  [Do not touch the flowering three-lobed Pigweed]

  Do not touch the flowering three-lobed Pigweed! It also poses a great threat to agriculture.

  Due to its strong root system and large above-ground nutrition body, Pigweed grows vigorously and competes with crops for water and nutrients. It releases various substances that have obvious inhibitory effects on cultivated crops and wild plants, quickly overpowering local annual plants.

  Pigweed pollen is the main pathogen causing a series of allergic reactions in the human body, known as hay fever.

  The density of Pigweed pollen particles in the air reaches 40-50 particles per cubic meter, which can cause hay fever (autumn pollen allergy) in the population.

  Clinical manifestations of patients include itching of the eyes, ears, and nose, intermittent sneezing, runny nose, headache, and fatigue. Some may experience chest tightness, shortness of breath, coughing, and difficulty breathing.

  If left untreated for a long time, it can also lead to complications such as emphysema and pulmonary heart disease, causing great suffering and even death. Pigweed plants and pollen can also cause some people to develop allergic dermatitis and "wind blisters" all over the body.
