Title: Are gourds poisonous, edible?
Answered by: Nan Hampton

QUESTION:

Are all the Gourds edible? How can I know which one is which? If it is not edible, is it poisonous? If not, what is stopping us from eating them?

ANSWER:

Since our expertise is with plants native to North America I can tell you about our native gourds.  Cucurbita foetidissima (buffalo gourd) is the species I am most familiar with since it occurs locally.  There are four native species of Cucurbita that are called gourds: Cucurbita foetidissima (buffalo gourd), Cucurbita digitata (fingerleaf gourd), C. palmata (coyote gourd) and the endangered C. okeechobeensis (Okeechobee gourd). None of my favorite toxic plant databases (Poisonous Plants of North Carolina, Canadian Poisonous Plants Information System, Cornell University Plants Poisonous to Livestock or other Animals or Texas Toxic Plant Database lists any species of Cucurbita.  Delena Tull (Edible and Useful Plants of Texas and the Southwest) says about the buffalo gourd (C. foetidissima):  "Though related to the edible squashes, the fetid odor and the extremely bitter taste of the buffalo gourd make the fruit inedible."  However, archeological investigations show that native Americans used the seeds as food.  They also used the green fruit and roots as a detergent and the dried fruits as a rattle.  Although javelinas dig up and eat the bitter root and coyotes, porcupines and humans eat the seeds, apparently no one eats the fruits.

There are two other native North American plants that have a fruit called a gourd—Ibervillea lindheimeri (balsam gourd) and Melothria pendula (speckled gourd)—but these fruits are very small and probably don't look like what you think of as a gourd.  Poisonous Plants of North Carolina lists M. pendula as causing "only low toxicity if eaten"—its berries act as a strong laxative.  None of the toxic plant databases above lists I. lindheimeri.

You can read about the gourds of other places (Africa, South America) and their many uses on Wikipedia. This article says that very few gourds are used for food, but there are some Asian species that are consumed.
