Although many health benefits have been attributed to the use of pumpkin seed oil, clinical evidence only indicates its potential effectiveness in treating benign prostatic hyperplasia, or BPH, according to WebMD. Pumpkin, its seeds, and oil from the seeds have also been used to treat kidney and prostate problems.
The effectiveness of pumpkin and its derivatives in treating kidney and prostate problems is due to its effects on the body as a diuretic, states WebMD. Pumpkin seed oil has been used in many cultures as a food item. The oil provides a good source of monounsaturated fat and is often used for salad dressing, with recipes posted on websites such as Food.com.
Published studies by the National Institutes of Health indicate that the oil has been studied for its nutritional properties and other potential benefits. One study, published in 2014 in the journal Evidence Based Complementary and Alternative Medicine, indicates that the oil may be effective in treating hair loss for men. The dosing for pumpkin seed oil varies according to the benefits one seeks to gain from it, but WebMD puts the daily does at 480mg per day, and also suggests taking saw palmetto along with the oil. Whether using medicinally or for gustatory pleasure, it is important to consult the specific product's consumption guidelines.
