Biological Activities
Teucrium canadense is a plant species known to possess hepatotoxic properties due to the presence of specific diterpenes. This toxicity poses a significant public health risk when the plant is used as an adulterant in herbal products like skullcap. Research indicates that distinguishing between these species is essential for ensuring consumer safety in the herbal supplement market. Scientists can utilize chromatographic profiling to identify these dangerous contaminants even when they are present in very low concentrations. By detecting markers such as phenylethanoids, manufacturers can effectively prevent the accidental inclusion of this harmful plant in medicinal mixtures.
