Lau käne, named after my teacher Uncle Bill Kanekoa, is used in Hawaiian medicine internally for respiratory problems such as asthma, bronchitis, and emphysema. It has a very distinctive taste.
The leaves are edible and have a strong pungent taste. They can be cooked or used raw in salads.
Lau käne is used in South America for phlegm in the lungs, malaria, to improve digestion and for cancer. In Great Britain it is used for warts, and in both Argentina and Spain for scurvy.
Caution: May cause skin reactions if used topically
