What traditional systems uses this plant?
This plant, Cucurbita maxima, has been utilized across diverse global cultures for centuries as both a nutritional staple and a medicinal resource. In Iranian traditional medicine, the seeds and flesh are often employed to treat various ailments and balance bodily humors. Historical practitioners in many regions utilized the plant's seeds specifically for their antiparasitic properties to combat intestinal worms. Beyond its medicinal applications, the large fruits provided essential vitamins and calories to agrarian societies throughout the Americas and beyond. These traditional systems demonstrate a sophisticated understanding of the plant's diverse bioactive compounds.
According to a study published by "Journal of ethnopharmacology", pumpkin seeds are categorized as having a cold temperament according to the basic concepts of Iranian traditional medicine. In experiments involving 42 male Wistar rats, diets containing 10% seeds were used to observe effects over 24 hours and 7 days. On the 7th day, the pumpkin seed-fed group showed a significant increase in corticosterone levels. These temperature characteristics suggest that cold temperament seeds may decrease the body's energy metabolism.

What are the pharmacological activities of Cucurbita maxima?
This plant has diverse pharmacological activities including anti-cancer, anti-inflammatory, anti-diabetic, anti-oxidant, and anti-helmintic properties. Its high concentration of bioactive compounds helps neutralize free radicals to provide significant anti-oxidant protection to cells. These chemical constituents also work to suppress inflammation and regulate blood glucose levels to assist in anti-diabetic management. Furthermore, certain extracts demonstrate potential in inhibiting tumor growth and acting as an anti-cancer agent. Finally, the plant possesses anti-helmintic qualities that allow it to combat various parasitic worm infections.
According to a study published by "British journal of cancer", Cuc IIa is an active component that shows different structural modifications from other Cuc derivatives. This substance exhibits anti-cancer potential in addition to its conspicuous anti-bacterial and anti-inflammatory activity. It induces the irreversible clustering of filamentous actin and arrests the cell cycle by increasing G2/M populations. The component results in reduced phospho-Histone H3 and markedly increased cleavage of poly-(ADP-ribose) polymerase or PARP. Cuc IIa suppresses cancer cell expansion by disrupting the actin cytoskeleton and directing the cell to undergo PARP-mediated apoptosis through the inhibition of survivin downstream of JAK2/STAT3.
The primary pharmacological activities of this plant are shown in the list below.
- anti-cancer
- anti-inflammatory
- anti-oxidant
- anti-diabetic
- anti-helmintic
What medicinal compounds this plant contains?
This plant contains carotenoids, flavonoids, phenolic compounds, polyunsaturated fatty acids (PUFAs), and tocopherols that contribute to its diverse medicinal properties. The carotenoids and flavonoids serve as potent antioxidants that help protect cells from oxidative stress and inflammation. Phenolic compounds within the plant provide additional bioactive benefits through their ability to neutralize free radicals. The presence of polyunsaturated fatty acids (PUFAs) supports cardiovascular health and essential cellular functions. Additionally, tocopherols act as vital vitamin E sources that further enhance the plant's overall nutritional and therapeutic profile.
According to a study published by "Foods (Basel, Switzerland)", Cucurbita maxima cultivars such as 'Show Winner' and 'Pink Jumbo Banana' contain promising medicinal compounds for nutraceutical applications.
