With the arrival of October, pumpkins invade grocery stores, doorsteps, and kitchens. From comforting recipes to the famous illuminated Halloween lanterns, they have become one of autumn's most iconic symbols.
Yet, behind their decorative role lies a fascinating history. Cultivated for over 7,500 years, the pumpkin is among the oldest cultivated plants in the world. Long before becoming a Halloween icon, it was a precious source of food and medicine for the indigenous peoples of America. Even today, its seeds and their oil attract considerable interest due to their many potential health benefits.
The Surprising Origins of the Halloween Pumpkin
In Ireland and Scotland, turnips and potatoes were once hollowed out to make lanterns intended to ward off evil spirits1.
When Irish immigrants arrived in North America, they discovered that pumpkins were much larger and easier to carve than the root vegetables used in their homeland. The pumpkin thus became the essential Halloween symbol we know today2.
A Plant Cultivated for Millennia
Originating from Central America and Mexico, pumpkins were cultivated more than 7,500 years ago3. Archaeological evidence indicates that the cultivation of its seeds dates back to at least 1400 BCE4.
Through exchanges between indigenous peoples, the pumpkin spread throughout North America, where it became an essential food source.
Some Indigenous nations integrated it into their daily lives for both its nutritional and medicinal qualities5.
The Pumpkin as a Medicinal Plant
Long before the advent of natural supplements, indigenous peoples used pumpkin seeds for therapeutic purposes. Several First Nations peoples notably prepared infusions and remedies to6:
Support urinary health
Promote fluid elimination
Relieve certain bladder conditions
Interestingly, many of these traditional uses are now the subject of scientific studies7.
The True Treasure of Pumpkin: Pumpkin Seed Oil
While pumpkin flesh is featured in autumn recipes, it is often its seeds that contain its most interesting compounds8.
Pumpkin seed oil is particularly rich in9:
Omega fatty acids10
Vitamin E (tocopherols)11
Plant sterols12
Squalene
Magnesium13
Antioxidants14
Bioactive polysaccharides15
This nutritional composition gives it a vast potential for health support.
A Valuable Ally for Prostate and Urinary Health
One of the most documented uses of pumpkin seed oil concerns the support of prostate health.
Research suggests that it could help reduce certain symptoms of benign prostatic hyperplasia (BPH) by limiting the conversion of testosterone to dihydrotestosterone (DHT), a hormone involved in increasing prostate volume16.
It is also being studied for its potential role in17:
Overactive bladder18
Frequent urges to urinate
Urinary comfort in men and women
These observations recall several uses already known in indigenous traditions.
Support for Cardiovascular Health
Pumpkin seed oil contains plant sterols that could contribute to maintaining healthy cholesterol levels19.
Interesting Anti-inflammatory Properties
Chronic inflammation is involved in many health problems20. Experimental studies have shown that pumpkin seed oil has significant anti-inflammatory properties21.
In some animal models, it has helped reduce arthritis symptoms with effectiveness comparable to certain anti-inflammatory drugs22.
Benefits for Skin and Hair
Autumn often marks the return of dry skin, sensitized by temperature changes23.
Thanks to its richness in squalene, a compound similar to oils naturally produced by the skin, pumpkin seed oil helps support24:
Skin hydration25
The skin's barrier function
The comfort of skin prone to eczema or psoriasis26
Emerging research also suggests a favorable effect on hair growth and the prevention of hair loss associated with androgen hormones27.
Supporting Sleep and Mood as Winter Approaches
As days shorten and the pace of life intensifies, pumpkin seed oil offers another interesting advantage: its natural tryptophan content28.
This amino acid participates in the production of serotonin, a neurotransmitter involved in29:
Sleep quality
Emotional balance
Stress management
Maintaining a Positive Mood
Its antioxidants, including beta-carotene, also contribute to supporting the lymphatic system and protecting against oxidative stress30.
Much More Than an Autumn Decoration
This Halloween, when carving your pumpkin or preparing your favorite autumn recipe, take a moment to appreciate the exceptional history behind this seasonal symbol. And while modern research is gradually confirming many of its traditional uses, one thing is already certain: the pumpkin is one of the oldest functional foods in our history, a true gift of autumn that continues to nourish and inspire generations.
