Health Benefits of Pumpkin
The antioxidant and anti-inflammatory characteristics have given pumpkin many traditional medicinal uses, mainly:
- Reducing prostate gland enlargement. Pumpkin seeds have been shown to reduce symptoms of benign prostatic hyperplasia, thus improving aging men's quality of life.1
- Regulating blood sugar levels. Studies have shown that pumpkin seeds can lower blood sugar levels by delaying carbohydrate absorption.2
Treating common skin conditions. Pumpkin has been traditionally used to treat burns, sores, and blisters, as well as for healing wounds.
Promoting heart health. Because of their richness in omega-3 fatty acids, they contribute to keeping cholesterol levels in check. Also, a study has found that pumpkins help manage high blood pressure in postmenopausal women.3
Additionally, the vegetable is also recommended to relieve the symptoms of Irritable Bowel Syndrome (IBS). Initial studies have also revealed the beneficial effects of pumpkin on inducing sleep, while another trial has shown that pumpkin seed oil may benefit men with androgenetic alopecia.4,5
How It Works
The cucurbitacin in pumpkin seeds also helps repel intestinal worms.
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
No side effects or drug interactions have been reported regarding to regular consumption or proper therapeutic doses of pumpkin (Cucurbita pepo). However, the over-consumption of bitter-tasting squashes - with higher levels of cucurbitacin - may cause diarrhea and dehydration.
Pumpkin is not only low in calories and carbohydrates, but also provides good amounts of essential minerals, such as potassium, necessary for the optimal functioning of muscles, including cardiac and lung muscles. Potassium is also an electrolyte that regulates the balance of fluids within the body, closely interacting with sodium in order to maintain adequate blood pressure and pH as well as controlling nerve impulses.
Pumpkin also contains copper, a trace mineral that aids iron absorption. It is essential for the production and transport of blood cells as well as for maintaining healthy bones, blood vessels, nerves, and immune system.
However, the flesh of pumpkin is better known for being a great source of vitamin A (from beta-carotene). Vitamin A is essential for skin regeneration and strong bones, also promoting good eye health and preventing age-related degenerative diseases.
Additionally, the pumpkin fruit provides adequate amounts of vitamins C (ascorbic acid), B2 (riboflavin), and E (alpha-tocopherol) as well as small amounts of other minerals, such as iron, magnesium, and zinc.
100 grams of cooked pumpkin provide 20 calories, with 2% and 4% of the daily value for carbohydrates and dietary fiber, respectively.

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.
PUMPKIN IS THOUGHT TO BE ONE OF NORTH AMERICA'S MOST ANCIENT DOMESTICATED PLANTS, WITH THE OLDEST KNOWN LOCATIONS IN MEXICO CLOCKING IN AT ABOUT 10,000 YEARS AGO.
Archaeological evidence suggests that the Aztecs used to snack on pumpkin seeds, meaning their nutritious benefits have been of historical importance as well as their medicinal properties. 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.
