Styrian Pumpkin Seed Oil: Delta-7-Sterols & 5-Alpha-Reductase
The Green-Gold Elixir of Styrian & Anatolian Fields
While ordinary field pumpkins produce seeds encased in tough white hulls, the botanical mutation Cucurbita pepo var. styriaca produces dark-green, hull-less seeds packed with a dichromatic, ruby-green lipid: Cold-Pressed Pumpkin Seed Oil (Balkabağı Çekirdeği Yağı).- The Unique $\Delta^7$-Phytosterol Suite: Unlike common plant oils which are dominated by $\Delta^5$-sterols ($\beta$-sitosterol), pumpkin seed oil contains rare $\Delta^7$-sterols ($\alpha$-spinasterol, $\Delta^7$-avenasterol, $\Delta^7$-stigmasterol).
- Inhibition of 5-$\alpha$-Reductase: These sterols competitively inhibit 5-$\alpha$-reductase, the enzyme responsible for converting circulating testosterone into potent dihydrotestosterone (DHT), supporting healthy prostatic tissue volume and relieving bladder outlet obstruction.
