A major compound in pumpkin is cucurbitacin E, a triterpene with strong antioxidant and anti-inflammatory properties. It is mainly contained in the seeds and has been shown to inhibit cyclooxygenase-2, an inflammatory protein related to a number of health conditions, including Benign Prostatic Hyperplasia (BPH).
Other powerful anti-inflammatory compounds in pumpkin are selenium, Omega-3 fatty acids, and sterols, all of which also contribute to prevent cardiovascular diseases by reducing cholesterol levels and lowering blood pressure.
With its high levels of beta-carotene pumpkin offers protection against many diseases, as well as many of the degenerative aspects of aging, including skin damage and eyes health. Beta-carotene not only has a strong photo-protective action that helps prevent the damage caused by ultra violet radiation, but it also promote the natural formation of collagen.
Pumpkins are also rich in potassium, fiber, and vitamin C, and therefore help promote healthy heart and kidney function.
Pumpkin Side Effects

Varieties and Subspecies of Pumpkin
The three recognized subspecies of Cucurbita pepo are C. pepo subsp. fraterna, subsp. pepo, and subsp. texana. Within these, there are countless varieties and cultivars, many of which have been manmade and some of which have developed in the wild. The most commonly cultivated subspecies is pepo.
The origin of pumpkin is obscure and there is some debate, although it is generally thought to hail from somewhere in the Americas.

Historically, it has played an important role in healthcare. The Mayans applied the sap to burns, the Menominee people recognized and used the seeds for their diuretic properties, and European settlers created an effective worming remedy, by mixing the seeds with water, milk, or honey.
Today, the pumpkin is commonly associated with jack-o'-lanterns and the Halloween holiday, but it is also widely used as a culinary ingredient. China is the world's leading producer of pumpkins and squashes with seven million tonnes per year, and worldwide, a massive two million hectares of land is dedicated to growing them.
