A British colony in the Atlantic Islands, comprising two principal islands, East Falkland and West Falkland. Its capital is Stanley. Discovered in 1592, it was not occupied until the French settled there briefly in 1764. Later the English settled there but were expelled by the Spanish in 1770. The Falklands were claimed by Argentina but were occupied in 1833 by the British who, after an April 1982 invasion by Argentina, regained them in June. The islands were named by British Captain John Strong in 1690 for the fifth Viscount Falkland who financed Strong's expedition. The Spanish name for the islands, Malvinas, is from the French Malouins, inhabitants of St. Malo who attempted to colonize the islands in 1764. (From Webster's New Geographical Dictionary, 1988, p389 & Room, Brewer's Dictionary of Names, 1992, p182)

The vital life force in the body, supposedly able to be regulated by acupuncture. It corresponds roughly to the Greek pneuma, the Latin spiritus, and the ancient Indian prana. The concept of life-breath or vital energy was formulated as an indication of the awareness of man, originally directed externally toward nature or society but later turned inward to the self or life within. (From Comparison between Concepts of Life-Breath in East and West, 15th International Symposium on the Comparative History of Medicine - East and West, August 26-September 3, 1990, Shizuoka, Japan, pp. ix-x)

They may lack biomedical explanations but as they become better researched some (PHYSICAL THERAPY MODALITIES; DIET; ACUPUNCTURE) become widely accepted whereas others (humors, radium therapy) quietly fade away, yet are important historical footnotes. Therapies are termed as Complementary when used in addition to conventional treatments and as Alternative when used instead of conventional treatment.

Oils which evaporate readily. The volatile oils occur in aromatic plants, to which they give odor and other characteristics. Most volatile oils consist of a mixture of two or more TERPENES or of a mixture of an eleoptene (the more volatile constituent of a volatile oil) with a stearopten (the more solid constituent). The synonym essential oils refers to the essence of a plant, as its perfume or scent, and not to its indispensability.
