#Taccachantrieri

In Thailand’s shaded forest understories grows a plant steeped in both botanical mystery and cultural practice: Tacca chantrieri, locally known as Nerapusee Thai or the black bat flower. Its velvety petals resemble a bat in flight, capturing the imagination of herbalists and drawing attention from modern researchers as it sits at the intersection of folklore and pharmacology.

For generations, the rhizome of Nerapusee Thai has been a valued component in Thai folk medicine. Healers across regions—each with its own dialect and ritual—have used powdered or boiled extracts to address ailments from skin irritations and digestive issues to bites and fevers. The plant wears many local names, such as Ma Thon Lak in Chumphon and Wan Nang Khruan in Nakhon Si Thammarat, illustrating how rural communities weave food, healing, and spiritual belief into daily life. In Thai villages, the plant often sits at the boundary between practical use and protective ritual.

Among the lush, shaded understories of Thailand’s tropical forests grows a plant shrouded in both botanical intrigue and cultural tradition—the enigmatic Tacca chantrieri, known locally as “Nerapusee Thai,” or more vividly as the “black bat flower.” With striking purplish-black petals that mimic a bat in flight, this unusual plant has captured both the imaginations of herbalists and the attention of modern scientists, standing at the crossroads of folklore and pharmacology.
