Hinahina or Hinahina kū kahakai Boraginaceae The variety is endemic to the Hawaiian Islands Oʻahu (Cultivated)

When the leaves of koʻokolau (Bidens spp.) were not available, the leaves of hinahina kū hakai were brewed as a tea and believed to be a tonic by early Hawaiians. Dried leaves were used in treatment of diabetes. Too, the leaves along with alena (Boerhavia spp.) were pounded together, water added, and drunk for curing pāʻaoʻao (childhood disease, with physical weakening), ʻea (thrush), and naeʻoikū (severe asthma).

The fragrant white flowers and the succulent leaves were used, providing a long-lived attractive lei by the ancient Hawaiians.
