About
Commelina madagascarica is a monocotyledonous, herbaceous plant in the dayflower family from Madagascar. It is commonly known as nifin'akanga in Madagascar, where it is used medicinally as an abortifacient, a galactogogue, and a treatment for conjunctivitis and acne. It is also used for ritual purposes in joro or ancestral invocation around the Lake Alaotra region.
It has delicate, richly blue flowers, narrow leaves, and bushy stems. Its roots are fibrous, fleshy, and fusiform. These roots, and the plant's buried rhizome, make it very resistant to prairie fires.
