False shamrock is a weed or an ornamental plant that normally will not be ingested by mistake. It is not dangerous to touch it. It is a toxic plant that contains oxalic acid but is less toxic. Consuming in small quantities will not affect health, but long-term consumption will affect the body's calcium supply, leading to inadequate nutrition. The amount of oxalic acid will decrease after its leaves are cooked. If people with rheumatism, arthritis, gout, kidney stones, or hyperacidity consume it, they will get worse. Although it is less toxic, it is not suitable for long-term consumption. Please seek medical advice if adverse reactions occur.
