Welcome back to Plants as Medicine. It is snowing here in Beijing for the third time this year and I am hard at work designing a learning garden that will be dedicated to Autumn Reine. We will have a large variety of plants, primarily medicinal, from China and as much of the rest of the world as we can.
But today, spurred by some comments recently about Elecampane and the use of the Inula genus in Chinese medicine I will give you a little information about the different species and how they are used in Chinese medicine. Inula is a genus in the Asteraceae family with about 100 species native to Europe, Asia, and Africa. There are 17 species in China with 3 endemics, at least 9 of these are used as medicine.
Most Chinese herbalists are familiar with xuan fu hua (旋复花), (pictured above), which is represented by 2 species, I. japonica and I. britanica. These species (the flowers) are used treat phlegm and coughing, as well as retching. However the other 7 species are less known to most Chinese herbalists, particularly in the West.
One of these species is I. helenium (tu mu xiang 土木香), which is known as elecampane in Western herbal medicine. A complete monograph of this medicinal can be found in my first book, Western Herbs According to Traditional Chinese Medicine: A Practitioner’s Guide.
Inula cappa (bai niu dan 白牛胆), which may not actually be part of this genus according to botanical records but is listed in the Chinese literature as such. The entire plant is used medicinally and is considered acrid, sweet, slightly bitter and warm. It is used to expel wind and disperse cold, move qi and disinhibit dampness, and resolve toxins and resolve swelling. It is used for a variety of ailments including common cold, cough, wind-dampness impediment pain, diarrhea, water swelling, white vaginal discharge, etc.

Inula linariifolia (jin fei cao 金沸草) is a medicine first found in the Shen Nong Ben Cao Jing. This species grows throughout much of Central and Eastern China, north into Russia, Korea and even in Japan. Along with this species both I. japnica and I. britanica are used as this medicine.

It dispels wind-cold, transforms phlegm, stops coughing, and disperses swelling. It is used for wind-cold cough, phlegm panting, clove sores with swelling toxicity, and wind-dampness pain.
