Gouania domingensis Blanco
Gouania microcarpa Rolfe
Gouania retinaria DC.
Retinaria scandens Gaertn.
Common Name: Litiran
Litiran is a climbing shrub.
The roots are gathered from the wild and used locally as a substitute for soap. The leaves have local medicinal uses.
The bark contains saponins and is used to stupefy fish in rivers[
]. Although poisonous, saponins are poorly absorbed by the human body and so most pass through without harm. Saponins are quite bitter and can be found in many common foods such as some beans. They can be removed by carefully leaching in running water. Thorough cooking, and perhaps changing the cooking water once, will also normally remove most of them. However, it is not advisable to eat large quantities of food that contain saponins. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish[
