Three facts about pumpkin (Curcubita pepo) you may not know about

#1 Cucurbitacins are constituents found in some plants, one of which is Curcubita pepo. These constituents are lettered from A to T and depending on their configuration have been shown to inhibit proliferation of cells and induce apoptosis (programmed cell death). Because of this finding, some researchers are considering their potential use as a treatment to target cancer cells.

#2 Curcubita pepo seed extract was shown to improve symptoms related BPH, reduce growth of the tissue, and improve quality of life. One potential mechanism of action is by reduction of the enzyme named 5-alpha reductase. This enzyme is responsible for conversion of testosterone to DHT. DHT is primarily responsible for prostate cell growth. By partially inhibiting this pathway, you will expect to see a slower growth of prostate tissue.

In addition, 10g of pumpkin seed oil a day for 12 weeks reduced symptoms related to an overactive bladder not related to an enlarged prostate.
