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.

Angelica contains coumarins, which are predominantly
phototoxic to human skin. It is currently being investigated
whether coumarins are a health hazard and should be avoided
entirely. Angelica can increase sensitivity of the skin to
light.

Angelica may interfere with the antiarrhythmic
agent, quinidine, glucose elevating agents. Use with antidiabetic
drugs may require dose adjustments.
Avoid use with vasoconstrictors, such as
ephedrine, methoxamine, and phenylephrine. Combined use may
lead to severe Hypertension. Use with citrates may produce
erratic and unpredictable results.

action of antihypertensive, ganglionic, peripheral adrenergic
