Progesterone (P4) is an endogenous steroid and progestogen sex hormone involved in the menstrual cycle, pregnancy, and embryogenesis of humans and other species. It belongs to a group of steroid hormones called the progestogens and is the major progestogen in the body. Progesterone has a variety of important functions in the body. It is also a crucial metabolic intermediate in the production of other endogenous steroids, including the sex hormones and the corticosteroids, and plays an important role in brain function as a neurosteroid.
Actaea racemosa, the black cohosh, black bugbane, black snakeroot, rattle-top, or fairy candle, is a species of flowering plant of the family Ranunculaceae. It is native to eastern North America from the extreme south of Ontario to central Georgia, and west to Missouri and Arkansas. It grows in a variety of woodland habitats, and is often found in small woodland openings.
Hot flashes are a form of flushing, often caused by the changing hormone levels that are characteristic of menopause. They are typically experienced as a feeling of intense heat with sweating and rapid heartbeat, and may typically last from two to 30 minutes for each occurrence.
Saponaria officinalis is a common perennial plant from the family Caryophyllaceae. This plant has many common names, including common soapwort, bouncing-bet, crow soap, wild sweet William, and soapweed. There are about 20 species of soapworts altogether.
Clintonia borealis is a species of flowering plant in the lily family Liliaceae. The specific epithet borealis means "of the north," which alludes to the fact that the species tends to thrive in the boreal forests of eastern Canada and northeastern United States.
Dioscorea communis or Tamus communis is a species of flowering plant in the yam family Dioscoreaceae and is commonly known as black bryony, lady's-seal or black bindweed.
Yam is the common name for some plant species in the genus Dioscorea that form edible tubers.
Dioscorea polystachya or Chinese yam, also called cinnamon-vine, is a species of flowering plant in the yam family. It is sometimes called Chinese potato or by its Korean name ma. It is also called huaishan in Mandarin and wàaih sāan in Cantonese.
Caulophyllum thalictroides, the blue cohosh, is a species of flowering plant in the Berberidaceae (barberry) family. It is a medium-tall perennial with blue berry-like fruits and bluish-green foliage. The common name cohosh is probably from an Algonquian word meaning "rough". The Greek-derived genus name Caulophyllum signifies "stem-leaf", while the specific name thalictroides references the similarity between the large highly divided, multiple-compound leaves of meadow-rues and those of blue cohosh.
Stellaria media, chickweed, is an annual flowering plant in the family Caryophyllaceae. It is native to Eurasia and naturalized throughout the world, where it is a weed of waste ground, farmland and gardens. It is sometimes grown as a salad crop or for poultry consumption.
Dioscorea bulbifera is a species of true yam in the yam family, Dioscoreaceae. It is native to Africa, Asia and northern Australia. It is widely cultivated and has become naturalized in many regions.
Diosgenin, a phytosteroid sapogenin, is the product of hydrolysis by acids, strong bases, or enzymes of saponins, extracted from the tubers of Dioscorea wild yam species, such as the Kokoro. It is also present in smaller amounts in a number of other species. The sugar-free (aglycone) product of such hydrolysis, diosgenin is used for the commercial synthesis of cortisone, pregnenolone, progesterone, and other steroid products.
Sarsasapogenin is a steroidal sapogenin, that is the aglycosidic portion of a plant saponin. It is named after sarsaparilla, a family of climbing plants found in subtropical regions. It was one of the first sapogenins to be identified, and the first spirostan steroid to be identified as such. The identification of the spirostan structure, with its ketone spiro acetal functionality, was fundamental in the development of the Marker degradation, which allowed the industrial production of progesterone and other sex hormones from plant steroids.
Wild yam is a common name for several plants and may refer to:
The Mexican barbasco trade was the trade of the diosgenin-rich yam species Dioscorea mexicana, Dioscorea floribunda and Dioscorea composita which emerged in Mexico in the 1950s as part of the Mexican steroid industry. The trade consisted in Mexican campesinos harvesting the root in the jungle, selling it to middlemen who brought it to processing plants where the root was fermented and the diosgenin extracted and sold to pharmaceutical companies such as Syntex who used it to produce synthetic hormones.
Smilax aristolochiifolia, also known as gray sarsaparilla, Mexican sarsaparilla, sarsaparilla, is a species in the genus Smilax and the family Smilacaceae, native to Mexico and Central America. It is widely used as traditional medicine to treat many symptoms.
Aletris obovata is a plant species native to the southeastern United States.
Phytosteroids, also known as plant steroids, are naturally occurring steroids that are found in plants. Examples include digoxin, digitoxin, diosgenin, and guggulsterone, as well as phytosterols like β-sitosterol and other phytoestrogens like isoflavones.
Dioscorea sericea is a type of climbing tuberous geophyte in the family Dioscoreaceae. It is native to Colombia and Peru.
Dioscorea hispida, also known as the Indian three-leaved yam, is a species of yam in the genus Dioscorea, native to South and Southeast Asia. Known to be poisonous when fresh, careful processing is required to render it edible.
