leaf Special Features and Information

General Information

Hinahina (Artemisia spp.) belong the Aster or Sunflower family (Asteraceae). There are three native species of Artemisia endemic to the Hawaiian Islands: A. australis is found on the all the main islands; A. kauaiensis on Kauaʻi; and A. mauiensis on Haleakalā, Maui.

The genus Artemisia includes notables such as Absinth wormwood (Artemisia absinthium) used to infuse vermouth and absinthe; tarragon (A. dracunculus) used in cuisine; and several species of the ubiquitous sagebrush (Artemisia spp.) of the picturesque American west. [1] In Korean cooking, the common mugwort (A. vulgaris) is used to flavor sook-dok (rice cakes), soups and other dishes. [2]

Etymology

The genus name Artemisia is derived from Artemis, Greek goddess of the hunt, wife of King Mausolus.

The Latin specific epithet australis, southern, is in reference to the southern island continent originally known as Terra Australis, and now Australia.

Hawaiian Names:

The Hawaiian name hinahina means gray or grayish; ʻāhinahina, from ʻāhina, is gray, gray- or white-haired in reference to the plant color. The added kuahiwi means mountain, referring to it's mountain habitat.

Background Information

 

Early Hawaiian Use

Clothing (Royalty):

Early Hawaiians used hinahina to preserve feather cloaks from insect destruction when stored in calabashes (ʻumeke).

Medicinal:

The leaves were pounded for lung problems, asthma and pulmonary consumption without phelgm. Leaves, stalks and roots with other ingredients were pounded and used in a steam bath to treat high fevers. [3]

Modern Use

Potential use for lei or flower arrangements.
