Stemona Root Chinese Herb

Stemona Root (Bai Bu): A Moistening Herb for Coughs, Lung Dryness, and Parasites
Introduction
Stemona root, known as Bai Bu (百部) in Traditional Chinese Medicine (TCM), is a sweet and slightly bitter herb used primarily to stop coughing, moisten the Lungs, and expel parasites such as lice and pinworms. Unlike harsh cough suppressants, Bai Bu soothes the respiratory tract gently, making it suitable for both chronic and acute coughs—especially dry or deficiency-related ones.
What Is Stemona Root?
Bai Bu is the prepared root of the Stemona sessilifolia or Stemona japonica plant, traditionally dried and sliced for use in decoctions or powders. In TCM, it is classified as sweet, bitter, and slightly warm, and it enters the Lung meridian.
This herb is best known for its dual action of moistening the Lungs while also acting as an anti-parasitic remedy—unique among respiratory herbs. It can be used alone or in formulas for dry cough, tuberculosis-related cough, or itchy skin caused by lice infestations.
Health Benefits of Stemona Root
Stops Cough and Moistens the Lungs
Ideal for dry, stubborn coughs due to Lung yin deficiency, chronic bronchitis, or post-infection dryness.
Clears Lung Heat and Relieves Wheezing
Used for coughs with yellow phlegm or heat signs, although it is not overly cooling—making it balanced.
Kills Parasites and Relieves Itching
Applied externally for lice, scabies, or pinworms; also used in washes or powders for dermatological use.
Gentle Enough for Children or the Elderly
Its soft, moistening nature makes it suitable for more delicate constitutions with dryness or fatigue.

Are There Any Side Effects?
Stemona root is generally well tolerated, especially for short- to medium-term use. However, it may cause mild nausea or gastrointestinal upset in large doses. It should be avoided in cases of damp-cold cough with copious phlegm, as it is moistening and slightly warm.
Always consult a practitioner before long-term use or if combining with other strong medications.
