+Tanacetum vulgare L. - syn.Chrysanthemum vulgare (L.) Bernh. - Asteraceae - tansy, golden buttons, **Rainfarn**
-tansy, golden buttons, **Rainfarn**
 Perennial herb, 0.40-1.50m high, native to Eurasia; leaves bipinnately divided, leaflets serrulate; flower heads 1cm across, without ray florets, disc florets yellow.
-Of tansy genotypes from Finland, 15 were well defined and five were mixed chemotypes. The most frequently found monoterpene in pentane extracts of the flowerheads was camphor, other compounds were camphene, 1,8-cineole, pinocamphone, chrysanthenyl acetate, bornyl acetate and isobornyl acetate. In 13 genotypes, camphor concentration exceeded 18.5% and in seven genotypes, camphor was less than 7.2%. Other chemotypes were rich in trans thujone, artemisia ketone, 1,8-cineole, or davadone-D. \\

+The essential oil yield from plants grown in Norway "...ranged between 0.35 and 1.90% (v/w) (average:  0.81%); the most abundant thujone plants were especially rich in EO volatiles (0.95%). On the basis of GC-MS data, seven chemotypes could be identified as follows:  A, α-thujone (two individuals); B, β-thujone (22); C, camphor (six); D, chrysanthenyl acetate/chrysanthenol (three); E, chrysanthenone (two); F, artemisia ketone/artemisia alcohol (three); and G, 1,8-cineole (two). The thujone chemotype was dominated by β-thujone (81%) associated with α-thujone, but tansy plants rich in α-thujone were also detected (61%)." \\

 "Several chemotypes of tansy exist, differing in the composition of their volatile oil (α-thujone, β-thujone, camphor-type etc.)... Tansy has proven anthelmintic, antimicrobial and choleretic activities that are confirmed in human studies. The sesquiterpene lactones may cause allergic reactions, while thujone is a known neurotoxin. The oil (and thujone) may cause abortion, vomitting, abdominal pain, rapid brathing, rapid heart beat, loss of consciousness and death." \\
