Angelica Botanical: Angelica Archangelica (LINN.) Family: N.O. Umbelliferae Parts Used---root, leaves, seeds. Uses---Angelica is largely used in the grocery trade, as well as for medicine, and is a popular flavouring for confectionery and liqueurs. The appreciation of its unique flavour was established in ancient times when saccharin matter was extremely rare. The use of the sweetmeat may probably have originated from the belief that the plant possessed the power of averting or expelling pestilence.
