No, it is not a progestin. Btw. progestin is always synthetic and used in birth control pills or HRT medicines. Walnut leaves contain natural progesterone. It was discovered only recently (2010).

Leaves of the Common Walnut = Juglans regia (also called English Walnut), tree should not be confused with BLACK walnut = Juglans nigra hulls (antiparasitic), you are referring to! Black walnut is widely available in the US, but it is NOT the same like juglans regia which contains progesterone.

PS: Juglans regia is also used to treat cancer.

That's great news Peggy, you'll have to let us know the results. You know walnuts are considered a phytonutrient/phytosterol, For fertility men can go nuts for walnuts, lol.

Eating 2.5 ounces of walnuts a day -- a little more than half a cup -- for 12 weeks improved sperm quality in healthy young men, researchers report. Their study is part of a growing body of evidence that men’s dietary and lifestyle choices might affect their fertility.

The new study, funded in part by the California Walnut Commission, enrolled 117 men aged 21 to 35 who ate a typical Western diet.

Phytochemicals are sometimes referred to as phytonutrients and these terms are often used interchangeably. Phytochemicals exhibit diversified physiologic and pharmacologic effects. They have been found to inactivate cancer-causing substances, stimulate the immune system, protect the heart from disease, and help prevent cataracts. Phytochemicals promote human health by strengthening the human immune system and blood vessels, by fighting tumors, and through other activities. Many of these non-nutritive substances have potent biological activity and may help to lower risk for many chronic diseases. Soybeans contain a variety of phytochemicals and are the only food source with nutritionally significant amounts of one type of phytochemical called isoflavones.
