Ayapan (Eupatorium Triplinerve) Properties, Benefits & Dosage


Ayapana is an ornamental erect perennial herb with aromatic leaves that grows 20 to 30 cm high. The 5-8 cm long leaves are smooth, lanceolate, and borne on purple stems. It produces many flowering heads with about twenty pink flowers, which are 6 to 7 millimeters long. Ayapana is native to South America and can be found in the Amazon region of Brazil, Ecuador, Peru, and the three Guyanas. It has been introduced into the U.S. and can be found in Puerto Rico and Hawaii. It has naturalized in other tropical countries as well. Ayapana has three different Latin names (Ayapana triplinervis, Eupatorium ayapana, and E. triplinerve) but all three names refer to the same plant.

Ayapan is known as Vishalyakarni in Sanskrit and is considered an herb that heals wounds and controls blood clotting. The leaves and stem of Ayapana are indicated in bleeding diarrhea, bleeding piles, bleeding from the stomach or bleeding from any part of the body.
