What does a needle look like? I spent 200 yuan on a needle in the street. I wonder if it's really a needle from Yunnan. Can low blood pressure drink a needle soaked in water?

Needle, if right, is also called clock.

Bell, commonly known as red cough flower, is mainly produced in Gongshan and other areas in southwest China. It is a traditional Chinese herbal medicine. It is used as whole grass, but its fruit is often used in clinic. Yunnan and other areas are called endemic medicinal materials, and the fruit ripening mode is like bell, so it is called bell. Also known as: Yunnan Bai Shu Ball, Button VII, Victory Fruit.

This name is not found in general reference books. According to Mr. Xie Zongwan's Dictionary of New Proper Names, the plant corresponding to "one-hole clock" is eucalyptus? Robusta? Smith, eucalyptus grandis of Myrtaceae, whose fruit is used as medicine. Eucalyptus? The fruit of Robusta grandis is called "A Ling", commonly known as "Red Cough Flower", which is mainly produced in Gongshan and other areas in southwest China. It is a traditional folk Chinese herbal medicine in China, and the whole herb is used as medicine, but its fruit is often used in clinic. Yunnan and other places are called "a bell" because of their bell-like fruit ripening mode, and they are also called "Yunnan Ball", "Button Seven" and "Victory Fruit". "One-hole bell" is slightly bitter in taste and flat in nature, and has the effects of invigorating spleen and regulating stomach, lowering blood fat, lowering blood pressure, dredging collaterals and expelling wind, and promoting diuresis. "Sexual Taste" records that its taste is slightly bitter and its nature is flat. There is a kind of "Yikongzhong" drinking crystal (tea), which is made from the fine product of Yikongzhong produced in Yunnan, and has the effects of "invigorating kidney and spleen, reducing blood fat, lowering blood pressure, relaxing muscles and tendons, promoting blood circulation, dredging collaterals and diuresis".

There is also a saying that "A Ling" is a Myrtaceae plant "Eucalyptus globulus" (Eucalyptus? The fruit of the blue fruit tree). Many fruits of Myrtaceae are used as medicine. For example, China's materia medica contains: the fruit of red eucalyptus, the fruit of lemon eucalyptus, the fruit of blue eucalyptus, the fruit of big eucalyptus and the fruit of small eucalyptus, which have different effects. The fruit of eucalyptus globulus has a certain therapeutic effect on cough and stomachache.
