What Is Sheng Ma
Sheng Ma also known as Rhizoma Cimicifugae is the rhizome of Cimicifuga heracleifolia, Cimicifuga dahurica or Cimicifuga foetida, which is a perennial herb belonging to the family Ranunculaceae. It is a relatively practical and common Chinese herbal medicine, which first appeared in <Shennong Ben Cao Jing> in the late Western Han Dynasty (about 100 BC).
There are about 18 species of cimicifuga, which are distributed in temperate regions of the northern hemisphere. Among them, the more common ones are Cimicifuga heracleifolia, Cimicifuga dahurica, Cimicifuga foetida, and Cimicifuga racemosa.
Cimicifuga heracleifolia often grows in hillside grass or shrubs. They grow well in deep, fertile, well-drained sandy loam. They are distributed in the three northeastern provinces of China, North Korea, and Russia.
Cimicifuga dahurica often grows in mountain forest edge shrubs, hillside open forests, or grasslands between 300-1,200 meters above sea level. They are distributed in northern China, Mongolia, and Russia.
Cimicifuga foetida likes a warm and humid climate. They often grow in mountain forest edges, forests, or roadside grasses between 1,700-2,300 meters above sea level. They are distributed in China, Russia, North Korea, Mongolia, and other Asian countries.
Cimicifuga racemosa commonly black cohosh or Actaea racemosa is a medicinal plant native to North America. The extract of this plant can be made into herbal medicine and dietary supplements. Its chemical composition and biological activity are similar to Sheng Ma, and it is often used to treat the female menopausal syndrome.
In autumn, people gather the rhizomes of Cimicifuga heracleifolia, Cimicifuga dahurica or Cimicifuga foetida, remove impurities, and their fibrous roots, dry them in the sun, cut them into slices, use them directly, or stir-fry them with honey, and make them into Chinese herbal medicines.
