teucrin a/teucrium

The hepatotoxicity of the herbal plant germander and that of one of its major furanoneoclerodane diterpenes, teucrin A, were investigated in mice. Teucrin A was found to cause the same midzonal hepatic necrosis as observed with extracts of the powedered plant material. Evidence that bioactivation of

Due to its liver toxicity, the medicinal use of germander (Teucrium chamaedrys L.) was banned in some countries. Nevertheless, alcoholic extracts are still permitted as flavour ingredients since they are fundamental in providing a bitter aromatic taste. Teucrin A represents the substance of major

Teucrium chamaedrys L. (Labiatae), a herb used to combat obesity, can occasionally cause hepatitis. All mutagenicity tests done were negative. After 13 weeks of administration by oral route in Sprague Dawley rats T. chamaedrys proved to be well tolerated at 0.056 g kg(-1) day(-1) (i.e. 0.4 mg kg(-1)

Teucrium species, such as germander, are rich in neo-clerodane diterpenoids and have been used in traditional folk medicine for their stimulant, diuretic, antipyretic and antiseptic properties. However, the furano neo-clerodane diterpenoids present in germander have been implicated in the in vivo

Teucrium chamaedrys L. is an aromatic and medicinal plant used as traditional medicine. Aerial parts of the plant material were dried and extracted with hexane-dichloromethane (extract 1), ethyl acetate-dichloromethane (extract 2) and methanol-dichloromethane (extract 3) in a ratio of 1:1 at rt

Mass spectrometric fragmentation data of neo-clerodane diterpenes are almost inexistent but they can prove helpful for the qualitative and quantitative analysis of these compounds as well as for the identification of unknown compounds belonging to this class of plant secondary metabolites.

Teucrium chamaedrys L. is a herbaceous plant common in European woods that has been used for many purposes for centuries. Recently, T. chamaedrys L. has become popular as a slimming decoction without any scientific proof of efficacy notwithstanding its well-known hepatotoxicity. Hydroalcoholic

OBJECTIVE Two recurrent cases of severe acute liver injury attributed to the use of a wild germander decoction, prepared with some variation in traditional method has been reported. The aim of the present study was to correlate the hepatotoxic effect observed in patients who consumed germander

Germander, a plant used in folk medicine, caused an epidemic of cytolytic hepatitis in France. In about half of these patients, a rechallenge caused early recurrence, suggesting an immunoallergic type of hepatitis. Teucrin A (TA) was found responsible for the hepatotoxicity via metabolic activation

Several herbal remedies have produced hepatitis in humans. The medicinal plant, germander, was recalled after its use as an adjuvant to slimming diets resulted in an epidemic of hepatitis in France. We studied the hepatotoxicity of germander in isolated rat hepatocytes. A crude fraction containing
