"The pistillate heads consist of two pistillate flowers surrounded by a spiny involucre. Upon fruiting, these two flowers ripen into two brown to black achenes and they are completely enveloped by the involucre, which becomes a bur. The bur, being buoyant, easily disperses in the water for plants growing along waterways. However, the bur, with its hooked projections, | "The pistillate heads consist of two pistillate flowers surrounded by a spiny involucre.

+ | The plant contains carboxyatractyloside (CATR), which leads to an infrequent but often fatal form of herbal poisoning. "Both ATR and CATR inhibit the transport of ADP across the mitochondrial membrane, preventing the synthesis of ATP and leading to failure in gluconeogenesis and cell death because of energy starvation... Poisoning in humans may present with either acute hepatic or renal pathology and it is possible that there is a second, different mechanism of toxicity to the hepatocyte. Atractyloside in large amounts gives rise to massive necrosis, but in vitro studies have shown that at lower doses cells progress to apoptosis." | ||

"The ethanol extract of X. strumarium (EXS) was fractionated on the basis of polarity. Among the different fractions, the n-butanol fraction showed the highest anti-inflammatory activity in the croton-oil-induced ear edema test and furthermore reduced the number of writhings induced by acetic acid in mice in a dose-dependent manner... The isolated caffeoylquinic acids could partially explain the antinociceptive effect of X. strumarium polar extract." | "The ethanol extract of X. strumarium (EXS) was fractionated on the basis of polarity.
