Mexican Barbasco Trade
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. History Scientific discovery of medicinal properties The trade started when Russell Marker, a chemist looking for a plant source from which to extract diosgenin and saponin, traveled to Veracruz looking for the yam ''Dioscorea mexicana'' which he suspected might be suitable. He hired two Mexican campesinos to bring him exemplars of the tuber. When he discovered that the root was indeed a significant source of diosgenin he established Syntex, the first Mexican fine che ...

Dioscorea Mexicana
''Dioscorea mexicana'', Mexican yam or ''cabeza de negro'' is a species of yam in the genus ''Dioscorea''. ''Dioscorea mexicana'' is a caudiciform dioscorea having either a partly to completely above-ground dome-shaped caudex with a thick, woody outer layer up to 3 feet (90 cm) in diameter and 8–10 inches (20 to 25 cm) in height. The caudex of ''D. mexicana'' is divided into regular polygonal plates that become protuberant with age, and separated by deep fissures. The vigorous annual vines which may reach 30 feet (9 m) long before dying back in winter, that grow up from the caudex, bear heart-shaped leaves. ''Dioscorea mexicana'' ranges from the state of San Luis Potosí in northeastern Mexico south to Panama. It is notable for its production of diosgenin, which is a precursor for the synthesis of hormones such as progesterone. Russell Marker developed the extraction and manufacture of hormones from ''D. mexicana'' at Syntex. Later the Mexican barbasco trade fo ...

Addison's Disease
Addison's disease, also known as primary adrenal insufficiency, is a rare long-term endocrine disorder characterized by inadequate production of the steroid hormones cortisol and aldosterone by the two outer layers of the cells of the adrenal glands (adrenal cortex), causing adrenal insufficiency. Symptoms generally come on slowly and insidiously and may include abdominal pain and gastrointestinal abnormalities, weakness, and weight loss. Darkening of the skin in certain areas may also occur. Under certain circumstances, an adrenal crisis may occur with low blood pressure, vomiting, lower back pain, and loss of consciousness. Mood changes may also occur. Rapid onset of symptoms indicates acute adrenal failure which is a serious and emergent condition. An adrenal crisis can be triggered by stress, such as from an injury, surgery, or infection. Addison's disease arises from problems with the adrenal gland such that not enough of the steroid hormone cortisol and possibly aldo ...

Debt Peonage
Debt bondage, also known as debt slavery, bonded labour, or peonage, is the pledge of a person's services as security for the repayment for a debt or other obligation. Where the terms of the repayment are not clearly or reasonably stated, the person who holds the debt has thus some control over the laborer, whose freedom depends on the undefined debt repayment. The services required to repay the debt may be undefined, and the services' duration may be undefined, thus allowing the person supposedly owed the debt to demand services indefinitely. Debt bondage can be passed on from generation to generation. Currently, debt bondage is the most common method of enslavement with an estimated 8.1 million people bonded to labour illegally as cited by the International Labour Organization in 2005. Debt bondage has been described by the United Nations as a form of "modern day slavery" and the Supplementary Convention on the Abolition of Slavery seeks to abolish the practice.Article 1(a) of ...

Abortifacient
An abortifacient ("that which will cause a miscarriage" from Latin: ''abortus'' "miscarriage" and '' faciens'' "making") is a substance that induces abortion. This is a nonspecific term which may refer to any number of substances or medications, ranging from herbs to prescription medications. Common abortifacients used in performing medical abortions include mifepristone, which is typically used in conjunction with misoprostol in a two-step approach. Synthetic oxytocin, which is routinely used safely during term labor, is also commonly used to induce abortion in the second or third trimester. For thousands of years writers in many parts of the world have described and recommended herbal abortifacients to women who seek to terminate a pregnancy, although their use may carry risks to the health of the woman. Medications Because "abortifacient" is a broad term used to describe a substance's effects on pregnancy, there is a wide range of drugs that can be described as abortifac ...

Internal classification Egland and Bartholomew (1978) established fourteen Chinantec languages on the basis of 80% mutual intelligibility. ''Ethnologue'' found that one that had not been adequately compared (Tlaltepusco) was not distinct, but split another (Lalana from Tepinapa).
