Pumpkins are the harbingers of fall. Thoughts of them conjure jack-o-lanterns, pies; even a pumpkin spiced late comes to mind. Pumpkins are one of the most popular crops in the United States with 1.5 billion pounds taking up 75,000 acres of cultivated soil each year. There are several plants in the genus, squash, gourds, cantaloupes, and cucumbers. Pumpkins originated in America. Fragments of stems, seeds, and fruits have been identified and recovered from cliff dweller ruins in the southwestern United States. Some pumpkin varieties may have originated in Mexico and Central America, while others probably developed in Peru, Colombia, and Ecuador. Some of these pumpkin and squash varieties probably have been cultivated as long as maize (corn), since around 3500 B.C. The seeds are known as pepitas and are extracted for their nutritious oil, made into a “butter”, and roasted or dried and sold for whole consumption.


Pumpkin seed oil has appreciable amounts of essential fatty acids, 47% of linoleic acid (omega-6) and nearly 0.5% of alpha-linolenic acid (omega-3), which are the precursors of prostaglandins, which are hormone like substances that have a variety of functions like contraction and relaxation of smooth muscles, support normal blood pressure, pain and inflammatory response, in humans and animals. Pumpkin seeds also contain the antioxidant nutrients Zinc and Vitamin E, both known to support healthy prostate function.

Ecologically Harvested is a term that describes all herbs sold by Gaia Herbs that are not Certified Organic. Ecologically Harvested herbs include herbs that are harvested in their natural habitat, (i.e., wild harvested) according to specific guidelines for harvesting these herbs (i.e., away from roads and industry, as well as guidelines to avoid overharvesting). Our term, Ecologically Harvested, also includes herbs that are grown in managed woodland areas, fields designated for specific herbs, and herbs that are grown by indigenous growers, such as Kava Kava. All Ecologically Harvested herbs pass pesticide and heavy metal testing as well as microbial testing, prior to release.
