Although it has been known for more than a century that plants are able to extract appreciable amounts of the relatively insoluble compounds of barium contained in soils, very little scientific investigation has been made to determine whether or not the compounds of this element have any specific function in the vegetable economy. Because compounds of barium are poisonous when taken into the an...

In the present study, we reviewed food poisoning data published by the Ministry of Health, Labour and Welfare of Japan from 1961 to 2010 in Japan to analyze the trends of plant toxin food poisonings (PTFPs). The annual number of incidents of PTFPs has gradually increased since 1995. PTFPs were predominantly caused by Datura spp., Veratrum spp. and Aconitum spp. Although PTFPs frequently occurre...

In most cases where livestock are poisoned by plants in a range setting, there is more than one potential poisonous plant in the same area. Two poisonous plants that are often found growing simultaneously in the same location are death camas (Zigadenus spp.) and low larkspur (Delphinium spp.). Sheep are known to be susceptible to death camas poisoning while they are thought to be resistant to l...

Toxic plants such as Delphinium spp. (i.e., larkspur) are a significant cause of livestock losses worldwide. Correctly determining the causative agent responsible for the death of an animal, whether by disease, poisonous plant, or other means, is critical in developing strategies to prevent future losses. The objective of this study was to develop an alternative diagnostic tool to microscopy an...

A pure sodium chloride solution, at the concentration in which this salt exists in sea-water, may be poisonous to marine organisms, as was first proven by Loeb,’ who found that the young of a marine fish (Fundulus) soon die in y to F solution of sodium chloride. That death is due to the poisonous action of the sodium chloride, and not merely to the absence of other constituents of the sea-water...

the production and proper utilization of medicinal plants in natural habitats need to review and identify the natural conditions and climate of the habitat of these plants and separating them from harmful and poisonous plants. the current study was aimed to introduce and determine the distribution of medicinal plants from lamiaceae family in mazandaran province as well as the introduction of na...
