普通菊蒿 - 它的歷史和用途

Artemisia vulgare (Tanecetum vulgare) is also known as common tansy, bitter button, cow tansy, or golden button. The Latin word "vulgare" means "ordinary". Native to temperate Europe and Asia. It has been introduced to other parts of the world, including North America. In hotter countries, it reproduces faster - self-seeding in light soil, rapidly increasing in size. The ancient Greeks were probably the first to cultivate it as a medicinal herb.

It is listed on the noxious weed list in many U.S. states.

Artichoke - its history and uses

toxicity

Many tansy varieties contain volatile oils that can cause contact dermatitis in sensitive individuals.

If taken internally, toxic metabolites are produced when the oil is broken down in the liver and digestive tract.

It is highly toxic to internal parasites, and herbalists have used tansy tea to ward off parasites for centuries. Tansy is an effective insecticide and is highly toxic to arthropods. Due to the presence of thujone, the US FDA restricts the use of tansy in alcoholic beverages and the final product must be thujone-free.

Tanacetum annuum is often confused with common tansy (Tanacetum vulgare), but the essential oil produced by the former is chemically completely different as it contains no thujone and high amounts of matriculene, which gives the oil its dark blue color, giving rise to its common name " Blue” Tansy Oil. Although some unscrupulous essential oil dealers claim to adulterate the very expensive blue tansy (Tanacetum annuum) oil with the much cheaper chrysanthemum essential oil, the color of chrysanthemum essential oil is never blue because it does not contain chamomile azulen ene. Therefore, high-thujone oils from chrysanthemums should never be called "blue tansy" oil, and any blue oil containing high amounts of thujone is an adulterated product.

The active ingredients of volatile oils include

  • 1,8-Cineole (1,8-Cineole is a toxin believed to protect plant leaves from attack by herbivores.)
  • trans-thujone
  • Camphor and
  • Myrtenol

Its content and proportion vary with seasons and plants.
