What side effects this plant can have?
This plant can cause severe health complications including hepatic function failure, jaundice, metabolic toxification in the liver, rheumatoid arthritis, and scarlet fever. Consumption of the plant leads to dangerous metabolic toxification in the liver that disrupts normal chemical processes. This internal damage often results in hepatic function failure and the visible yellowing of the skin known as jaundice. Furthermore, individuals may experience systemic inflammatory issues such as rheumatoid arthritis. Some cases also involve the onset of symptoms similar to scarlet fever.
According to a study published by "Journal of food science", Ligularia fischeri var. spiciformis Nakai is an edible medicinal herb used to treat jaundice, scarlet fever, rheumatoid arthritis, and hepatic function failure. Using an on-line HPLC-ABTS screening system that measures absorbance at 734 nm, researchers detected 4 major antioxidant compounds in the plant's leaves. These 4 isomers, identified as 5-CQA, 3,4-DCQA, 3,5-DCQA, and 4,5-DCQA, comprise over 10% of the dried leaves. The ethanol extract derived from these caffeoylquinic acids showed 94% antioxidant activity. While 3,4-DCQA contained the strongest antioxidant activity, 3,5-DCQA had the highest radical scavenging capacity because it was the most abundant compound.
