<p>Hao
Apocynaceae
Endemic to the Hawaiian Islands
Hawaiʻi Island (Cultivated)
</p><p>Early Hawaiians scraped the bark and mixed with its flowers in water. The medicine was drunk to aid in curing pāʻaoʻao (a childhood disease with physical weakening) and ʻea (thrush).
</p><p>The wood of hao is very hard. "Native Hawaiian Medicine--Volume III" by Kaluna M. Kaʻaiakamanu notes: "It is called Hao because of what it is like due to the hardness that can spoil an adze." Incidentally, the name for iron in Hawaiian is also hao.
