet herb traditionally used to transform phlegm, moisten the lungs, and relieve cough. These whole, fibrous roots are carefully harvested and dried to retain their natural potency, making them ideal for decoctions and classic respiratory formulas.

Zi Wan is especially valued for its ability to ease chronic or lingering coughs, whether dry or productive, by moistening dryness and helping the body expel phlegm. It is often used in cases of lung deficiency, wind-cold invasion, or phlegm accumulation, and is frequently paired with other lung-supporting herbs such as Kuan Dong Hua (Coltsfoot Flower), Bai Bu (Stemona Root), and Xing Ren (Apricot Seed).

When decocted, Aster Root Whole produces a dark, earthy infusion with a mildly sweet, slightly bitter taste. It works well as part of formulas aimed at soothing irritated lungs, reducing coughing, and promoting clear breathing, especially in colder seasons or when dryness affects the respiratory tract.

Each batch of Aster Root Whole (Aster tataricus) is carefully selected, dried, and prepared to maintain traditional quality and herbal strength. Whether used alone or in combination with other herbs, Zi Wan offers a time-tested, balanced approach to supporting respiratory health and relieving persistent coughs.
