Angelica (Angelica archangelica or Angelica sinensis)

DESCRIPTION

Used in China for thousands of years as an important medicine, angelica exists in two varieties specific to Chinese and American regions. The American variety (Angelica archangelica) is regarded as safe by the FDA, and may be used for both external and internal purposes. It has become well known for its ability to soothe gastrointestinal upsets. Chinese angelica (Angelica sinensis) is also known as Dong Quai.

HERBAL USES

American angelica is known to be a carminative, an agent that relieves flatulence and gas, and to possess antispasmodic properties. It may also have moderate antibacterial and antifungal properties. Traditional uses of American angelica have not been investigated and appear unrelated to its known components.
