What is Roghan Kadu?

Roghan Kadu is the Urdu/Persian name for pumpkin seed oil, a nutrient-dense oil cold-pressed from the seeds of Cucurbita pepo, a gourd cultivated across Asia, the Middle East, and Europe for thousands of years. In Ayurvedic and Unani medicine, it has long been used as a tonic for the urinary tract, kidneys, and skin. It gained particular prominence in traditional Styrian (Austrian) cooking and folk medicine, where it became known as 'green gold' for its striking dark color and therapeutic reputation.

How does Roghan Kadu work?

Pumpkin seed oil is thought to work through several complementary pathways. Its unique delta-7-sterols are thought to gently inhibit the conversion of testosterone to DHT (the hormone associated with prostate enlargement and male-pattern hair loss), without fully blocking the enzyme the way pharmaceutical drugs do. The oil's zinc content is believed to support testosterone regulation and immune function, while its anti-inflammatory fatty acids and carotenoids may help reduce tissue irritation in the bladder and prostate. Together, these proposed actions help explain its traditional use for both urinary symptoms and hormonal hair thinning, though robust clinical evidence confirming these effects in humans remains limited.

What forms does Roghan Kadu come in?

Therapeutic-grade Roghan Kadu is typically available as cold-pressed oil (dark green, unrefined, with a rich nutty flavor) or in softgel capsules for standardized dosing. Capsules are preferred for urinary and prostate protocols where consistent daily dosing matters. Culinary-grade oils from grocery stores may have reduced potency. For hair use, the oil is sometimes applied topically or taken orally alongside other botanicals like saw palmetto.

Where it comes from:

Pumpkin seeds have been used medicinally in the Americas, Middle East, and Central Europe for over 500 years. Native American healers used them for kidney and urinary complaints. Persian Unani physicians included 'Roghan Kadu' in formulations for the bladder and prostate. In 16th-century Styria (now Austria), pumpkin seed oil became so valued that laws reportedly prohibited its export. Broader interest in the oil for BPH and overactive bladder grew in the 1990s.

What does Roghan Kadu help with?

• Enlarged prostate (BPH): Roghan Kadu has traditionally been used to support urinary comfort in men experiencing symptoms associated with benign prostatic hyperplasia. In traditional practice, it has been used to address concerns such as weak urinary stream, a sensation of incomplete emptying, and frequent nighttime urination, possibly through its delta-7-sterols, which may modestly reduce DHT-driven prostate tissue growth and calm local inflammation. Evidence supporting these uses remains largely observational and preliminary.
• Overactive bladder and frequent urination: Beyond prostate-related concerns, Roghan Kadu has traditionally been used for overactive bladder symptoms in both men and women. Practitioners have long used it with the expectation that it may help reduce urgency, nighttime urination (nocturia), and involuntary leaks, possibly by soothing irritation in the bladder lining and supporting normal detrusor muscle tone. These observations are based largely on traditional use rather than confirmed clinical trials.
• Hair thinning and hair loss (men and women): Pumpkin seed oil has traditionally been used as a gentler natural option for androgenic hair loss. It is thought to modestly reduce DHT levels at the hair follicle, which may slow the miniaturization associated with pattern baldness and thinning. Regular oral use over several months has traditionally been associated with possible improvements in hair density, though well-controlled clinical evidence remains limited.
• Urinary tract health: Traditional Ayurvedic and Unani medicine has long used Roghan Kadu to tone and protect the urinary tract. Its constituent compounds are thought to possess anti-inflammatory and antimicrobial properties that may help reduce irritation and support the mucous lining of the bladder and urethra, though these effects have not been conclusively validated in clinical trials.
• Low testosterone support: Pumpkin seeds are among the richer plant sources of zinc, a mineral thought to be essential for testosterone production. The oil retains meaningful zinc content, and its phytosterols may also help preserve free testosterone by moderating DHT conversion. In traditional practice, it has been regarded as a gentle hormonal support, though it should not be considered a substitute for medically evaluated hormonal treatment.
• Menopausal urinary symptoms: Postmenopausal women experiencing bladder urgency, leakage, and increased urinary frequency have traditionally used pumpkin seed oil as a supportive remedy. The drop in estrogen after menopause can weaken pelvic floor and bladder tissue, and practitioners have long used this oil with the expectation that its anti-inflammatory compounds may offer some symptom relief. Available evidence for this use remains observational and preliminary rather than clinically confirmed.
• Scalp and skin health: Rich in vitamin E tocopherols and carotenoids, pumpkin seed oil has traditionally been used to help protect skin and scalp from oxidative stress when applied topically or consumed. It is thought to support a healthy scalp environment that may be conducive to hair growth, and it has a nourishing, non-comedogenic profile considered suitable for most skin types in traditional practice.
• Antioxidant and anti-inflammatory support: The carotenoids, tocopherols, and polyphenols in pumpkin seed oil are thought to contribute to a broad antioxidant effect throughout the body. In traditional practice, regular consumption has been associated with general support against oxidative stress and low-grade inflammation, though whether this translates to measurable reductions in chronic disease risk has not been established by clinical evidence.

What can Roghan Kadu help prevent?

• Progression of mild-to-moderate BPH symptoms
• Worsening of androgenic hair loss (early intervention)

Which foods are rich in Roghan Kadu?

1. Raw pumpkin seeds (pepitas)
2. Cold-pressed pumpkin seed oil (culinary)
3. Roasted pumpkin seeds
4. Whole pumpkin and squash flesh
5. Sunflower seeds

Practical Tips:

Pumpkin seed oil is the extracted form of naturally occurring compounds in pumpkin seeds. Eating whole or lightly roasted pepitas (about 30g/day) is the most food-forward way to get the same benefits. Pairing pumpkin seeds with zinc-rich foods like oysters or legumes further supports the testosterone-regulation and prostate-health pathways.

What are the side effects of Roghan Kadu?

• Mild stomach upset or loose stools (usually if taken on an empty stomach)
• Nausea (rare, typically dose-related)
• Mild headache (reported rarely)
• Allergic reaction (very rare; caution in those with known seed allergies)

Good to know:

Roghan Kadu has an excellent safety profile in both traditional and contemporary use. It is generally suitable for long-term use at recommended doses. Side effects are uncommon and mild.

How much Roghan Kadu should you take?

• Recommended daily: 320–1,000 mg of cold-pressed pumpkin seed oil extract daily (commonly used amounts are around 320 mg twice daily for BPH and overactive bladder). Culinary use: 1–2 tablespoons of whole seed oil daily.
• Best time of day: No strong preference; splitting into morning and evening doses mimics the commonly used dosing pattern.
• With or without food: Best taken with a meal — the healthy fats in the oil aid absorption of its fat-soluble compounds (Vitamin E, carotenoids), and food reduces the chance of stomach upset.
• Time to effect: Urinary and prostate symptoms: 4–8 weeks for noticeable improvement. Hair growth: 3–6 months of consistent use.
• How long to take it: Can be used long-term without cycling. Extended use over 3–12 months has generally been well tolerated with no safety concerns. Ongoing use is appropriate as a maintenance strategy for BPH or hair health.
