THE ETHNOMEDICAL USE OF BLACK DRINK TO TREAT IRON DEFICIENCY ANEMIA IN BASTIMENTOS, PANAMA by CASSANDRA NELSON DOOLEY (Under the Direction of Diane K. Hartle) ABSTRACT Iron deficiency anemia (IDA) is the most common nutritional deficiency in the world and intestinal parasites are estimated to be responsible for 30-57% of IDA cases (Yip 2001; Stoltzfus 1997). With an iron-poor diet and the high incidence of blood-sucking helminthes, the people in Bastimentos, Panama struggle with IDA. Black Drink is the ethnopharmacological answer to these pathologies. It is prepared with juice from Citrus aurantifolia, a cast iron vessel, and three biologically active plants, Stachytarpheta jamaicensis, Hyptis suaveolens, and Senna spp. The iron content and the pharmacognosy of the plants used to prepare Black Drink are investigated here. Analysis of Black Drink revealed an iron content of 2.5% indicating a dose of iron comparable to that prescribed by U.S. physicians for IDA. In Bastimentos, Panama, Black Drink is an effective, affordable, two-prong strategy for the treatment of IDA, intestinal parasite burdens, and is congruent with the popular therapeutic traditions.

I learned that it is possible to be a true wise woman without ever attending school, learning to read, or write. This work is in honor of her abilities as a healer and a botanist. iv ACKNOWLEDGEMENTS I want to acknowledge my mentors from the ICBG-Maya, who gave me my first opportunity to work in the field of ethnobotany, medicinal plants, and drug discovery: Dr. Dave Puett, Dr. Elois Ann Berlin, and Dr. Brent Berlin. Next, I thank Fulbright for the chance to independently create an ethnobotanical study in Bocas del Toro, Panama. The Nutraceutical Laboratories, my major professor, Dr. Diane Hartle, and Dr. Greenspan welcomed me warmly, challenged me in the field of pharmacology, and shared enthusiasm for natural products and countless laughs with me. Finally, my friends and family provided the reassurance and emotional support to persist when I questioned my own abilities. I am deeply grateful to all of these people for their contributions to my success. v TABLE OF CONTENTS Page

Bastimentos is an Afro- Caribbean community and Salt Creek is an indigenous Ngawbe group with their own language. Three hundred botanical specimens were collected and identified at the Autonomous University of Chiriqui (UNACHI), and were deposited at the herbariums at UNACHI, University of Panama, and The University of Georgia. International partners are Botanists,
