About
Dactylorhiza viridis, the frog orchid, is a species of flowering plant in the orchid family Orchidaceae. It has also been treated as the only species Coeloglossum viride of the monotypic genus Coeloglossum.
Safety
The chemistry of a variety that has been known as bracteatum is complex, featuring a wealth of bioactive constituents, at least seven of which are peculiar to the plant. Known compounds found thus far to be present are 4-hydroxybenzaldehyde, 4-hydroxybenzyl alcohol (=Gastrodigenin), 4,4'-dihydroxydibenzyl ether, 4,4'-dihydroxydiphenylmethane (see Xenoestrogen), 4-(4-hydroxybenzyloxy)benzyl alcohol, gastrodin, quercetin-3,7-diglucoside (see Flavonol glycoside), thymidine, loroglossin, militarine, dactylorhin A, dactylorhin B, β-Sitosterol and daucosterol.
Where it grows
Dactylorhiza viridis has a wide distribution across the cooler parts of the Northern Hemisphere, covering much of Europe, non-tropical Asia (Russia, Japan, China, the upper Himalayas, etc.), much of Canada and parts of the United States (Alaska, Northeast, the Appalachians, Great Lakes Region, Northern Great Plains, and Rocky Mountains). It is typically found growing in moist, rich soil in wet meadows, moist or wet deciduous woods and thickets, and is frequently found on steep slopes.
