BOTANICAL NAME: Costus pictus Planta Insulina
CONTINENT: Neotropical

Costus in Puerto Rico known as "Insulin Plant". In March 2009 trip to PR, I found mature inflorescence without flowers, that was described by members of the Heliconia Society of Puerto Rico as being native in PR and commonly known as "Insulin Plant". It has flowered for me here and is identical in all respects to a plant I had received from two other sources previously, that I have referred to as Costus pictus "Red Stem" (PID7451). The nectar callus on the bracts is dark green, and nearly invisible on some older inflorescences.

This plant is widespread on the island of Puerto Rico and I have tried to determine whether or not it is native there. The concensus is that it is an exotic plant, introduced to Puerto Rico many years ago. There apparently are no Costus species that are native to the island. From communication with Dr. Jannette Gavillan of the University of Puerto Rico at Cayey the plant is known as the "insulin plant" also in the Dominican Republic and the Yucatan of Mexico which may be its native origins.

This plant has been promoted as a medicinal plant in India. Also used as an insulin replacement is the species "Costus igneus" (Chamaecostus cuspidatus) and there is a National Institute of Health study at

Type 2 diabetes is a chronic disease in which the body?s insulin is notproperly released or does not interact correctly with its receptor. Type 2 diabetes is oneof the more common chronic diseases in Puerto Rico. People with Type 2 diabetes cancontrol the glucose levels by different methods such as: the use of oral hypoglycemicdrugs and exercise, or the combination of a controlled diet on the use of medicinalplants. In Puerto Rico some people use the plant commonly known as insulin plant as ahomemade remedy to decrease the glucose levels. In this investigation we willdetermine if the insulin plant has any quantifiable hypoglycemic effects. We will useaqueous, organic and other homemade extracts methods and test their effects onglucose levels in tissue culture cells.

R3172 is a collection from the farm of Sergio Tejedor, located near Jayuya in the cord. central of Puerto Rico. Sergio told me this plant had been growing naturally on his farm for as long as he could remember and he believed it was already there when his grandfather purchased the property. He and several other HSPR members believe the plant to be native to Puerto Rico, but apparently it is not, based on several other sources. It may have been introduced by indigenous people hundreds of years ago.
