Pumpkin seeds, like all edible seeds, pack an immense nutritional and medicinal punch. After all, they contain future worlds within their compact structure. As Emerson said, "the creation of a thousand forests is within one acorn."
In order to prepare their "babies" for survival outside the pumpkin, Nature equips these seeds with an extremely dense source of organically-bound nutrients, including exceptionally high levels of key, health-promoting minerals.
For example, a one cup serving (64 grams) of pumpkin seeds has 44% daily value (DV) of zinc, 22% of copper, 42% magnesium, 16% manganese, 17% potassium, and enough iron (17% DV) to improve iron-deficiency associated anemia.
But beyond the obvious nutritional virtues of the seed, recent scientific investigations have revealed that pumpkin seed meal, as well as its pressed oil, may have great value in alleviating the following conditions:
Postmenopausal Symptoms: Women supplemented with 2,000 mg of pumpkin seed oil over the course of 12 weeks were found to have reduced blood pressure, increased HDL cholesterol, as well as reduction in the severity of hormone insufficiency associated symptoms, e.g. hot flash, headaches and join pain.[iii] Additional experimental research indicates that adverse cardiovascular changes associated with estrogen deficiency, such as blood pressure and lipid abnormalities, can be mitigated with pumpkin seed oil.

Calcium-Oxalate Kidney Stones: According to a study performed in 1987 and published in the American Journal of Clinical Nutrition, children with calcium-oxalate crystals in their urine responded favorably to the supplementation of their diet with pumpkin seeds.[v]
Cardiovascular and Liver Disease: A mixture of flaxseed and pumpkin seed was found to have heart-protective and liver-protective properties in an animal study from 2008 published in the Journal of Food Chemistry & Toxicology.[vi]
Drug & Chemical Toxicity: The protein isolate of pumpkin seed has been shown to alleviate acetaminophen (Tylenol) toxicity on the liver,[vii] and as methotrexate-induced small intestine damage in an animal model.[viii] It has also been studied to protect against carbon tetrachloride-induced liver injury.[ix]
Arthritis: Pumpkin seed oil was found to compare favorably with the NSAID drug indomethacin in an experimental model of arthritis, but without causing liver damage, in a study published in 1995 in the journal of Pharmacological Research.[x]
