Onion
The bulb of the onion plant is a valued medicine as well as a popular vegetable. Onions have been cultivated for centuries. The species has been domesticated for so long that it is unknown in the wild; it is likely to have originated in Central Asia where related species grow today.
Bulbs are underground plant organs. Beneath the soil surface, the disclike stem of the onion plant develops roots and leaves that become swollen at the base to form a bulb. Papery outer leaves protect the fleshy bulb, which is an important starch reserve for the plant. Above ground, the hollow bluegreen leaves may reach 1m in length. The small, white to purple flowers are borne in a spherical inflorescence.
Species informationDistribution: Cosmopolitan
Habitat: Grow in a sunny position on well-drained soil
Form: Herb
Family: Liliaceae
Scientific name: Allium cepa L. (Alliaceae)
Onions are among the most-used medicinal plants in the United Kingdom. Their distinctive smell and eye watering effect are due to the presence of sulphur-containing molecules known as sulphoxides. These are broken down by enzymes into pungent volatile compounds when the onion is cut.
Onions are used in remedies to treat a variety of ailments; the most commonly documented uses are for respiratory ailments such as asthma, bronchitis and whooping cough.

Although a citizen of the U.S.A. , my ancestors originally migrated from the U.K. , Ireland , and Scotland (Early 18th century , and mid 19th century). A practice and a story , which will soon fade to nothingness , which I recall from a very early age involves the use of onions as a prophylaxis against disease . During times of near epidermic disease (influenza and polio being but two examples) , family elders made sure that saucers containing onion slices were liberally positioned throughout the house . No single individual could remember the exact mechanism by which onion slices supposedly exerted their protective power , only that "It worked." , and "That's the way it's always been done ." . Recently I chanced to learn that during 17th century epidemics in London (cholera , salmonella , and the catch-all phrase "the vapors") , the deceased of families could not be buried in a timely fashion due to the shear number of dead . Consequently the bodies of dead family members were kept in the parlor (hence "pallor") , and surrounded by onion slices which were used to help mask the odor of early putrefaction . I suspect that although over the ensuing three centuries , the practice of using onion slices has continued , although the true origin of the "beneficial nature" has long since been forgotten . While trying to glean additional information on the subject , I "discovered" your wonderful "Channel 4" site . The words "onion" and "deodorant" were found linked on a "MedicineChest" comment , so I hope that you'll permit a bit of relevant tangential thought on my part - this involving "underarm deodorants" as follows : During an earlier stage of my life , I'd very much enjoyed communal living ... an extended family of dearly loved friends living together under one roof . It occurred to me that each person has a natural odor that is unique to that person alone , and that the individuals natural odor is both a means of identification and communication - Identification as an analogous function within many non-human communities , and communication as a function perhaps best exemplified by the sexually stereotypical noun "pheromone" . This conclusion has been drawn with the assumption that our human bodies are bathed or showered on a daily basis - otherwise "all bets are off" . It appears , or rather "smells" , that the bodies of our species have two distinct types of odor . One is the purely natural "primary" as described , and one is the odor that results from the bacterial action involving the break-down of the "primary's" lipid (waxy or "fatty") component . Although our bodies do indeed have a profoundly intense natural odor , I'm by no means alone in professing that as long as one maintains daily "soap and water" hygiene , our natural "scent" is in no way offensive ! That being said , I'll not get into the scientific data which oft times tends to suggest that the use of "chemical masks" is not in our collective "best interest" when viewed from a health-wise perspective , nor will I speculate on the socioeconomic drives behind the multi-billion pound/dollar industry that actually is so very effective in reduceing our natural ability to recognize and process information . Just as a suggestion applicable to both the established social norms within the workplace , and the bottom line "amount due" of the post-shopping list tab , I've found that a cupped handful of inexpensive rubbing alcohol , applied to the underarms after the daily shower , eliminates consciously detectable odor , while leaving the subliminal door open (You might be amazed at the new-found "awareness".) ... and sparing the bodily contact of a fairly lengthy list of chemicals which have been linked to everything from acne to Alzheimer's ! Also , while researching the natural and supernatural lore of the Scottish Highlands , I very serendipitously encountered a compilation entitled "A Helen Adam Reader" by Kirstin Prevallet , which was published in 2007 . Although I don't recall any specific mention of onions , this magnificent volume does portray the works of the balladeer as a gifted storyteller who disseminates folk information , health and otherwise , with chilling effect . Although not exactly sure as to why , I did somehow find it relevant to the theme of tales unwritten being passed on through time . Apologies are offered for being so long-winded . Any thoughts on the topic are most welcome . Thank you ! walt
