Who knows the scientific name of "broom" in northern Anhui?

Do you mean Schizonepeta tenuifolia? A vegetable, Panicum miliaceum, grows from March to August, and its stem is nearly quadrangular and 30-60 cm long. It likes to pick the core, and it can sprout lateral buds in two or three days after picking the core. According to the shape of its flowers, I think it belongs to Labiatae and may be a variety of Ocimum basilicum. Add a little to the soup to improve the taste. Generally, the soup is cooked before adding it. Don't overcook it, just medium. I have seen it used in western food and hamburgers. I can't confirm whether Schizonepeta tenuifolia is referred to by Chinese herbal medicine, but I have seen practitioners of Chinese herbal medicine go to the countryside to buy its whole grass. I come from Fuyang. Bozhou, the capital of the four major Chinese herbal medicines, was originally a county under Fuyang, and my hometown is 40 kilometers away from there.
